Abstract

1347770 Spray nozzle RIV-SKF OFFICINE DE VILLAR PEROSA SpA 29 Nov 1971 [29 Dec 1970] 55333/71 Heading B2F [Also in Divisions C7 and F4] A nozzle used to quench heat treated metal rings with oil consists of a cylindrical casing 50 defining an internal chamber 51 and having a second cylindrical casing 53 spaced from the casing 50 by an annular element 56, the oil being passed through the intermediate annular spaces 55a, 55b to produce two annular jets 42a, 42b the diameter of which correspond to the internal and external diameters of the ring. A conduit 58 allows for the escape of oil vapours formed in the spraying zone.
