A manual override handle assembly for the operation of a hydraulic control valve of the type having a movable spool includes a housing forming a hollow chamber in which a spool extension is slidably mounted. A handle assembly extends outwardly from the housing and is mounted for pivotal movement within the chamber. The handle is movable to an inoperable position wherein the handle is disassociated from the spool extension so that movement of the spool extension will not result in movement of the handle. The handle is further movable to an operable position wherein the handle engages the spool extension so that movement of the handle results in movement of the spool extension.

DETAILED DESCRIPTION In accordance with one aspect of the invention, a manual override handle is mounted for pivoting motion on a plurality of axes fixed with respect to the housing of a control valve containing a movable valve spool, the handle being manually movable to and from a position at which it is operatively connected with the valve spool for actuation of the same between working and/or non-working positions.
In accordance with another aspect of the invention, the spool extension includes camming surfaces that automatically place the handle into a position corresponding to the position of the control valve spool when the handle is moved from its inoperative to its operative position.
