ABSTRACT:
A reversing slide valve for a hydraulic motor is operated by a pilot slide in a common valve body with the main slide, the latter being biased toward an intermediate position by springs and entraining the pilot slide when moving from the intermediate to either terminal position. Friction rings prevent movement of the pilot slide with the main slide when the latter returns to its normal intermediate position under spring bias. The pilot slide directs pressure fluid to compartments in the valve body partly bounded by end faces of the main slide in such a manner that the main slide is moved from its intermediate position into the terminal position remote from the last-occupied terminal position whenever pressure fluid is supplied to the valve after an interruption of fluid supply.
