Abstract

1,117,372. Regulating compressors. HOERBIGER VENTILWERKE A.G. March 22, 1966 [March 24, 1965], No.12581/66. Heading F1N. In an infinitely variable delivery volume control for piston compressors acting by retarding the closing of the automatic suction valve 6 by varying the force holding the valve open by means of a plurality of lifting pins 12 loaded by springs 14 bearing against a movable pressure plate 15, the lifting pins 12 are provided with detachable weights 23, 24 for the purpose of varying the effective masses of the pins to suit the operating conditions of the compressor. The pressure plate 15 has a bush 17 slidable on a guide 18 and is urged towards the valve 6 against the action of a return spring 21 by a pushrod 19 operated by a hydraulic or pneumatic cylinder. The detachable weights may be in the form of rings or sleeves having bores provided with inwardly directed collars on which the caps 13 of the pins 12 seat. In an alternative arrangement the pins pass through clearance holes in the pressure plate 15 and carry the rings above the pressure plate with or without the interposition of an elastic damping element such as a cup spring or rubber washer.
