DEVICE FOR CONTROLLING OR REGULATING THE FLOW RATE AND/OR FLOW DIRECTION OF FLUIDS.

摘要

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). 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). According to one aspect, the invention relates to an optical security component (10) intended to be observed in reflection in an inspection spectral band from an inspection side (100), the component comprising: a set of layers that are transparent in said inspection spectral band, one layer of which is structured, said structured layer comprising, in one or more inspection zones (A, B) forming recognisable graphic elements, microstructures suitable for generating variable visual effects that vary depending on the conditions of illumination and/or observation of the component, and on the periphery of said inspection zones, microstructures the shape, spatial distribution and lateral and heightwise dimensions of which are random in order to form a structure (D) that is optically scattering in the inspection spectral band; and a metal layer (15) arranged locally on the structured layer, such as to have a maximum reflection in the inspection zones and a transparency that increases level with the optically scattering structure, the transparency increasing with distance from the inspection zones.
