<p>A hose-coupling part includes a housing (12) that has a through-penetrating opening, a sealing device (22, 26, 34, 36, and 40) that can be moved axially in the housing such as to seal the through-penetrating opening. The sealing device includes a first member (22) and a second member (26), wherein the first member is placed axially in spaced relationship with the second member and in a non-loaded state is held spaced from said second member by means of a first spring means (34). Because the first member seals against the housing when in an outer end position and because the second member allows a given degree of leakage between the housing and the second member when in its outer end position, there is obtained an equalization in pressure when connecting the hose-coupling part to a co-acting hose-coupling part.</p> |
