| Summary: | This invention relates to hydraulic controls for articulating and raising hospital beds and more particularly to a hydraulic control apparatus which uses solenoid valves and an electric pump which can be overridden by manual controls and a manual pump.
A manifold and valve assembly includes a manifold block having an inlet, an outlet, and a conduit in fluid communication with the inlet and with the outlet. The assembly also includes a valve having a portion movable within the conduit between a first position blocking fluid communication between the inlet and the outlet and a second position in which the inlet is in fluid communication with the outlet, a solenoid operable to move the valve from the first position to the second position in response to an electrical input applied to the solenoid, and a lever operable to move the valve from the first position to the second position in response to a manual input applied to the lever. |
