ABSTRACT:
A valve seat and valve guard are coupled together, and form a chamber therebetween within which a valving plate moves. A stud secures the seat and guard together, and has a bore formed therewithin for receiving a headed piston. The piston has a projecting rod which engages the valving plate, and a pilot hole formed in the stud addresses a pressured fluid thereinto for moving the piston, causing the rod to move the plate laterally in the chamber. Apertures in the seat, guard and plate align, when pressured fluid enters the seat apertures, as the plate rises from the seat, and combines with the lateral movement to displace the plate diagonally in the chamber.
