| 摘要 |
The stage mechanism is mechanically coupled to at least one speed-controlled hydraulic motor (10, 110) of infinitely variable working volume and two directions of flow, for example by means of a transmission (11) or a transmission section (9). In this case, the hydraulic motor (10, 110) is connected by means of a high-pressure line (15) to the high-pressure connection of at least one hydraulic pump (21) with a single direction of flow. The high-pressure line (15) is connected to a high-pressure accumulator (27). The hydraulic pump (21) may be connected on the input side and the hydraulic motor (10, 110) may be connected on the output side to a low-pressure line (16) supplied by a feed pump (29). <IMAGE>
