ABSTRACT:
An automatic valve for a pressure suit. The valve has a valve body with an inlet port therein having an actuable valve member to admit pressurized gas in a valve chamber in communication with a suit to which the valve is secured. An adjustable cover member is displaceably secured to the body and has at least one exhaust orifice. An outlet port is provided in the body and communicates with the valve chamber and has an automatic pressure regulating valve mechanism therein. The valve mechanism is adjustable by a pressure biasing member controlled by a first displacement of the adjustable cover member to control the pressure of the gas in the suit by automatically exhausting some of the gas through the outlet port when the internal pressure exceeds a preset pressure of the mechanism. A displaceable valve member is associated with the valve mechanism and displaceable by a second displacement of the cover member to exhaust gas from the valve chamber and the inside of the suit through the outlet port.
