SU20416A1 - Modification of automatic steam oilcan with spring differential piston, characterized in US Pat. No. 5920 - Google Patents

Description

Patent No. 5920 describes an automatic steam engine lubricator with horizontal positioning of a spring differential piston, equipped with a reservoir containing lubricant, and a suction valve with a special tide, allowing the lubricant to be selected when the level drops below the intake valve.

In the proposed modified automatic lubricator, the dfferential piston is located vertically, while the suction valve, equipped with a grid, is located at the bottom of the reservoir enclosing the lubricant to supply the last gravity flow to the piston of small diameter, due to which there is no need for a special tide.

In the drawing of FIG. 1 depicts a longitudinal section of the proposed oiler; FIG. 2 is a view of the lubricator on the side of the discharge valve; FIG. 3 shows a half of an oil can at the bottom and FIG. 4 is a view of the top part of the oil can.

The oil can consists of a reservoir 1, molded together with two cylindrical chambers — on the top of the larger one and on the bottom of the smaller diameter. In these chambers, the differential piston 5 can be moved up and down, pressed upwards by the spring 4. At the bottom of the tank 1 there is a special tide in which the valves are placed: suction 6 and pressure 7. The oiler can be driven in motion by nar or air, the supply and removal of which is carried out through nozzles 9, 9. Two grids 11 and 15 are used to clean the oil from mechanical impurities, of which the latter is located above valve 6. In order to ensure constant atmospheric pressure inside tank 1, and also for Suggested Measures overflow reservoir and ejection smazkoZ g latter at its boiling or foaming of the oil can, provided the discharge tube 14, open at the top and bottom and inbound -Custom upper end in noj 11 mesh smallness.

The lubricator is connected through the top / fitting 9 using a tube from one of the cavities of the steam or air / lindra machine lubricated. When / lpndre steam inlet i occurs

The cavity, which is connected to the hell space by the piston 5, the last vapor pressure is driven downwards. When the pressure drops from the cylinder to about atmospheric, the spring opens, pushes the piston up. When the lubricator is working with air, the piston 5 goes down, when the air is compressed in the cylinder and up when the suction goes there, and in both cases (when operating with steam and air) the double displacement piston of the lubricator corresponds to the double stroke of the working machine. When moving upward, the small piston relieves more or less, depending on the stroke regulated by the set screw 8, a volume that is quickly filled with lubricant flowing through the valve 6. Since the liquid level in the tank 1 is always above the space T1OD, the small piston then the most insignificant dilution under it is sufficient for the lubricator to properly supply lubricant.

The subject of the patent.

Modification of an automatic steam oilcan with a spring differential piston, described in patent No. 5920, characterized by: 1) horizontal - vertical arrangement of differential piston 5, 2) location of suction,. equipped with a mesh valve 6 at the bottom of the tank 1 for the purpose of supplying lubrication by gravity to a small diameter piston and eliminating a special tide at the indicated valve, 3) using a drain pipe 14, open at the top and bottom, not reaching the top end of the tank 1 and intended for elimination of overflow of the tank 1 with grease and ejection of the last of the oiler when it boils or foaming, and 4) the possibility of using for the operation of the oiler in addition to a pair of compressed air.
