Description

200829825 IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to oil feed robbing with a remote feed adapter. [Prior Art] Portable grease guns are commonly used in the industry to supply pressurized grease, to lubricate vehicles and many types of machinery. In the conventional portable hand-held grease, the grease grabs a threaded mount, and the grease "gun" (a tube having a closed end and an open end) containing a certain amount of grease or a sliding box can be connected to The threaded mount is provided to provide a grease slick source. When the slide in the case is exhausted, the cartridge can be removed and a new cartridge inserted, and the cartridge can be reattached to the threaded mount of the grease gun body. This type of grease is limited to being installed on the grease and carried along with the self-carrying grease. This type of grease gun is useful when the user needs to walk around a wide area to lubricate the device nozzle. Other grease guns have connectors that connect to a flexible hose that is connected to a grease supply that can be placed against a surface or other surface without the user having to carry it. This type of grease delivery device is typically a container of large amounts of grease, such as a bucket, bucket or keg. They are equipped with a hand operated or foot operated pump. When the grease is required in the grease gun body, the user extracts a quantity of grease from the grease barrel by operating the hand pump, thereby supplying the grease into the compression chamber of the grease. Existing grease grabs can only be connected to grease hoses. This type of grease gun body is useful when the user can leave grease in a limited area. It is equipped with a grease-carrying grease and a curved bottom for the material to be slipped. 5 200829825 The hand-held portable grease gun with a removable grease barrel is now equipped with an output check valve, which is low in resistance. The pressure in the pressure chamber below about 25 psi is such that grease in the grease cylinder below about 15 psi does not exit through the output nozzle. Resupply of the barrel via the standard resupply port on the grease gun is limited to a low pressure source so that the grease that enters the grease through the supply port is not forced through the output check valve that is coupled to the output nozzle.

There is a need for a versatile grease body that can be supplied by a grease cartridge that is mounted on the body, or by a larger amount of grease contained in a grease bucket, bucket or keg, and It is supplied to the grease by a hose connected to the grease gun body. There is also a need for a versatile grease gun that can be supplied via a standard refill port at pressures in excess of 25 psi, for example via a hose connected to a grease reservoir pressurized with a foot pump. The grease of the present invention solves the above problems. SUMMARY OF THE INVENTION The present invention provides a portable grease gun that can be attached to a hose that accommodates a barrel of grease or that delivers grease from a grease supply container. The grease cartridge includes a threaded fitting that can receive a grease cartridge that can pass through an inlet valve in communication with the interior thereof, or can be replaced by a cartridge in the barrel or by extraction from a bulk container. Refill. When the grease is removed, an adapter can be used instead of a grease cartridge. The adapter includes an accessory that can be fitted with a hose. The adapter includes an external thread similar to the external thread of the grease barrel 6 200829825, the adapter including a soft total, which can be received in a grease cartridge mount.

Figure 1 discloses a grease cartridge 2 according to the present invention which is connected to a grease reservoir 6 by a flexible hose 4. The hose 4 is connected to the grease gun 2 at the adapter 8, which is detachably mounted on the grease gun body 10. In this configuration, by operating the first pump 7, the grease from the storage tank 6 can be forced through the hose 4 and through the adapter 8 into the grease to steal the body 10. This shows that the actuating lever 12 is in the stowed position that is turned away from the handle 14. Referring now to Figure 2, a partial cross-sectional view of the grease cartridge 2 shows that the adapter 8 is preferably mounted to the grease cartridge 10 by the thread 9 at the cartridge mounting seat 16. The grab mount 16 is constructed to receive the end of the grease gun barrel, but when the grease is not installed, the adapter 8 can be screwed into the grab mount 16. The adapter 8 includes a hose connector 18 that receives the male connector and the swivel connection of the hose as shown in Fig. 2. The adapter 8 has a grease chamber 20 in which grease is stored until it is forced through the inlet valve 22 into the pressure chamber 24 of the grease. Since the adapter 8 can be removed from the grease gun body 10, the conventional grease cartridge can be mounted in its position in the barrel mount 16. It should be understood that although the cartridge mount 16 is shown as a threaded mount, other mechanical attachments such as bayonet mounts such as 200829825 may be employed in place of the illustrated threaded mount. The adapter 8 is preferably cylindrical in shape and has an open first end wall 11 which communicates with the cartridge mounting seat 16 and thus with the inlet 15 of the grease gripping body 10. The first end wall 11 includes external threads for mating with the internal threads of the pre-installation mount 16.

