ABSTRACT:
An improved valve plate assembly is disclosed herein which is particularly well suited for use in compressors and particularly refrigeration compressors employing pressure responsive reed type valving. The present invention provides several arrangements whereby the velocity of valve member may be reduced as it moves into a closed position so as to substantially reduce the resulting noise generated therefrom.
