A rotatable cylinder block 1 is provided with a plurality of piston chambers 3 that can be expanded and contracted by a plurality of pistons 2 that reciprocate,
A suction port 4 and a discharge port 5 for inhaling and discharging fluid due to expansion and contraction of each chamber 3 are formed in a valve plate 6 that is in sliding contact with the block 1, and between both ports 4 and 5 there is a connection between the ports 4 and 5. In the case where the sections 8 and 9 are formed to close the lower part, openings 10 and 11 are formed in each section 8 and 9 of the valve plate 6 through which the entrance and exit lower part of the chamber 3 faces, and one of the openings is 10 through a check valve 12 that allows fluid to flow from the chamber 3 to the port 5, and the other opening 11 is connected to the suction port 4 to allow fluid to flow from the chamber 3 to the chamber 3. A low-noise pump connected via a check valve 13 that allows fluid flow.
