Abstract
The profile of the valve stop of a discharge valve is configured such that the portion facing the free length of the valve member has a first fixed radius portion and a second, larger fixed radius portion. The first and second fixed radius portions are tangent at their transition.
Claims6
A discharge valve assembly including a valve stop and a valve member having a tip and a root with a free length therebetween and said valve stop having a profile starting at said root and having a first portion which is of a first fixed radius and which transitions into a second portion which is of a second, larger fixed radius.
A discharge valve assembly including a valve stop having a natural frequency and a valve member movable into engagement with said stop and having a tip and a root with a free length therebetween and said valve stop having a profile starting at said root and having a first portion which is of a first fixed radius and which transitions into a second portion which is of a second, larger fixed radius whereby engagement between said valve member and said stop takes place over essentially an entire opening movement of said valve member thereby maximizing the duration of, and minimizing the amount of, kinetic energy transfer from said valve member to said stop.
