Reciprocating piston machine with capillary passages on valves for pressure relief
First Claim
1. A reciprocating piston machine (1, 22) comprising a compression chamber with an inlet valve (9) on a suction side and an outlet valve (10) on a delivery side, said valves (9, 10) include a valve body having an elastic valve disc (11, 12) or valve tongue (23, 24), whereby the compression chamber (6) which is sealed off by a reciprocating piston or similar displacer (2) and by the valves (9, 10) has a pressure relief connection between the compression chamber (6) and atmosphere, the valve disc (11, 12) or valve tongue (23, 24) of the valve (9, 10) on at least one of the delivery side and the suction side has at least one capillary passage (18, 19) as the pressure relief connection.

Abstract
A reciprocating piston machine (1) has an inlet valve (9) on the suction side and an outlet valve (10) on the delivery side, which valves exhibit a valve body having a valve disc (11, 12) comprising of an elastomer, whereby the compression chamber (6) sealed off by the reciprocating piston or similar displacer (2) and by the valves (9, 10) has a pressure relief connection between compression chamber and atmosphere. To be able to bring the compression chamber (6) quickly to atmospheric pressure after the reciprocating piston machine (1) has been put out of operation and to be able to bring about the restart of the reciprocating piston machine (1) so as to be load-free in this respect, the valve disc (11,12) of the valve (9, 10) on the delivery side and/or on the suction side has at least one capillary passage (18, 19) as pressure relief connection.
