摘要

The clutch (10) has a plug portion (20) which is connected to a hydraulic system, where an actuating element (60) is provided in a housing (11) of the clutch such that a sleeve valve (41) is brought into an opening condition in the coupling of a system connector with a sleeve portion (40). A system valve stays in a closed condition. The actuating element allows a pressure increase in the sleeve portion, where a fluid is flowed by the hydraulic system in the sleeve portion. Independent claims are included for the following: (1) a method for releasing a hydraulic line of a hydraulic system with a clutch; and (2) a method for operating a releasing system.
