ABSTRACT:
A dump valve apparatus is configured to inflate and deflate an air cushion on a bed having an articulating deck movable from a first generally horizontal position to a second angled position. The dump valve apparatus is coupled to the deck and includes an elongated housing having an interior region. The housing has first and second open ends and a central opening located between the first and second open ends. The central opening is coupled to the air cushion. The first end of the housing is coupled to an air supply. A piston is slidable within the interior region of the housing of the housing as the deck moves to its angled position to permit air to pass from the air bladder, through the central opening, and through the open second end of the housing to deflate the air bladder.
