Abstract

1404740 Servosystem HOERBIGER VENTILWERKE AG 5 April 1974 [13 April 1973] 15139/74 Heading G3P A system for controlling the delivery of a compressor 1 adapted to be driven at varying rotational speeds by a prime mover 2, comprises a pneumatic servo-mechanism 9, controlled by a proportional regulator 12, which varies the speed of prime mover 2, the compressor being adapted to be switched to an idling condition when a lower control limit is reached, a switch 16 being adapted to be actuated by mechanism 9 both for stopping and restarting the compressor delivery. Switch 16 comprises a valve 20 connected to the compressor suction valve 3 and to the pressure vessel 7, and actuated by a cam 21 carried with lost motion by an adjustable rod 17 actuated by servo 9. In operation, compressor 1 is driven by an internal combustion engine 2 at full speed until a predetermined delivery pressure is reached, whereupon regulator 12 actuates servo 9 which displaces an injection pump 11 to thus reduce the engine, and therefore the compressor, speed. Valve 20 actuated by rod 17 and the lifter mechanism of valve 3, is operated and the delivery of the compressor is stopped. If the pressure in vessel 7 drops below a pre-set level, regulator 12 causes the servo to speed up the engine and compressor by displacing rod 17, and valve 3 is closed so that the delivery pressure again increases. The switch 16 may be replaced by a slide-valve, or by an electric switch.
