<p>An intake or exhaust valve of a compressor comprises a seating plate (10) and a guard plate (12). The seating plate (10) has a plurality of clusters (66, 68) of holes (16) extending through the seating plate (10), the holes (16) of each cluster (66, 68) being arranged along a respective circular locus and communicating with respective seating surfaces (72, 74) opening through an inner surface (70) of the seating plate (10). The guard plate (12) defines a respective stop surface (89) spaced from the seating surfaces (72, 74). A respective annular seal ring (20) reciprocates between each stop surface (89) and the respective opposed seating surfaces (72, 74). A plurality of springs (22) each engage a respective one of the seal rings (20) to bias the seal ring (20) toward its seating surfaces (72, 74).</p> |
