ABSTRACT:
A swash-plate type compressor is provided with an oil pumping chamber which communicates with a fluid pumping chamber within which fluid is compressed by a piston, and also provided with a secondary oil reservoir chamber which communicates with an oil feeding bore formed in the drive shaft of the compressor. The oil pumping chamber communicates with a primary oil reservoir chamber through a first oil feeding passageway, and with the secondary oil reservoir chamber through a second oil feeding passageway, respectively. First and second valves are arranged to open and close the first and second oil feeding passageways, respectively, in response to changes in the pressure within the oil pumping chamber.
