Abstract
A release valve for connection to an inflatable cushion comprising an air conduit, a fitting at a first end of the air conduit for insertion into an air tube in fluid communication with the interior of the cushion, and an air inlet port at the opposite end of the air conduit and a filter assembly at the air inlet port. There is first, vertically orientated, spring biased ball valve centrally positioned in the air conduit including at least one air egress vent and being operatively associated with a spring biased actuator in the ball valve housing for opening the first ball valve. The button and first ball valve define a gap to minimize accidental air release. A second longitudinally orientated, spring biased ball valve is positioned in the air conduit adjacent the air inlet port.
