The invention relates to a pipe switch with an actuating system, a housing (10) and a closure element (50). The housing comprises an inner wall (12), in which a feed opening (20) and at least two discharge openings (30, 32) are provided. The closure element is arranged between the supply opening and the discharge openings inside the inner wall of the housing. The closure element is pivoted so as to change its position relative to the discharge openings. The actuating system comprises a controller and a drive, the drive being connected to the closure element so as to transmit movement and arranged to alter the position of the closure element. According to the invention, the actuating system is arranged to actuate the closure element in accordance with a plurality of intermediate positions relative to the output openings. A first embodiment provides that the closure element comprises a slide, while a second embodiment provides that the closure element is in two parts and comprises two flaps. Together with the closure element, the actuating system provides that the sum of the cross-sectional areas of the first and second output openings not covered by the closure element is substantially constant in every intermediate position. |
