Abstract

1,271,228. Fluidswitching circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept. 12, 1969 [Sept. 30, 1968], No.46265/68. Heading F1P. A fluid switching circuit comprises a bi-stable device 10 having a pair of control ports 14, 15, one outlet port 13 connected directly to one control port 22 of a proportional amplifier device 17 and the other outlet 12 connected to the control port 28 of a monostable device 24, having its outlet port 29 connected to the control port 23 of the device 17. The device 17 has an inlet 18 connected to a pressure source P whilst the inlets to devices 10 and 24 are fed through restrictors. The device 24 may be replaced by a bi-stable device biased to provide an output only when an output appears at the device 10 from the port 12.
