A valve closure member 7 for a pressure controller of the fuel spill valve type as in GB 2,013,838 A has a part-spherical portion 72 to allow relative rotation between the member 7 and a support member (8, Figure 1, not shown), a plane sealing surface 73 and a cylindrical part 74 to support a biasing spring. A blind bore 76 is disposed coaxially within the member 7 and a cylindrical tailpiece 70 is provided on the opposite face. The arrangement allows the closure member to be produced from low stock and to allow the valve to be assembled easily. <IMAGE> |
