Combined Check Valve And Fluid Pressure Relief Valve

Filed:

Appl. No.:

Inventors:
Thomas A. Kasper - Agoura Hills CA

Assignee:
Royce Medical Company - Westlake Village CA
International Classification:
F16K 1518, F16K 1520
US Classification:
251 82
Abstract:
A combined check valve and relief valve assembly for permitting the free of a fluid in a first direction and for selectively preventing backflow. Backflow occurs only upon depression of a compression spring-loaded cylindrical valve actuator housed within the valve body. The valve assembly comprises a valve body having an inlet and outlet port which are adjacent to an upper and lower cylindrical bore respectively, thus providing a flow path. A resilient duckbill valve is mounted within the cylindrical bores. A compression spring-loaded valve actuator is also received, lossely, within the valve body and is provided with a stem at the end of the valve actuator, proximate to the opening of the duckbill valve. Fluid passing through the upper cylindrical core around the valve actuator opens the lips of the duckbill valve permitting free passage therethrough. Back pressure seals the lips of the duckbill valve so that the valve becomes a check valve.
