Abstract

606,620. Slide valves. FAIREY AVIATION CO., Ltd., and BISHOP, J. W. Jan. 24, 1946, Nos. 2390 and 12841. [Class 135] A hydraulic slide valve comprises a casing with two opposed interior faces, one face having an inlet port 14 and the other two outlet ports 15, 16, and a slide comprising two telescopic parts 22, 23, each formed with an aperture 25 or 26 surrounded by a circular land 22c or 23c, the areas on which the inlet pressure acts being so arranged that the inlet pressure presses the two parts 22, 23 away from one another into sealing engagement with the two faces of the casing. The latter are formed on end plugs 12, 13 closing the main casing 10. The two valve parts comprise discs 22, 23 with interengagihg flanges 22b, 23b surrounded by a ring 21 connected at opposite points to a guide rod 14 and an operating rod 20 in bearings 17, 18 respectively. The land 22c surrounds the inlet port 14 for all positions of the slide and the land 23c closes both the ports 15, 16 in the central position of the slide and opens one or other of them to the inlet pressure on movement away from the central position. The discs 22, 23 are also pressed apart by a spring 24. In a modification, the inner edges of the lands have annular recesses filled with relatively soft metal such as solder.
