Abstract
Abstract A positioner is disclosed for use in a hydraulic directional control valve of the type having a valve body and a valve spool longitudinally slidable therein. The positioner is a detent mechanism having a resiliently biased, radially operative detent means and a locking-recess means cooperating therewith for releasably locking the spool in its valve spool positions. One embodiment of the recess means is a sleeve having several dissimilar longitudinal series of recesses spaced circumferentially around the sleeve. Either the sleeve or the detent means is positionable at a plurality of angular positions relative to the other so that the detent means may lockingly cooperate with a selected series of recesses. The recesses may be spaced around the exterior of the sleeve, in which case the detent means is spaced outwardly therefrom. Alternatively, the recesses may be spaced around the interior of the sleeve, in which case the detent means is spaced inwardly thereof. This detent mechanism provides standardized structures which can be mounted in several valves where each valve has a dissimilar series of valve functions. The locking-recess sleeve and the detent means are angularly positioned so that the detent means cooperates with the series of recesses on the sleeve corresponding to the valve spool positions of the particular control valve in which it is used. Similar embodiments are also disclosed for use with rotary valves.
