Abstract

1322402 Valves UNIVERSITY OF ILLINOIS FOUNDATION 18 Aug 1970 [18 Aug 1969] 22820/72 Divided out of 1322401 Heading F2V Operation of solenoid 103 acts to close one of the pilot valves 100, 102 and open the other. Pressure in one outlet passage 94, 114 and one chamber 92, 106 rises while the pressure in the other passage and chamber falls so that a diaphragm 104 is flexed to close the inlet passage 108, 86 entering the chamber at the lower pressure. Pressure inlet 84 is thus connectable to opposite sides of a piston 120. The valve is used to position a playback head, as described in Specification 1,322,401 (Division G4-G6).
