ABSTRACT:
A valve assembly has a discharge valve member and a suction valve member. One of these valve members includes a reed valve. The reed valve has a tab which is secured to the valve plate by drive studs prior to assembly of the valve assembly to the compressor. The drive studs include a first set of ridges along the shank of the stud to create an interference with the bore in the valve plate. This eliminates the need to access both sides of the stud to secure the stud. The drive studs included a second set of ridges on the surface of the head which contacts the reed valve. A portion of these ridges extend into the mounting hole in the reed valve and a portion of these ridges are compressed during assembly of the stud. These second set of ridges permit the correct positioning of the reed valve to eliminate build tolerances and the retention of this properly positioned reed valve during assembly of the valve assembly to the compressor.
