| 摘要 |
The present invention relates to a quick-closing hydraulic coupling consisting of a slave-side (1) and a master-side (2) coupling part which are designed as a plug and socket and can be locked relative to one another in the coupled position by locking means (27, 31) and have in each case one valve (5, 35) guided with the ability to move axially in a housing (3, 21) and interacting in a sealing manner with a valve seat surface (9, 41) of the housing, these valves lying axially opposite and in direct contact with one another in the coupled position. To avoid oil leaks during the coupling operations, the housing (21) of the master-side coupling part (2) is of two-part design, comprising an outer housing part (22) and an inner, axially displaceable sleeve (23). The master-side valve (35) is guided in the sleeve (23) and, on its side facing the slave-side coupling part (1), the sleeve (23) has the valve seat surface (41). The sleeve (23) is arranged so as to be axially displaceable by spring force and, as a result, it rests with its end face on the slave-side coupling part (1) in the coupled position and during the coupling and uncoupling of the coupling parts (1, 2). <IMAGE>
