| 摘要 |
The invention relates to a hydraulic system comprising at least one circulation pump unit (2) that includes a speed controller (4, 26), further comprising at least one hydraulic circuit (A, B) that is connected to the circulation pump unit (2), and at least one mechanical switching device (86, 88; 120, 122; 120", 122") that is pressurized by a fluid in the hydraulic circuit and can be moved into at least two different switched positions; said at least one mechanical switching device (86, 88; 120, 122; 120", 122") can be moved by the circulation pump unit (2) using a hydraulic connection via the fluid, and the speed controller is designed to cause a movement of the switching device (86, 88; 120, 122; 120", 122") by adjusting the speed of the circulation pump unit (2), said speed adjustment generating at least one hydraulic force via the hydraulic circuit, said hydraulic force acting on the switching device (86, 88; 120, 122; 120", 122") and causing the switching device (86, 88; 120, 122; 120", 122") to move. |
