The pressure in chamber 15 and output pipe 53 is proportional to the difference between a variable pressure and a reference pressure applied to , vented chambers 13 and 14 respectively. The chambers are separated by a diaphragm 12 which is connected by links 61, 62 to a member 63 which controls inlet and outlet valves 46, 52 in response to diaphragm movement. Linearly variable resistors 21, 22, 23 are of higher value than vent resistor 41 in chamber 13, and likewise linearly variable resistor 33 is of higher value than vent resistor 42 in chamber 14. A further linearly variable resistor 72 in feedback line 71 constitutes a gain control.</p> |
