Abstract

650,100. Stuffing-box substitutes. AALBORG VAERFT AKTIESELSKAB, and BLACHE, H. H. Aug. 22, 1947, Nos. 23281 and 23282. Convention dates, May 26, 1945 and April 25 1946. '[Class 122(v)] [Also in Group XXXIII] In an hydraulically-operated mechanism for a variable pitch propeller in which the hydraulic cylinder rotates with the propeller shafting and pressure liquid is supplied to, and exhausted from, the hydraulic cylinder through annular chambers having rotating side walls and a non-rotating outer circumferential wall (see Group XXXIII), leakage from the chambers is prevented by sealing rings in the outer wall co-operating with the side walls, the outer wall being mounted so that it can move axially with and radially to the side walls and having an elastic supply conduit thereto. As shown, double seal type rings 56, 57 resiliently engage the inner circumference of a housing 55 constituting the outer wall of an annular chamber 58 and are urged against the rotating end walls 53, 54 by spiral springs 59 compressed between recesses 60 in an internal flange 61 of the housing 55 and recesses 62 in rings 63, 64 which are axially movable relative to the housing but held against rotation by pins 65 engaging recesses in the flange 61 and in the rings 63, 64.
