Abstract
An improved valve assembly is disclosed, in which the valve assembly is provided with noise attenuation and is especially well-suited for use in refrigeration compressors. The valve assembly includes a retainer member fixed to a valve plate having a flow opening therethrough with a movable valve member therein between the retainer member and the valve plate. The retainer member edges are spaced relatively close to the valve plate to define a relatively small effective flow area therebetween, with additional effective flow area being provided by one or more openings through the valve plate. This arrangement provides for rapid fluid pressurization in the area between the valve member and the retainer member during valve opening in order to minimize impact forces transmitted from the valve member to the retainer member, thereby reducing noise emanating from the valve assembly.
