A decoupling device for separating a motor from a powertrain, having a piston which is movably mounted in a housing parallel to a longitudinal axis L of the housing and which has an arm for directly or indirectly actuating a coupling element. A first region of the piston is operatively connected to a first pressure chamber such that when pressure is applied to the first pressure chamber, the piston is moved in a first direction parallel to the longitudinal axis L. A second pressure chamber is provided which is operatively connected to a second region of the piston such that when pressure is applied to the second pressure chamber, the piston is moved in a second direction parallel to the longitudinal axis L, the second direction being opposite the first direction.

A clutch for selectively coupling a motor to a motor vehicle drive train includes a housing, a shift sleeve, an actuating bell arranged to move the shift sleeve, a piston and a stop disc. The housing includes a first pressure chamber and a second pressure chamber. The piston is connected to the actuating bell and arranged in a pressure-dependent axially movable manner between the first pressure chamber and the second pressure chamber. The stop disc is arranged in the first pressure chamber or in the second pressure chamber for limiting axial mobility of the piston.

Clutch with a piston that can be acted upon from both sides, and stop plate

A hydraulic system, especially for motor vehicles includes a master cylinder, a slave cylinder and a pressure medium line connected thereto. The invention provides a hydraulic system which is simple or economical to produce by virtue of the fact that the hydraulic system includes at least one hydraulic plug-type connection with a plug connector and a socket contact and the plug connector includes an abutment and a sealing element which are made of different materials and which are connected together in a material fit.
