<p>Test device for simultaneously testing at least two hydraulic systems, each containing a positive-displacement pump (4a,4b) and a hydraulic-medium reservoir (8a,8b), which test device has its own positive-displacement pump (16) whose low-pressure side is connected via individual regulators (22a,22b) to the respective low-pressure sides of the systems to be tested and whose high-pressure side is connected to the respective high-pressure sides of the systems to be tested, and which has means for observing the respective filling levels which deliver signals which represent the instantaneous filling level and are fed to a comparator (32) to determine at least the highest filling level, while in response to said determination, the regulator (22a,22b) connected to the reservoir (8a,8b) having the highest filling level is controlled in such a way that its passage size is increased. <IMAGE></p> |
