| 摘要 |
The circuit (C) has a pump controller (5) for controlling displacement of a hydraulic pump (1) e.g. axial-piston pump, with variable displacement, fed by a fuel pump (2). The pump controller is designed as an actuator with double-acting chambers (52), where one of the chambers is connected to the fuel pump. The other chamber is connected to the fuel pump via a calibration line comprising a proportional pressure reducer (21) for controlling proportional displacement of the pump with variable displacement. |
