Abstract

1418750 Valves M PICHON 14 March 1973 [24 March 1972] 12384/73 Heading F2V [Also in Division F1] In a pump for viscous material, e.g. concrete, flow between an inlet 6, a pumping cylinder 2 and an outlet 3 is controlled by an oscillatable shutter valve 5 attached in cantilever fashion to a shaft 8, an end plate 9 of the valve chamber being removable with the valve assembly for maintenance. As shown, shaft 8 is supported by a pulley 15 with a tyre 16 engaging extension 9a of plate 9, a seal 11 being adjustably compressed by a plate 12 with bolts 13 reached via pulley aperture 15a, and lubricated via a nipple 14. The valve may be operated by a double-acting jack connected at 18. In Figs. 3 and 4 (not shown), the valve shaft is supported by spaced bearings (22<SP>1</SP>), (23) in the plate extension, a pinion (25) being fixed to the shaft between the bearings and operated by a rack (26) to operate the valve, the shaft seal being compressed by a threaded member (27) reached through an aperture in the plate extension.
