Abstract
In a coupling for a drive device, such as an internal combustion engine, a rotor and an entraining disc are connected. The entraining disc is movable relative to a drive disc so that it can be selectively coupled with the drive disc. A housing at least partly encloses the drive disc and supports a pressure chamber adjacent the entraining disc. The pressure chamber includes a movable cover interconnected with the entraining disc. By regulating the pressure within the chamber, the entraining disc can be coupled or decoupled relative to the drive disc. When coupled to the drive disc, the entraining disc drives the rotor.
