Ventilation device, for hydraulic power steering in vehicles, has pressure-less inner region of steering gear connected through pipeline to closed container communicating with atmosphere

摘要

At least a pressure-less inner region (54) of the steering gear (10) is connected through a pipeline (58) to a substantially closed container (42) which communicates with the atmosphere. The container is preferably the supply container of the hydraulic power steering unit and the pipeline opens into the container at a geodetically upper area.
