Abstract: A variable displacement type swash plate compressor includes a housing having therein a suction chamber, a discharge chamber, a control pressure chamber, a shaft hole, and cylinder bores. The compressor further has a drive shaft, a swash plate, an inclination angle changing mechanism, pistons, introduction passages, and a valve mechanism. The valve mechanism includes a valve element is disposed in a passage connecting the control pressure chamber and the suction chamber. The valve element is integrally rotatable with the drive shaft and axially movable by a pressure difference across the valve element. An opening of the residual gas bypass passage is changed by the axial movement of the valve element. The valve element selectively connects and disconnects the introduction passages with the residual gas bypass passage.
