Claim 10:
11. A pressure relief valve assembly comprising:
a body with at least one flow passage in the body providing at least part of an opening to the exterior of the body;
a normally closed check valve in the at least one flow passage in the body which when closed prevents the flow of compressed gas through the at least one passage and to the exterior of the body and when opened permits flow of gas through the at least one passage and to the exterior of the body;
an actuator pin slidably carried by the body and movable relative to the body to an advanced position opening the normally closed check valve and to a retracted position permitting the check valve to close; and
a knob connected to the actuator pin and having threads engaged with complementary threads carried by the body and rotatable in one of a clockwise or counterclockwise direction to advance the actuator pin relative to the body to open the check valve and rotatable in the other of the clockwise or counterclockwise direction to retract the actuator pin relative to the body to permit the check valve to close,
wherein the actuator pin has a stop portion engageable with the body to limit the extent to which the actuator pin can be advanced relative to the check valve by rotation of the knob.
