Abstract
1,031,226. Valves. SOC. DES. CLAPETS T.J. Feb. 27, 1963, No. 7923/63. Heading F2V. A non-return valve with or without a closing spring 15 consists of a closure member 9 with a sealing ring 11 and flexible, depending guides 12 slidable in a bore 5 and formed with claws 13 which limit the opening movement and provide abutments for the spring. The closure member, which is shaped to facilitate flow past the seat 6, may be of moulded synthetic resin and its density, which may be made to approach that of the controlled fluid and chosen to suit a vertical, horizontal or inclined position for the valve, may be determined by the filling of a recess with a light or a heavy material.
