摘要

The control valve (6) and connecting pressure and return flow conduits (7,8,9) for hydraulic fluid works with at least one extra pedal regulating mechanism (10) which via a connection activates the clutch (3). A hydraulic piston cylinder (12) via a pressure conduit (7) is connected to the control valve and via an activation part (11) connected to the clutch, bringing the clutch into action after activation of the extra pedal regulating mechanism. The hydraulic piston cylinder can be adjustably activated by a spring or a pressure container and has a component (14) which permits movement of the cylinder piston connecting rod (15) with free passage between it and the clutch.
