Ventable manifold

摘要

A ventable manifold is disclosed and claimed. Coupling halfs are affixed to coupler ports in the manifold. An actuator having a cam thereon resides in a longitudinal bore in the manifold body and is moveable between first and second positions therein. The manifold includes at least one coupler port and at least one body port for supplying energized fluid to a load. A first passageway is in communication with the coupler port and the body port. A second passageway is in communication with a relief port and the first passageway. A valve is interposed in the second passageway and is in sliding engagement with the cam of the actuator such that when the actuator is in the first position the valve is closed such that when the actuator is in the second position the valve is open. Another embodiment includes a rotatable actuator which can selectively relieve one hydraulic circuit or another.
