摘要：1275943 Fluid regulation FESTOMASCHINENFABRIK GOTTLIEB STOLL 12 Aug 1969 [13 Aug 1968] 40270/69 Heading G3H An air-pressure impulse generator, comprises an air supply pipe 20, 3, 23, which opens into a passage 10a having therein two nozzles 4 and 5 and an opening 24, the opening leading to an impulse space 1 which is in permanent communication with an output signal passage 25. Nozzle 5 opens into a space 10 which includes an exhaust channel 7 and is engageable by a diaphragm 8 responsive to input signal pulses fed to a space 6. The nozzle 4 and opening 24 are said to constitute a Bordas orifice. In the absence of pressure in chamber 6, air fed to the nozzle 4 flows outwardly through nozzle 5 and in so doing reduces the pressure within impulse space 1 and output signal passage 25. Conversely, when a signal pressure is applied to space 6, diaphragm 8 closes nozzle 5 and so air fed by the air supply pipe is caused to enter the signal passage 25.
