Abstract

A pulsation damper for hydraulic circuits has a housing including a bottom, a casing, and a cover, a damper chamber which is sealed from outside and provided with supply and discharge means for a pressure medium, the housing being composed of two parts so that the bottom and the cover are connected with one another to form a single central element, while the casing peripherally surrounds the central element, the central element, and means forming force-free connecting points between the central element and the cover.
