ABSTRACT:
A valve for controlling release of a pressurized fluid comprising a housing having a fluid chamber with an inlet and an outlet port. A piston within the housing is slidably movable between a sealed closed position and an open position. A collapsed support structure, when in a rigid condition retains the piston in the closed position. When the support means is in a collapsed condition, fluid pressure will cause the piston to slide to the open position of the valve. This support structure includes a pair of elongated supports oriented in one of a dead-center locked condition when the piston is sealed, and in an off-center collapsed condition allowing the piston to move to its open position.
