A second operating chamber (25) on the side of the control motor (22) remote from the control element (23) has a suction tube connection (35). A control spring (43) stronger than a restoring spring (39) and connected to the control motor housing (44) and control element is tensioned in the direction of the first operating chamber (24). ADVANTAGE - More compact.
