Abstract
The invention sets forth a hydraulic housing block with a downward-opening cavity which is covered by a protective cap. For ventilation of the cavity, the protective cap is arranged with a clearance relative to the hydraulic housing block. The protective cap is arranged in such a way that spray and dirt can not penetrate into the cavity through a gap between the protective cap and the hydraulic housing block. In order to prevent this penetration, the cap seals off the cavity by at least one encircling sealing lip and provides an opening at the lowest point on the circumference of the sealing lip to allow ventilation of the cavity.
