Summary:1388422 Valves STANADYNE Inc and A M MOEN 26 May 1972 [27 May 1971] 25106/72 Heading F2V A fluid valve, e.g. a rotary valve, comprises a valve member 20, Fig. 1, movable within a sleeve 16 enclosed in a housing 10. The valve includes a seal having at least one port seal portion 62 which extends through a sleeve port 30 and sealingly contacts the valve member, and a body portion 54 which is at least partly cylindrical about the valve member axis and is integral with the port seal portion. The body portion 54 defines an annular chamber 70 with the housing or sleeve, which chamber can be used for receiving the fluid which thereby exerts a force on seal in a direction urging the port seal portion towards the valve member, or for allowing the seal to distort when its port seal portion is otherwise urged by the fluid towards the valve member. The housing has inlets 34, 36 and an outlet 40. The seal shown comprises two identical semi-cylindrical elements 50, 52 each provided with fixing beads 58, an annular sealing bead 68 coaxial with portion 62, and a sealing bead 66 around the perimeter of the element. Another sealing bead may be located adjacent the sealing bead 66. All sealing beads may be omitted, Figs. 8 and 9 (not shown). In the two-way valve shown in Fig. 10, the seal 146 is arcuate to conform to the surface of sleeve 142 and has a part-conical external surface to conform to the conical inner surface of housing 130.
