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.

Abstract translation: 空气截止阀包括用于供应空气的通道，摆动门，附接到复位手柄的轴和用于将门推向其关闭位置的弹簧。 触发器组件将轴和门固定在打开位置，并且包括致动器，凸轮和摇臂。 臂的凸轮表面具有凹口以接收凸轮的冲击点。 手柄相对于弹簧的移动导致凸轮的凸轮接触表面跟随凸轮表面以使臂旋转，使得冲击点被容纳在凹口中。 致动致动器使得臂离开凸轮枢转，使得冲击点从凹口释放，其中弹簧使轴将门移动到其关闭位置。
