PURPOSE: To surely prevent the clogging of foreign materials in an oil return passage by arranging a valve covering the inlet of the oil return passage, onto the oil storage chamber side of the oil return passage for the communication between an oil storage chamber and the low pressure part in a compressor.
CONSTITUTION: A storage chamber 39 for storing the oil O which is separated and recovered is formed on the projection part 26 of a rear side cylinder block 2, and an expansion chamber 34 and an oil storage chamber 39 communicate through a fine hole 42. An oil returning passage 43 is formed between the bottom part of the oil storage chamber 39 a swash plate chamber 8 as low pressure part, and the oil O in the oil storage chamber 39 is drip-supplied into the swash plate chamber 8, passing through the oil return passage 43. In the oil storage chamber 39, a lead valve 44 is tightening-fixed in the state covering the inlet of the oil return passage 43. The inlet of the oil return passage 43 is always kept in the covered state by the lead valve 44, and the oil O is supplied into the oil return passage 43 in the leak state from the lead valve 44, and the intrusion of foreign materials into the oil return passage 43 is surely suppressed.
