<p>PURPOSE: To avoid delay of valve closing movement and deterioration of discharge properties of a compressor by arranging a plurality of protrusions distributed throughout the area of a valve plate and passage-shaped recesses between the protrusions. CONSTITUTION: A compressor valve comprises a valve seat 1 that has a plurality of flow channels 2, and a catcher 3 spaced apart from the valve seat 1. A valve plate 8 moves reciprocally between the valve seat 1 and the catcher 3. A plurality of protrusions 12 distributed throughout the area of a valve plate 8 are arranged. Passage-shaped recesses 19 are arranged between these protrusions 12. Thus it is possible to avoid delay of valve closing movement and deterioration of discharge properties of the compressor.</p> |
