Task

The proportional valve (Y151) is connected to the vehicle's compressed-air system's consumer circuit. As soon as an electrical input signal is picked up by the turbo clutch control unit (TK) (A125), a pneumatic actuating pressure that matches the electrical input signal is actuated for the oil reservoir chamber of the turbo clutch.
