ABSTRACT:
A swash plate compressor is disclosed which is provided with a compression capacity control apparatus capable of returning an output pressure of a high pressure chamber of one cover to a low pressure chamber of the same cover. The control apparatus comprises a delivery chamber which is communicated with a high pressure chamber of the other cover, isolated from the high pressure chamber of said one cover and connected to a delivery conduit. The control apparatus also comprises a compression capacity control passageway providing communication between the delivery chamber and the low pressure and high pressure chambers of said one cover. A valve member is disposed in the control passageway to interrupt the communication between the delivery chamber and the high pressure chamber of said one cover while establishing communication between the low pressure and high pressure chambers of said one cover.
