Abstract

1,069,855. Valves. AUDCO Ltd. Oct. 13, 1964, No. 41798/64. Addition to 940,222. Heading F2V. A frusto-conical seat 13 is closed by engagement with a frusto-conical closure surface 16 and sealing element 17 of a closure assembly 14 which is resiliently mounted upon an enclosed cylinder 19, by a spring washer 23, for operative displacement therewith upon a guide rod 18 by means of pressure fluid introduced, via guide rod passages 34, 36 and 35, 37, to the interior of the cylinder 19 respectively above and below a piston 24 which is mounted in sealing engagement upon rod 18, with displacement thereupon limited by circlips 27 and member 28 abutting circlip 29, and is in sealing contact with the cylinder 19. The seated closure is locked in position by a series of balls (33) (Figs. 2-4, not shown) which engage between the cylindrical surface of a ring (30), carried upon bolts (31) dependent from piston 24, and a frusto-conical shoulder (21a) of cylinder 19 and is unlocked by displacement of the balls (33) radially inwardly into contact with frusto-conical shoulder 30a and cylindrical skirt (30b) of the ring (30) as the piston 24 is displaced upwardly, carrying the ring (30), into contact with circlip 27 by fluid pressure admitted via the passages 35, 37. The cylindrical skirt (30b) of the ring is of sufficient length to prevent displacement of the balls (33) under the ring (30) and, in alternative embodiments, may be omitted and the function thereof performed by a washer (138) (Figs. 5 and 6, not shown) loaded into contact with the ring (130) by a spring which is seated on the member (128) abutting circlip 29, or by the ring (230) (Figs. 7 and 8, not shown) extending as a cylindrical skirt with a frusto-conical shoulder (230a) at the end thereof in sliding contact over a raised cylindrical portion of the member (228) which abuts circlip 29.