The adapter 8 includes a second end wall 17 that houses the hose connector 18. Typically, the second end wall 17 will be smaller than the first end wall 11. The second end wall 17 accommodates the hose connector 18 and is preferably internally threaded 19 to receive a conventional grease hose end connector. The nozzle body 34 of the grease body 10 includes an output check-out spring 3 5, and the output check valve spring 35 is biased to the ball 3 7 so as to be close to the outlet 39. The check valve spring 35 is preferably selected to resist movement of the ball 37 unless the pressure of the grease in the outlet 39 exceeds about 150 psi, however, the check valve spring 35 pressure resistance may also be selected to provide Resistance as low as about 30 psi. When the grease gun body 10 grease is supplied through the hose attached to the adapter 8, the grease which is pumped from the grease tank may easily exceed the conventional grease cartridge shown in Fig. 3 6 In the grease pressure, it is desirable to increase the resistance of the check valve. Figure 3 shows a grease gun 2 having a conventional grease cartridge 26 mounted to the barrel mount 16 of the grease body 10. The grease cartridge 26 can typically hold a 14.5 ounce grease cartridge or it can hold a large amount of grease. As is known in the art, a grease spring biasing follower (not shown) contained in the grease barrel 26 causes the grease in the grease barrel 26 to enter the grease. The grease pressure in conventional grease barrels 26 typically does not exceed 16 psi. When the grease supply in the grease trap 2 6 200829825 is used up, the plunger handle 2 can be pulled from the grease cartridge 26 to compress the coil spring therein, thereby adding the grease to the slip. Inside the grease barrel 26. The grease can then be introduced through a resupply port 30 (also referred to as a replacement fill port) mounted on the grease body 10, which is in communication with the interior of the grease barrel 26. The resupply port 30 is covered when not in use.

Another embodiment of the present invention is disclosed in Figures 4 and 5. The grease gun body 10 is provided with a plug member 40 which can be exclusively received in the cartridge mounting seat 16. The plug member 40 includes a cylindrical side wall 52 and a bottom portion 54 coupled thereto, which together define a hollow portion 50 therein. The hexagonal body 56 is integrally formed with the bottom portion 5 4 and depends from the plug member 40. The hexagonal body 5 6 can be clamped with a wrench to tighten the plug 40 within the cartridge mount 16. The hollow portion 50 is a grease that enters the grease gun body 10 via the resupply port 30, and provides a temporary storage container. Preferably, the cylindrical side wall 52 is provided with an external thread 5 8, which can be received by the internal thread 57 in the cartridge mounting seat 16. Therefore, by removing the grease gun barrel, the grease gun body 10 supplied by the conventional grease cartridge (such as the grease cartridge 26 shown in Fig. 3) can be modified, and the plug can be used. 40 is mounted in the barrel mount 16. The plug 40 completely blocks the grease passage through the barrel mount 16. The resupply port 30 is set in the grease stealing body 10, and when the grease is used conventionally, for example, when the grease is installed in the cartridge mounting seat 16 of the grease grabbing body 1 The refill port 30 is typically covered. When the plug 40 is used in place of the grease cartridge 26, the refill port 30 is uncapped and can then be connected to the distal grease supply. In the embodiment of the present invention 10 200829825 as shown in Figs. 4 and 5, the adapter fitting 4 1 can be exclusively received in the resupply port 30. The grease supply hose 4 can be connected to the resupply port 30 of the grease gun body 10 via a hose connector 43, and the hose connector 43 is coaxially coupled to the adapter connection! 59. The adapter connector 59 is connected in series with the manually operated valve 44. The manually operated valve 44 is in turn connected to the adapter fitting 41. The manually operated valve 44 is inserted between the hose connector 43 and the adapter 41 to prevent the grease from overflowing when the adapter fitting 4 1 is disengaged from the resupply port 30.

The nose 62 of the adapter fitting 4 1 is screwed into a resupply port 30 which is conventionally provided with an internal thread. By the action of the first pump 7, the grease can be forced from the grease reservoir 6 via the hose 4, through the axial passage 60 of the adapter fitting 41, into the resupply port 30. Then, the grease entering the resupply port 30, along the internal passage 61 of the grease gun body 10, enters the hollow portion 50 of the plug 40, from which the grease can be sucked into the grease to steal 1 0 pressure chamber 24. As with the preferred embodiment illustrated in Figures 1 through 3, the check valve spring 35 (see Figure 2) is selected unless the pressure in the outlet 39 substantially exceeds at least 25 psi. The check back spring 3 5 can resist the ball 37 from leaving the seat, so that grease at a pressure far exceeding 16 psi can be introduced through the refill port 30 without passing through the output of the nozzle body 34. Back to the ball 37 leaked out. When the grease is supplied from the distal pump supply unit to the resupply port 30, the reason why the grease cartridge 26 is removed and the barrel mount 16 is removed is that the follower in the grease cartridge 26 cannot be The pressure delivered by the sealed pump 7 is sealed. This can result in leakage around the handle 28 of the grease cartridge 26. The above description of the present invention has been presented for purposes of illustration and description. Various modifications and changes can be made in the above disclosure or in the practice of the invention. The embodiment was chosen to illustrate the principles of the invention and its practical application, so that those skilled in the art can utilize the invention in various embodiments, and various modifications suitable for practical use are contemplated. The scope of the invention is defined by the scope of the appended claims and their equivalents.
