A hydraulic control, for example of a hydraulically operable working tool, includes a hydroconsumer that can be acted upon against a permanent force via a pressure source, and a switching valve with working power/pressure control function reacting against a spring force depending on a pressure and/or through flow volume. The switching valve connects the hydroconsumer with a tank for a return stroke of the hydroconsumer when the pressure source is switched off. The hydroconsumer can be hydraulically stopped with the return stroke via the pressure source by a pressure pulse and/or through flow volume pulse. In a hydraulically operable working tool, the hydroconsumer can be hydraulically stopped in the return stroke even before a predetermined end position is reached by switching on the pressure source. |
