Abstract
A unique valve assembly is disclosed which has particular utility in scroll compressors. The valve assembly includes a relatively thin valve plate formed of reed valve steel. The valve plate is less than 0.05 inch, and is elastically deformable upon application of fluid pressure. Thus, the pressure fluid in a chamber formed above the valve plate deforms the valve plate to conform to the valve seat. In embodiments a clip holds the valve plate on the valve seat. The clip provides a stop surface for the valve seat, and is also formed of thin resilient steel. Thus, when the valve plate is driven to its open position, the steel valve plate contacts the steel clip such that there is a spring back effect in response to rapid movement of the valve plate to its open position.
