ABSTRACT:
A hydraulic unit for a hydraulic regulation device, in particular for slip-controlled motor vehicle brake systems, includes several hydraulic, mechanical and/or electrically operable functional elements arranged at an accommodating member, such as accumulation elements, valve elements, pressure-generation and driving elements, and including at least one cavity associated with at least one functional element. Two connecting channels that lead into the atmosphere are provided with closing devices, which hinder the ingress of fluid into the cavity and allow ventilation of the cavity and a discharge of leakage fluid into the atmosphere. The invention permits an automatic bleeding and an automatic removal of leakage fluid independently of the spatial arrangement of the unit.
