摘要

A system which is closed to the outside atmosphere is fitted to the hydraulic brake system and contains a movable pressure compensating vessel(1,2). The inner gas atmosphere consists of an inert gas(3) such as nitrogen. Two valves are fitted for gas filling or oil replenishment. A vessel with brake oil with brake oil is fitted on the inlet pipe connection and the brake oil can be filled up to a mark on the reservoir(6).
