Abstract
The seat of a suction valve of a reciprocating compressor is modified to limit the area in which an annular oil film can be established between the valve and the valve seat. The seat is configured to limit the oil film from 3% to 33% of the total inlet port opening. In a modified embodiment gas at discharge pressure exerts an opening bias to the suction valve at the end of the discharge stroke.
