SELECTOR VALVE |
摘要 |
<p>A selector valve (10) for providing a plurality of fluid signals has a plurality of signal ports (17-22) and a pair of drain ports (23,24) opening into a bore (14) of a body (11) and are angularly spaced one from another in a plane normal to the axis of the bore (14). A spool (12) is reciprocatable within the bore (14) between a plurality of positions. At each position at least one of a plurality of radial passages (48-57) in the spool (12) communicates an inlet passage (25) with a manifold (41), another of the radial passages communicates the manifold (41) with one of the signal ports (17-22) and one or more of a plurality of arcuate pockets (60-68) in the spool (12) communicate the other signal ports (17-22) with the drain ports (23,24). By angularly spacing the signal ports (17-22) and positioning the radial passages (48-57) in the spool (12 ) for selective communication with the signal ports (17-22) at the various positions on the spool (12), a plurality of signals can be obtained with a relatively short travel distance of the spool (12).</p> |
