Abstract

1,255,572. Valves. VALVES & PRODUITS INDUSTRIELS SCHRADER S.A. 12 Feb., 1970 [11 Sept., 1969], No. 6838/70. Heading F2V. [Also in Division G4] A bi-stable fluidic element has a piston 16 slidable to left and right by fluid signals at inlets E2, E3. The piston is'latched in its extreme left or right position by spring-loaded latches 26 or a similar mechanism, Figs. 6-15 (not shown). The piston acts against a valve part 9 connected by rod 12 to valve part 8 and urged rightwards by spring 42. When the piston is in the position shown fluid at inlet E1 cannot pass to outlet S as valve part 8 lies on seat 10. Outlet S is connected to vent P. When the piston is moved to the left by a signal at E3 (which overrides the effect of any signal at E2 because of the different piston diameters) valve part 8 is unseated and valve part 9 lies on seat 11 so that fluid at El passes to outlet S. The piston carries an indicator 17-visible through cover 6. In a second embodiment, Figs. 4, 5 (not shown), the piston has valve parts at both ends, giving complementary fluid outputs S1, S2.
