Abstract

940,150. Prepayment gas meters. UNITED GAS INDUSTRIES Ltd. Feb. 16, 1962 [Feb. 18, 1961], No. 6075/61. Addition to 939, 662. Heading G4V. [Also in Division F2] A shutoff or inlet valve assembly for prepayment gas meters comprises a resilient valve pad 5 coacting with a seat 7 and secured between a disc 1 and washer 6 by a cylindrical body 2 which is formed with a conical or spherical seating 10 for the spherical head 13 of a spindle 11 by which the disc is universally mounted on an operating arm 12. The disc 1 carries a resilient annulus 20 through which, after the valve pad 5 has seated, a restricted flow is permitted, passing by way of a channel &c. in the surface of the head 13 and/or the surface 10 and an orifice 17, until a disc 19 on the arm 12 is brought into engagement with the annulus 20. The secondary valve, instead of being constituted by the parts 19, 20 may consist of a resilient washer carried by an extension of the spindle 11 and coacting with the orifice 17, or an extension of the spindle 11 may be shaped to coact with a resilient annulus concentric with the orifice 17. A loading spring 15 for the head 13 may be of conical form.
