Abstract
The present invention relates to a hydraulic unit, in particular for slip-controlled automotive vehicle brake systems, including a pump and an electric motor for driving the pump, wherein the drive of the electric motor extends into a crank chamber of the pump, and including ventilation and venting of the crank chamber for the purpose of pressure compensation in relation to the atmosphere using a pressure compensation channel. The pressure compensation channel is connectable to the atmosphere by way of inlet and outlet valves which are closed in their basic position and responsive to the pressure differential.
