ABSTRACT:
A compressor valve with annular valve members or rings instead of the usual spring-urged engagement of the rings with the valve seat, the rings are drawn into engagement with the seat by air or other gas passing through the valve in a direction reverse to that opening the valve. Thus, on reversal of the flow, the rings are virtually instantly brought into engagement with the seat without the need for springs bringing the valve rings into closed state. Both faces of the valve rings are identical. When one face is worn, the rings can be turned over to utilize the second valve face. The advance is in simplified structure, increased reliability and in longer operation life of the valve rings.
