[Problem] To provide a piston compressor capable of ensuring the supply of oil to a swash plate while preventing, in any operational state, excess oil from accumulating in the crank chamber. [Solution] A piston compressor in which an oil separation passage (43) is formed in a shaft (7), and in which a crank chamber (2) is connected to a suction chamber (31) via the oil separation passage (43); wherein an air supply passage (40) opens at a position in a cylinder block (1) so as to face a swash plate (18), thereby enabling a working fluid, which is introduced to the crank chamber (2) from a discharge chamber (32), to be supplied to the swash plate (18); and a bypass passage (50), which always connects the crank chamber (2) and the suction chamber (31), is provided, thereby preventing the accumulation of excess oil in the crank chamber (2), regardless of the operational state. The bypass passage (50) and the crank chamber (2) are connected at a position located radially beyond the rotational trajectory of the swash plate (18). |
