Abstract

703,047. Rotary compressors or pumps. U.B.I. SOC. PER AZIONI (UTILIZZO BREVETTI INDUSTRIALI). May 14, 1952 [June 11, 1951; March 20, 1952], No. 12190/52. Class 110 (2) The casing bore of a sliding-vane compressor or pump is formed of two arcs of circles with radii 30, 31, their centres being as shown in Fig. 2, the two arcs joining at the points 32, 33. The vanes 17, shaped as shown, are controlled by blocks 18, on a pin 19, which slide through annular grooves 26, 37 in end cheeks 3, 8 of tempered steel. The distance apart of a pair of vanes is adjusted by means of a sleeve 48, spring 45, and a plunger 50. In the delivery channel 35 is provided a combined silencer and oil separator 56, the compressed fluid passing through a duct 36 into a second oil separator containing a baffle 10. Separated oil passes to a reservoir 33, under fluid pressure which forces the oil to circulate again, for lubricating and sealing purposes, through ducts 54, 51, 47 leading to the working parts.
