Abstract: A fluid control circuit for regulating fluid flow between a pressurized fluid source and a hydraulic motor, including a control valve having a movable spool for communicating fluid entering an inlet chamber from the source with service chambers in communication with the motor, a dump valve limiting communication of the inlet chamber with a drain in response to spring means and fluid communicated to the dump valve through a passage open to either of the service chambers when it is placed in communication with the inlet chamber by the control valve spool, the passage otherwise communicating the dump valve with a drain so that fluid communication between the inlet chamber and drain is limited only by the spring means. The force of the spring means may also be varied in certain embodiments of the invention.
