A device (1) for controlling or regulating the flow rate and/or flow direction of fluids is shown and described, said device comprising: a housing (2) having at least two inlets (3) and/or outlets (4a, 4b, 4a', 4b', 4c), at least one arm (8, 8', 8'') which is movably arranged inside the housing (2), and at least one closure element (10a, 10b, 10a', 10b', 10c) which is arranged inside the housing (2) and is movably connected to the arm (8, 8', 8''), wherein the arm (8, 8', 8'') and the closure element (10a, 10b, 10a', 10b', 10c) connected thereto are arranged and connected to one another in such a way that at least one inlet (3) and/or outlet (4a, 4b, 4a', 4b', 4c) can be shut off by the closure element (10a, 10b, 10a', 10b', 10c), and wherein the closure element (10a, 10b, 10a', 10b', 10c) and/or at least one inlet (3) and/or outlet (4a, 4b, 4a', 4b', 4c) has a curved sealing face (12a, 12b) for sealing off the inlets (3) and/or outlets (4a, 4b, 4a', 4b', 4c). In order to achieve a high degree of mobility of the closure element (10a, 10b, 10a', 10b', 10c) in the loaded state while at the same time having a defined orientation of the closure element (10a, 10b, 10a', 10b', 10c) in the unloaded state, it is proposed to arrange a pretensioned spring element (11a, 11b) between the arm (8, 8', 8'') and the closure element (10a, 10b, 10a', 10b', 10c). |
