Abstract
1,270,666. Fluid switching circuit. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept. 18, 1969 [Sept. 30, 1968], No.46266/68. Heading F1P. A bi-stable device 10 has an inlet 14 connected to one of the control ports 13, 15, one outlet port 16 vented to atmosphere and the other outlet 17 connected to the control port 19 of a proportional amplifier 11 of which the other control port 20 is vented to atmosphere. The outlet ports 21, 22 of the device 11 are connected to the control ports 24, 25, of a vented proportional amplifier 12 the arrangement being such that when the control pressures at 24 and 25 are equal substantially the whole output of the device 12 is from the vent port 28. The outlet port 16 of the device 10 may also be connected to the port 20 of the device 11 and flow restrictors may be inserted in connections 17 to 19, 16 to 20, 21 to 24 and 22 to 25.
