Abstract

ESSAY

Pneumatic Pneumatic Compressor Lubrication System

The utility model relates to transport engineering, namely to the lubrication system of a pneumatic compressor located on an internal combustion engine.

The technical result - the ability to optimally position the compressor on the engine and the evacuation of oil from the compressor forcibly without the use of additional devices.

This is achieved by the fact that the compressor is mounted on the engine with an excess of oil level in the crankcase relative to the oil level in the compressor crankcase, and the outlet of the oil drain pipe from the compressor is brought out above the oil level in the compressor crankcase.

Pneumatic compressor lubrication system.

The utility model relates to transnational engineering, namely to the lubrication system of a non-pneumatic compressor located on an internal combustion engine.

P1 known is a non-pneumatic compressor lubrication system containing an internal combustion engine, a single-cylinder pneumatic compressor mounted on an engine, a pressurized oil supply pipe from the engine lubrication system to the compressor, a seal, a crankshaft with oil channels, a compressor oil drain pipe, fixed to the receiving part at the bottom parts of the compressor crankcase and the output part to the engine crankcase above the oil level in the engine crankcase, and the oil is drained from the compressor to the engine n by gravity for which the compressor is mounted on the engine above the oil level in the crankcase, and the receiving part of the oil drain pipe is located above its output part. 1.

Such a technical solution in some cases may be unacceptable from the condition of the optimal location of the compressor under the hood of the car, since if the oil level in the engine is higher than the oil level in the compressor, it is necessary to ensure the forced evacuation of oil from the compressor.

The technical result achieved by the claimed solution allows you to optimally position the compressor on the engine and the EVMTZh F 04 at 39/02 t force oil from the compressor forcibly without the use of additional devices. This result is achieved by the fact that the compressor is installed on the engine with an excess of oil level in the crankcase relative to the oil level in the compressor crankcase, and the outlet of the oil drain pipe from the compressor is brought out above the oil level in the compressor crankcase. The claimed technical solution is illustrated by the drawing. The lubrication system of a pneumatic compressor comprises an internal combustion engine 1, a pneumatic compressor 2 fixed to the engine, to which oil is supplied under pressure from the engine lubrication system through a pipe 3, a seal 4, a crankshaft with oil channels 5, an oil discharge pipe from the compressor 6, the outlet which is derived above the oil level in -g; compressor crankcase .; t,; The lubrication system works as follows: Oil is supplied under pressure from the engine lubrication system through the oil supply pipe 3, then through the seal 4 into the oil channel of the crankshaft 5, and passing through the clearances in the connecting rod bearing, it accumulates in the lower part of the compressor housing. There is a vacuum in the engine crankcase above the oil level, and when the compressor piston moves downward due to a decrease in the volume of air under the piston, increased pressure is created. Due to the pressure difference in the crankcase and the compressor housing below the piston, oil accumulated in the compressor housing through the drain pipe 6

ejected from the compressor into the crankcase, while ensuring the circulation of oil in the compressor lubrication system.
