1. A reed valve assembly, comprising:
- an elongated body includinga first end;
a second end opposite the first end;
an internal cavity extending from the second end toward the first end;
at least one opening between the first end and the second end, the at least one opening extending from an outer surface of the body to the internal cavity; and
a metered oil flow region extending from the second end toward the first end; and
at least one flexible member having a periphery so as to substantially cover the at least one opening when positioned adjacent to the body, the at least one flexible member being pressure wave actuated from a closed position to an open position.

Abstract
A reed valve assembly is provided with a body, at least one flexible member, and at least one rigid member. Preferably, the at least one flexible member has a periphery so as to substantially cover opening(s) in the body when positioned adjacent to the body, and the at least one rigid member has a periphery so as to limit deformation of the at least one flexible member.
