Abstract
1,230,887. Valves. I.V. PRESSURE CONTROLLERS Ltd. 27 Jan., 1970 [6 Feb., 1969; 23 May, 1969], Nos. 6579/69 and 26569/69 Heading F2V. In a spool-type selector valve, the spool shaft 12 has assembled thereon a plurality of spool parts 16, 17 and 18, with annular washer type seals 19 being anchored between each two adjacent spool parts. The seals are made of plastics or elastomeric material, and they may be in the form of plain washers or may be pre-formed to a shape such as that shown in the drawing. In addition, the seals are made to project from the outermost periphery of the assembled spool 11 such that, for example, any fluid tending to flow between valve ports 14 and 15 urges the righthand seal, as seen in the drawing, into sealing engagement with the valve bore and so prevents such leakage. In modifications (Figs. 2, 3 and 4, not shown), annular 0-rings may be provided on either side of each seal and circumadjacent its innermost periphery, i.e. in engagement with the shaft 12. Furthermore, only one seal 19 may be provided between each pair of valve ports 14, 15, or, when two such seals are provided, the sealanchoring portions of the spool parts may be shaped to enhance the anchorage and to allow greater flexing of the seals.
