Abstract

A detent mechanism for a hydraulic control valve, having a detent position in which a detent member is in engagement with a groove and a spring urges the detent member into the groove so that a predetermined force is required to move the detent member out of the groove. A second spring loaded detent member is provided which requires the application of another predetermined force in order to move the mechanism into the detent position. The springs for both of the detent members can be readily changed to adjust the forces required to operate them.
