The piston type compressor includes a cylinder block, a rotary shaft, a plurality of pistons, a rotary valve and radial load transmission means. The radial load transmission means transmits a radial load caused by compression reaction force acting on the piston, which is on its compression stroke of the discharge stroke, to the rotary valve, thereby pressing the rotary valve against an inner peripheral surface of the valve chamber. The radial load transmission means has a direction turning portion for turning the radial load toward the inner peripheral surface of the valve chamber between the suction port communicating with the cylinder bore whose piston has completed the discharge stroke and the suction port communicating with the cylinder bore whose piston is on the compression stroke in a rotation direction of the rotary valve from the suction port communicating with the cylinder bore whose piston has completed the discharge stroke.
