  • Cam actuated valve assembly with manual and electric activation
    Patent number: 8794266
    Abstract: A valve assembly for selectively enabling discharge of fluid includes a plurality of valves that are selectively moveable between a closed position and an open position and a cam that selectively actuates the valves. The cam is moveable between a first position in which fluid is sealed from discharge by the valves and a second position in which the valves are in the open position. An electrical actuator and a manual actuator are connected to the cam, with both the electrical actuator and the manual actuator being separately operable to move the cam into the second position upon actuation. The valve assembly may further include a housing within which the valves are disposed for movement.
