Abstract

1473351 Valves A F WIGLEY 2 July 1975 [5 July 1974] 29811/74 Heading F2V To ensure that a non-return valve functions even when a foreign body is lodged in the valve two separate closure members are provided, acting in series. The first closure member 34, which has a seat 26 on an acetal or metal guide member 22, is formed of a rigid plastics material or metal. The second closure member 36 is of a deformable material and seats on the inner wall of the valve body, which may be of plastics or metal. In an embodiment, Fig. 16 (not shown), two valves of the invention are incorporated in a combined anti-vacuum and non-return valve and in further embodiments, Figs. 17, 18 (not shown), a stop valve is also incorporated.
