Title:
LIQUID-SUPPLY-TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/059775
Kind Code:
A1
Abstract:
This liquid-supply-type compressor comprises: a compressor body having a rotor that compresses a gas drawn in together with a liquid supplied to a working chamber, and a casing that houses the rotor; a drive source that supplies driving force to the rotor; and a gas-liquid separator that separates a compressed gas and the liquid from a gas-liquid mixed gas discharged by the compressor body; wherein the gas-liquid separator has a cylinder part inside of which the gas-liquid mixed gas flows through and an opening part into which the mixed gas flows, the vertical positions of the opening part and a discharge port of the compressor body at least partially coincide, and the compressor has a discharge flow channel that guides the mixed gas horizontally to the opening part at an angle of 0 to 90 degrees relative to the direction of discharge from the discharge port. Discharge pressure loss in the liquid-supply-type compressor is thereby reduced.
