摘要：
The seat of a suction valve of a reciprocating compressor is modified to limit the radial extent and thereby the area in which an annular oil film can be established between the valve and the valve seat. The preferred radial extent of the seating surface is 0.014 to 0.018 inches and the preferred ratio of the area of the suction valve seat to the passage therethrough is in the range of 13% to 25%.
