Abstract

A pressure fluid reservoir is made from two housing components, that are brought together with an outer and inner thread arrangement with end stops formed by adjacent ends of the two housing components. The first housing component of the pressure fluid reservoir includes two segments and the second housing component includes two guide faces with an inner thread and an outer thread located between them. The guide faces are disposed with such a length and such a spacing with respect to one another that prior to the threads being screwed together during assembly, the threads are sealed off from the reservoir chambers and two stop faces facing one another on the housing components come into contact on their ends once the screwing operation is completed. The ends are exposed to the outside so that the contact between the ends can be seen from the outside.
