Abstract
A piston compressor contains at least one cylinder (2), inside of which a reciprocating piston (4) forms two working chambers (10, 12) disposed on opposing sides of the piston, which each have at least one inlet and one outlet opening, in which a respective inlet valve (20, 22) or an outlet valve (24, 26) operates. A housing (32) surrounds the cylinder, and has a suction port (34) and an exhaust port (36). A space between the cylinder and the housing is divided by a separating wall (28, 30) in such a way as to connect the suction port with the inlet openings and the exhaust port with the outlet openings. A driving arrangement (42, 44) reciprocally moves the piston. The inlet valve of one working chamber opens and the inlet valve of the other working chamber closes for each stroke of the piston, and the outlet valve of the one working chamber closes, while the outlet valve of the other working chamber opens.
