Abstract
1393080 Valves HYDROMATIK GmbH 18 March 1974 [19 March 1973] 11896/74 Heading F2V [Also in Division G3] In a pressure relief valve, a loose ball closure member 1, lightly loaded by a spring 9, is held on its seating 3 by fluid pressure in the controlled space fed by a restricted passage 7 to a pilot chamber 8 on the far side of the ball. The ball is a sliding fit in an elastically deformable sleeve 8 having an exhaust outlet 10. As the area of the ball exposed to the pressure in the pilot chamber is greater than that exposed at the opening in the seating 3 the ball is held on its seating until a pressure is reached at which the sleeve expands to allow pressure in the pilot chamber to fall thus allowing inlet pressure to lift the ball off its seat.
