SU25413A1 - A device for refueling tractor oil - Google Patents

Description

The invention relates to devices for dispensing liquid materials, which is a vessel, equipped with a graduated scale and two valves, one air and another drainage, connected to each other by means of a rigid rod and closed by spring pressure, acting on this rod. In the proposed device, the graduated vessel fills with a bottle when it is pushed into it through the throat equipped with a gland packing, and in order to dilute the oil during the cold season, the walls of the can are double, forming a jacket through which exhaust gases are passed as needed In order to communicate the inside of the can with the outside air, the can is fitted with a non-return air valve that opens automatically when the vessel is filled with oil.

The schematic drawing shows a vertical section of the tool.

The device consists of a tank 4 for refilling tractors with oil and from a can 1 for filling the tank itself. The tank 4, nd | is strictly cylindrical, provided with a fitting 3 and two valves 7 and 8, which are closed under the action of a spring on a rigid rod connecting them. The ring 8 is fixed on the valve 8, and the bracket 5 is on the tank lid, with the tank equipped with a graduated scale.

The double walls of the can 1 form a jacket 2 through which, in order to liquefy the oil, exhaust gases are passed into the cold season. The upper walls of the can are fitted with a non-return air valve 14 and a throat 13 through which the tank 4, in order to fill it with oil, is pushed inside the can. For tight coverage of the tank 4, the throat is equipped with a gland seal.

When the tank 4 is lowered into the can, the valve 14 is adjacent to its seat, and the oil, lift the valve 7. and 8, enters through the fitting 3 into the tank, and the air from the tank goes through the valve 8. When the tank is lowered, valves 7 and 8 under the action of the spring is once again sad ts on its saddles. When the tank 4 filled with oil is removed from the can, the valve 14 is automatically lowered and communicates the inside of the can with the outside air.

When filling the tractor, the tank 4, supported by the bracket 5, is inserted into the opening of the crankcase with its fitting 3, after which the valve 8 is raised with the help of ring B, and together with it the valve 7, and releasing the required amount of oil, on the scale, the valve 8 is again released, which causes the valve 7 to re-seat and stop the flow of oil from the tank.

To prevent dust from entering the can when the canister is removed from it, the neck 13 is closed with a lid.

The subject matter of the invention.

A device for refueling tractors with oil using a known type of tank for bottling, characterized by

The fact that the can 1 for feeding the tank 4 for the purpose of heating and diluting the oil during the cold season has double walls for the passage of engine exhaust gases between them, and for the purpose of hermetically closing the opening through which the tank for its filling moves into the can the latter is provided with a throat 13 with a gland seal, whereby for access of air into the can 1 when the 4-bottle filled with oil is withdrawn from it, the 4-can is equipped with a non-return air valve.
