Abstract
A compressor discharge valve assembly including a valve seat, a valve cage, and an annular ring-type valve operating therebetween. The valve cage includes a recess into which the valve retracts when in an open position, or in an alternative embodiment, the valve cage includes a lip portion for shielding the valve. In either embodiment, a reduction in valve flutter and the noise, known as chatter, which results from valve flutter is realized. The valve in alternative embodiments also includes an annular dished portion oriented toward the valve seat for directing the flow of discharge gas smoothly from the compressor and thereby further reducing valve chatter.
