FIELD: pumping equipment.
SUBSTANCE: invention relates to the device of a compressor or a vacuum pump with a liquid return system containing a main body with multiple inlets and outlets, while one of the inlets is in a fluid connection with a gearbox. A device of a compressor or vacuum pump with liquid injection with an element (2) of a compressor or vacuum pump with liquid injection, which contains a liquid return system (7), an engine (4) for actuating an element (2) of a compressor or vacuum pump, a gearbox (3) provided between the engine (4) and the element (2) a compressor or vacuum pump with liquid injection, and a reservoir (5) of a liquid separator in a fluid connection with the outlet (6) of an element (2) of a compressor or vacuum pump with liquid injection. The liquid return system (7) comprises a main body (8) with a chamber in which the first stream (11) of compressed gas from the reservoir (5) of the liquid separator and the second stream (15) of fluid from the gearbox (3) are mixed together to form a third stream (20) of fluid. The third fluid stream (20) leaves the chamber through the outlet (16) and is directed to the compressor or vacuum pump element (2) with liquid injection through the injection point (17).
EFFECT: ensuring the return of liquid that has leaked into the gearbox due to a seal malfunction to the compressor or vacuum pump element in order to perform its function of lubrication, cooling, sealing and/or corrosion protection of moving parts of the compressor or vacuum pump element there again.
