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 includes a localized through hardened area which provides a wear surface. The remainder to the reed valve has a lower hardness to provide fatigue strength to the reed valve.
