Abstract

1,242,605. Valves. C. I. WADEFELT. 20 Nov., 1968 [20 Nov., 1967], No. 55067/68. Heading F2V. [Also in Divisions G2-G3] Piston valves 4, 4 controlling the flow to and the exhaust from opposite ends of piston 11 are actuated by a double-acting armature 2 through springs 3 and respond via passages 6, 7 to the pressures on the opposite ends of piston 11.
