System for supplying oil to a rotary piston compressor cooled by oil injection

摘要

The invention relates to a system for supplying oil to a rotary piston compressor driven by an internal combustion engine and cooled by oil injection, having a coarse oil separator and a fine oil separator and having a conduit connecting the suction connection of the rotary piston compressor to the intake system of the internal combustion engine. In order to produce compressed air for the pneumatic auxiliary drives in vehicles with internal combustion engines in a simple, space-saving and economical manner, the invention proposes that the injection conduit (4) for the cooling and lubricating oil opening into the working space of the rotary piston compressor (1) and the conduit (15) carrying away the oil separated out in the coarse separator (12) be connected to the lubricating oil circuit of the internal combustion engine. <IMAGE>
