ABSTRACT:
A device for controlling fluid flow wherein a movable ball at a central location on a concave surface of a support prevents upward movement of an actuating element, such as a valve stem to prevent a specific function, such as the closure of a valve, until the ball moves laterally along the concave surface. A spring biases the element upwardly but the weight of the ball is greater than the bias force of the spring. When the ball moves laterally, the element moves upwardly through the concave surface and projects above it to prevent return of the ball to the central position on the concave surface until the stem is again forced downwardly, such as by a pivotal lever engaging a projection on the element to shift the latter. Means is provided in the device for adjusting the bias force of the spring.
