Abstract
A variable capacity wobble plate compressor in which a pressure regulating valve is arranged across a communication passageway communicating between a high pressure chamber and a crankcase, wherein the crankcase pressure is controlled through selective closing and opening of said pressure regulating valve, to thereby vary the capacity of the compressor. An oil guide passage means communicates between a lower portion of the high pressure chamber and an inlet port of the pressure regulating valve. When the pressure regulating valve is open, lubricating oil which has collected in the high pressure chamber is returned to the crankcase through the oil guide passage means, the open pressure regulating valve, and part of the communication passageway.
