Abstract
A selectable detent relief valve of this invention is used to operate a hydraulic detent mechanism on a manually operated spool valve. This design has three modes of operation, no-detent, continuous detent and kick-out detent. The no-detent position allows flow to pass through the relief valve, from a first port to a second port and bypass the relief function. The pressure created, disengages the detent mechanism in the spool valve. The spool always returns to neutral position as long as pressure is present. The continuous detent position blocks the flow from a first port to a second port. The kick-out detent position allows flow to pass from the first port to the second port to override (kick-out) the detent mechanism in the spool when the pressure is greater than 2600 psi.
