The change-over device (1) has a housing body (2) with first and second feed channels (3,4), regulated by first and second slides (40,41). Both slides are formed on a common rotary shaft (10), as first and second flat sections (11a,12a), the second section being at a defined angle relative to the first one. The shaft is fitted into a bore of the housing. A shaft section between the flat sections engages tightly on the bore, to seal the two feed channels relative to each other. |
