Abstract

An air shutoff valve includes a passage for supplying air, a swing gate, a shaft attached to a reset handle, and a spring to urge the gate toward its closed position. A trigger assembly secures the shaft and gate in the open position and includes an actuator, a cam, and a rocker arm. A cam surface of the arm has a notch to receive a sear point of the cam. Movement of the handle against the spring causes the cam contact surface of the cam to follow the cam surface to cause the arm to rotate such that the sear point is received in the notch. Actuating the actuator causes the arm to pivot away from the cam such that the sear point is released from the notch, wherein the spring causes the shaft to move the gate to its closed position.
