Abstract

FIELD: engines and pumps.

SUBSTANCE: invention can be used in servicing internal combustion engines (ICE). Crankcase pan plug comprises external thread, gate, spring, hose nozzle and hose section. In the upper part of the plug there is a hole with a shutter, from below there is a hole for a hose nozzle. Spring is made with possibility of pressing the shutter to the sealing gasket. On the upper part of the plug there is a stop for the spring. Hose nozzle is designed so that to enable interaction with the gate, and a section of hose is put on the hose nozzle. Hole for the shutter is made conical with a shelf. Shutter is round and flat. Gasket is made of oil and petrol resistant rubber. Spring support is cross-shaped. There is a magnet on the flap on top. Lower hole for hose nozzle is made with internal thread. Hose nozzle is made in the form of a union with an external thread, in the threaded end of which there are cuts (9). When screwed, the union is made with possibility of extension of the shutter into the wider part of the conical hole of the plug. Said shutter can form circular clearance with plug inner walls. Cuts (9) in the threaded end of the union are made with the possibility of passing the drained oil into the hose.

EFFECT: higher safety of ICE servicing and environmental protection.

Description

The invention relates to vehicles, namely to servicing internal combustion engines (ICE).

To maintain the operability of the internal combustion engine, it is necessary to change the engine oil at regular intervals. However, this maintenance work is associated with some inconveniences. To reduce the viscosity and increase the fluidity of the oil, especially in winter conditions, it is recommended to drain it on an engine warmed up to operating temperature, while the oil temperature is comparable to the temperature of the coolant - about 100 ° C. A tray or trough is used to collect the used oil. When unscrewing the sump plug by hand, you can burn yourself with the leaking oil, but if you do this with an open-end wrench, the plug will fall into the tray with hot oil. In addition, the hot stream of used oil flowing out of the sump hits the bottom of the tray and splashes in all directions, so you need to protect your eyes, face and hands from scalding drops. The splashed oil penetrates the soil, negatively affecting the environment.

The aim of the claimed invention is to develop a device that allows one to get rid of the above-mentioned disadvantages.

The solution to the technical problem is provided by the proposed design of a drain plug that is interchangeable with the standard oil pan plug, but it does not need to be unscrewed to change the oil.

The essence of the claimed technical solution is explained by the description of an example of its preferred implementation in combination with the attached drawings. The same position numbers are used throughout the description and on all drawings to designate the same components and parts. The numbering is done in the order of the mention in the description. The device in the drawings is oriented as it is located on the oil pan.

Fig. 1 shows the proposed plug, which has a conical opening 1 with a shelf 2 in the upper part, and a hole 3 with a thread at the bottom. A round flat flap 4 is placed in the conical opening 1 of the plug. In the operating mode, the spring 5 presses the flap 4 to the shelf 2 through the sealing gasket 6, made of oil-resistant rubber. A cross-shaped stop 7 for the spring 5 is fixed on the upper part of the plug. A magnet 8 for catching metal wear products is located on top of the flap 4.

The specified plug is equipped with a hose fitting with an external thread (Fig. 2), in the threaded end of which notches 9 are made, and a section of hose is put on the hose nozzle.

To drain the used oil, it is not necessary to unscrew the plug described from the pan. First, the free end of the hose section of the nipple must be lowered into a container with a narrow neck, convenient for subsequent transportation of the used oil to the disposal site, for example, into a bottle or canister from under the oil. Then the nipple is screwed into the threaded hole 3 of the plug and rests from below against the shutter 4. With further screwing, the nipple, overcoming the resistance of the spring 5, lifts the shutter 4 and moves it into the wider part of the conical hole 1 of the plug, as a result of which a circular gap is formed between the edge of the shutter 4 and the walls of the plug. Through this gap and cuts 9 in the threaded end of the nipple, the drained oil flows out through the hose section into the prepared container, without penetrating outside. After all the used oil has drained from the pan, unscrew the nipple from the plug, holding it from unscrewing with an open-end wrench. Spring 5 will return valve 4 to its place and press it, securely closing hole 3.

Using this device, unlike the existing oil change procedure, will allow you to leave after such work with clean hands and unstained clothes and shoes.

The essence of the claimed invention is that a design of a drain plug is proposed that is interchangeable with the standard oil pan plug, but it does not need to be unscrewed to drain the oil.

The technical result of the claimed invention is to increase the safety of internal combustion engine maintenance work and protect the environment.

The specified technical result is achieved due to the proposed design of a drain plug that is interchangeable with the standard oil pan plug, which prevents the oil from splashing when draining.

A safety feature is to use a drain plug on the oil pan to prevent the drained used oil from splashing out.

The new essential features of the claimed invention are:

- a design of a drain plug has been proposed that is interchangeable with the standard oil pan plug, which prevents oil from splashing when draining;

- improving the safety of internal combustion engine maintenance work;

- reducing the negative impact on the environment when changing oil;

- such a plug can be used in the gearbox, transfer case, reducers, and also in the radiator to drain the coolant.

This description and drawings do not limit the scope of the invention, and are intended for sufficient disclosure of information, are an example of the invention, and although a preferred embodiment thereof has been presented above, it should be understood that the present invention is not limited to the variants and modifications presented here, the present description is illustrative rather than restrictive.
