摘要： To provide a piston compressor capable of preventing excessive oil from accumulating in a crank chamber in any operation state while securing the supply of oil to a swash plate. In a piston compressor in which an oil separation passage (43) is formed in a shaft (7) and a crank chamber (2) communicates with a suction chamber (31) through the oil separation passage (43), a supply passage (40) opens at a region of a cylinder block (1) opposed to a swash plate (18) to thereby allow a working fluid introduced from a discharge chamber (32) into the crank chamber (2) to be supplied to the swash plate (18) and a bypass passage (50) allowing the crank chamber (2) to constantly communicate with the suction chamber (31) is provided to thereby prevent the accumulation of excessive oil in the crank chamber (2) regardless of the operation condition. The bypass passage (50) communicates with the crank chamber (2) at a region positioned in the outer side of a rotation trajectory of the swash plate (18) in the radial direction.
