A multipath valve, in particular for medical solutions, has a housing (10) with at least one first inlet (11), one second inlet (17) and one outlet (19), a first flow path being formed between both inlets (11 and 17) and a second flow path between the second inlet (17) and the outlet (19). A non-return valve (15) arranged in the second flow path allows the second flow path to open only in the direction of flow from the second inlet (17) to the outlet (19). To avoid in a reliable manner an incorrect connection between the first inlet (11) and the outlet (19) leading to the patient, an adjustable valve body (13, 13') is mounted in the housing (10) in such a way that it can be moved form a first position, where it opens the first flow path, into a second position, where it opens the second flow path, and vice-versa, at the same blocking the other flow path. The adjustment of the valve body (13, 13') is automatically effected by the instantaneous differential pressure in both inlets (11 and 12). |
