Description

Basically auth. St. No. 86805 describes a device for pre-lubrication of an internal combustion engine using an oil accumulator, made in the form of a cylinder with a spring-mounted piston.

In order to move the piston, the cylinder of the battery is connected to the air balloon by means of a luianaHOB controlled from the driver’s cabin.

The automatic start of the electric starter after pre-lubrication of the engine is carried out by closing the contacts with a rod connected on the side of the piston.

In order to reduce the discharge of oil into the cylinder of the battery, in the initial period of engine operation, there is a calibrated bore between the oil supply line and the cylinder of the battery.

The disadvantages of such a device include the need to install an additional cylinder of compressed air, as well as the control of air taps, which complicates both the device itself and its operation.

In the device described, these disadvantages are eliminated by bleeding air from the braking system of the motor vehicle to move the piston of the oil accumulator and by installing a ball check valve between the oil supply line and the cylinder of the oil accumulator.

The drawing shows a device for pre-lubrication of an internal combustion engine.

According to this scheme, from the crankcase 1 of the engine, the pump 2 delivers oil through the coarse filter 3 and the ball check valve 4 to the lubrication line 5 of the engine.

There are also openings for oil drainage to the compressor b and to the sensor 7 of the oil pressure gauge 8. One of the holes plugged by the plugs can be used to connect the tube 9 to the cylinder 10 another oil accumulator.

When the engine is operating, the specified cylinder 10 is filled with oil, and the piston 11 will be moved to the right-most extreme position. The piston 11 has a seal that prevents its oil from penetrating into the right side of the cylinder 10. When the engine is stopped, cylinder 10 will be no, that is 1; filled with oil.

When starting the engine, the driver must depress the air brake pedal 12 before pressing the starter button. At the same time, the compressed air present in the air collector 13 of the compressor 6 rushes through the brake control valve 14 to the front 15 and rear 16 brakes of the machine and at the same time through the tee 17 through the tube 18 to the right side of the cylinder 10 of the oil accumulator and squeezes out mpg-east el 5 engine. In this case, a ball sample:} LI valve 4 is used will allow the oil to go back to the coarse filter 3 and through the pump 2 to the crankcase 1.

If the piston seal 11 misses the oil in the right side of the cylinder 10, then this oil can be blown out of air m through the hole 19, which has a plug in the thread.

In order to prevent oil seeping into the air line, a needle valve 20 of a carburetor-type type 20 can be installed in the tube 18 in the cylinder 10.

The valve freely admits and exhausts air into and out of the cylinder, but when the engine is running, when the piston 11, having moved to the right, rests against the end of the needle of valve 20 and presses it to the seat, the leaked oil will not be able to penetrate the tube 18.

Subject invention

1. The form of execution of the device for preliminary lubrication of the internal combustion engine according to the ed. St. No. 86805, characterized in that, in order to increase the oil supply from the oil accumulator, a ball check valve is used, installed in parallel with the calibrated orifice between the oil supply line and the cylinder of the accumulator.

2. Method of operation of the device for pre-lubrication of the internal combustion engine according to ed. St. N ° 86805, distinguished by the fact that, in order to use the air braking system of a motor vehicle, compressed air is discharged through a tube from the braking system and fed through a needle valve to the oil accumulator cylinder.
