| 摘要 |
The invention relates to a coupling for equalizing variations in the volume flow of a hydraulic engine, the hydraulic engine (M) comprising at least one periodically operated displacement chamber (4) and being arranged to suck pressurized medium into this displacement chamber (4) from the suction side (T) of the hydraulic engine, to compress the pressurized medium sucked into the displacement chamber (4) to a working pressure and to supply the compressed pressurized medium out from the displacement chamber (4) to the pressure side (P) of the hydraulic engine. For damping of variation caused by the compression, the coupling is arranged to supply pressurized medium into the chamber (4), to compress the pressurized medium sucked into this displacement chamber (4). |
