HYDRAULIKAGGREGAT FÜR DEN LECKAGEHOHLRAUM EINER PUMPE

摘要

The present invention relates to a hydraulic aggregate for a hydraulic controlling and/or regulating device, including a pump having a pump housing that includes a leakage chamber with a leakage bore opening into a hollow space of a lid fixed to the pump housing, said hollow space having a pressure-fluid connection to the atmosphere. The leakage bore is connected to the atmosphere by way of a float valve open in its basic position, and the float valve effects closure of the leakage bore under the effect of hydrostatic pressure in lid.
