| 摘要 |
The invention concerns a hydraulic system comprising at least one hydraulic drive means ( 1 ), a conduit system ( 10 ) connected to the hydraulic drive means for conveying hydraulic liquid to and from the hydraulic drive means, where the conduit system comprises a conduit circuit ( 11 ) containing hydraulic liquid, connected to the hydraulic drive means, a pump ( 12 ) for generating a flow of hydraulic fluid in the conduit system and a motor ( 13 ) to power the pump. The pump ( 12 ) is arranged to control the flow of hydraulic liquid in said circuit ( 11 ), and the hydraulic drive means ( 1 ) is controllable substantially only by controlling the flow of hydraulic liquid in said circuit ( 11 ) by means of the pump ( 12 ).
