Abstract
618,502. Valves for gas meters. CHELTEN. HAM METERS, Ltd., PORTER, J., and TAYLOR, H. Oct. 25, 1945, No. 28210. [Classes 54 and 135] A valve for a dry gas-meter comprising a seating a, Fig. 1, and a cap b rotated by the meter mechanism, has at least that part of the cap or seating which coacts with the seating or cap, respectively, made from a material having an inherent lubricating property, e.g. graphite. The seating comprises concentric rings c, d, Fig. 4, interconnected by radial ribs e forming a plurality of ports. The cap, of which Fig. 3 is an inverted plan, has an inlet port i, and a chamber g by which the central port in the seating is placed sequentially in communication with the other ports. Either the seating or the cap is made wholly of graphite, or the cap may be made with a graphite facing. The part, i.e. the seating of the cap, not made wholly or in part of graphite may be made wholly of a metal having a low coefficient of friction, e.g. an antimony-tin alloy. The edges of the seating with which the cap co-operates are made as narrow as practicable, e.g. <1>/32 to 1/16 inch.
