Charge Pressure Reduction Circuit For Improved Transmission Efficiency |
摘要 |
A charge pressure reduction circuit for a loader backhoe in which a directional control valve causes the charge pump to operate at a system pressure high enough to adequately supply a clutch circuit when conditions indicate the vehicle is operating in a loader or transport mode. The directional control valve causes the charge pump to operate at a lower pressure as, for example, required for a lubrication circuit when conditions indicate the vehicle is in a backhoe operating mode. |
