Abstract

1,248,979. Valves. THOMAS THS SABROE & CO. A/S. 11 Nov., 1968 [16 Nov., 1967], No. 53394/68. Heading F2V. [Also in Divisions G2-G3] A valve usable to control unloading of a refrigerant compressor (see Divisions G2-G3) has a disc 22 supported by a bellows through rods 13, 26 and engaged by leaf springs 29, 30 which cause tilting of the disc, as the bellows expands and contracts, to control flow through nozzle 21. Rotation of housing 11 repositions the plane containing pin 27, 28 to vary the angle of tilt corresponding to a given bellows movement. The nozzle can be located on the left side of the disc. In a modification, the disc is resilient and is attached at a point adjacent its periphery to the bellows housing. In Fig. 3, the disc is hinged at 34 and the nozzle is rotatably adjustable about the axis of shaft 36.
