<p>A hydraulic pressure control is for a utility vehicle the which anciliary equipment is driven by the hydraulic conduit. It has the pump provided with a shunt back to the inlet when the equipment is not being used. The prevent the hydraulic circuit from overheating and reduces the tonque loss in the pump. The system is designed for hydraulic circuits which are driven directly off the vehicle engine. The shunt is operated by a control valve controlled by engine speed, or simply torque demand on the hydraulics. The control can be applied to dual hydraulic circuits with both high pressure lines shunted to the common in take of the pump.</p> |
