Abstract
The invention relates to a hydraulic unit for a hydraulic control and/or regulating device, in particular for anti-blocking and/or anti-slipping brake systems, comprising control and regulating electronics arranged in a control housing as well as a valve block connected to said control housing, whereby at least one driving means is provided for at least one pressure-generating element. A cavity associated with the pressure-generating element receives leakage fluid from the pressure-generating element and a discharge channel that is connected to the cavity is provided in the valve block. According to the present invention, a means is associated with the discharge channel, and said means prevents fluid from entering into the discharge channel.
