GAS-LIQUID SEPARATOR AND AIR COMPRESSOR PROVIDED THEREWITH

摘要

This gas-liquid mixed-type air compressor comprises: a compressed air inflow tube into which compressed air flows that is an air-liquid mixture which, discharged from the compressor main body, precludes a downward velocity component of a swirling airflow in a gas-liquid separator and ensures a sufficient swirl distance; a substantially cylindrical housing main body which is connected to the compressed air inflow tube such that the tangent of the outer circumference of the housing main body and one longitudinal side of the compressed air inflow tube are parallel and in proximity; a compressed air discharge port which is provided in the top wall of the housing main body; a partition tube which encompasses the compressed air discharge port in the radial direction and which extends from the top wall in the direction of the housing main body; and an inflow port which is arranged in a position such that, with respect to the inner radius p of the compressed air inflow tube, the distance q from the topmost end of the inflow port to the inner top wall of the housing main body is q ≧ np (n = natural number excluding 0) and such that the bottom end of the inflow port is higher than the lower end of the partition tube.
