Abstract
A hydraulic remote control (HRC) valve including a main spool valve and a pilot pressure control valve. A lever is operatively connected to the pilot valve whereby to provide “finger tip” control of the main spool valve. The HRC has an inverting output, whereby movement of the lever away from a neutral position causes a decrease in hydraulic pressure supplied to a hydraulic clutch. In practice, two HRC's according to the invention are embodied in a single housing. The HRC of the invention is of use in controlling the hydraulic steering clutches of tracked vehicles.
