Abstract
A rapid response valve particularly suited for controlling a jet of fluid of variable duration, the valve having a chamber with a valve seat surrounding a valve orifice, a valve member within the chamber movable toward and away from the valve seat, the chamber having an inlet compartment and an outlet compartment, means being provided to effectively balance the fluid pressure on opposite sides of the valve element when in the closed position so that the valve may be rapidly moved to the open position when actuated, means also being provided to create a venturi effect to assist in rapidly returning the valve to its closed position.
