Abstract
A double-headed piston type swash plate compressor includes a swash plate, a double-headed piston, a control pressure chamber, a discharge pressure region, a suction pressure region, a supplying passage, which extends from the discharge pressure region to the control pressure chamber, a narrowing portion, which narrows an opening degree of the supplying passage, and a displacement control valve. The displacement control valve controls a pressure in the control pressure chamber. The displacement control valve includes a driving force transmission rod, a valve chamber, a guide wall, and a back pressure chamber. The back pressure chamber is in communication with the valve chamber through a clearance between the guide wall and the driving force transmission rod. The narrowing portion has a passage cross-sectional area that is larger than a passage cross-sectional area of the clearance.
