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.
Claims25
A reed valve assembly, comprising:
- an elongated body including
- a 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.
6 more elements
An engine crank case, comprising:
- a crank region;
- a gear region;
- at least two chamfered surfaces for receiving a reed valve assembly, the reed valve assembly controlling gas/fluid communication between the crank region and the gear region;
- and
- a reed valve slot extending from a first chamfered surface to a second chamfered surface, the reed valve slot having a periphery to receive the reed valve assembly,
- wherein the reed valve assembly includes at least one flexible stop adapted and configured to apply a force between the reed valve assembly and a gear cover.
3 more elements
A method of installing a reed valve in a motorcycle engine, comprising:
- providing a crank case including a hole for receiving a gear driven breather valve;
- positioning a pressure actuated reed valve within the hole;
- and
- mounting a cover on the crank case so as to retain the pressure actuated reed valve within the hole.
1 more element
An engine including an engine crank case comprising:
- a crank region;
- a gear region;
- and
- at least two chamfered surfaces for receiving a reed valve assembly, the reed valve assembly controlling gas/fluid communication between the crank region and the gear region,
- wherein the reed valve assembly includes at least one flexible stop adapted and configured to apply a force between the reed valve assembly and a gear cover.
2 more elements
A reed valve assembly, comprising:
- an elongated body including
- a first end including an opening for receiving a spring;
- a second end opposite the first end;
- an internal cavity extending from the second end toward the first end;
- and
- 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
- 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.

A reed valve assembly, comprising:
- an elongated body including
- a first end;
- a second end opposite the first end;
- an internal cavity extending from the second end toward the first end;
- and
- 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,
- wherein an outer surface of the body includes at least one groove formed proximate to the first end of the body;
- 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.
