  • Patent number: 8267120
    Abstract: A control valve assembly is provided for a load carrying vehicle that includes a storage space and a dumping mechanism. The control valve assembly includes a housing and a sliding valve positioned within the housing and movable between a first position, and a second position. The sliding valve includes a first piston that defines a first piston first surface and a first piston second surface, and a second piston that defines a second piston first surface and a second piston second surface. The first piston second surface faces the second piston first surface. A pilot system includes a first pilot passage in fluid communication with the first piston second surface to selectively actuate the sliding valve toward the first position, and a second pilot passage in fluid communication with the second piston first surface to selectively actuate the sliding valve toward the second position.

  • Patent number: 7980269
    Abstract: A control valve assembly for a load carrying vehicle that includes a storage space and a dumping mechanism that is movable between an open position that allows access to the storage space and a closed position that inhibits access to the storage space. The control valve assembly includes a housing and a valve that is positioned within the housing and is movable between a first position, wherein the dumping mechanism is moved toward the open position, and a second position, wherein the dumping mechanism is moved toward the closed position. First, second, and third actuation systems are in communication with the valve and are operable to actuate the valve between the first position and the second position.
