ARRANGEMENT WITH AN ENCAPSULATING HOUSING

摘要

An arrangement with an encapsulating housing comprises a first tube section (2) and a second tube section (3). The tube sections (2, 3) may move relative to each other and at least partly define a variable encapsulation volume (12). A duct (11) connects the encapsulation volume (12) to a compensation volume (13). A volume change in the encapsulation volume (12) brings about a reciprocal proportional change in the compensation volume (13). A pressure equalisation can thus be carried out on a relative movement of the tube sections.
