Abstract: A sanitary fitting (1) that contains a fitting body (2), a first spray plate (3), a second spray plate (4), and a two-way valve (5), which can be used to selectively route a liquid to the first spray plate (3) or to the second spray plate (4), wherein the two-way valve (5) is arranged in the fitting body (2) and having a valve body (6), which is mounted rotatably about an axis of rotation (11) in a valve housing (25) of the two-way valve (5) between a first valve seat (7) of a first outlet (8) of the two-way valve (5) and a second valve seat (9) of a second outlet (10) of the two-way valve (5).

Abstract: A single-lever cartridge for a sanitary faucet for adjusting the temperature and/or quantity of mixed water by means of a swivel lever (3), having a control disk arrangement (5), which has a stationary control disk (6) disposed in a stationary position in the cartridge, in which a cold-water inlet and a hot-water inlet (27, 29) and a mixed-water outlet (31) are formed, and a dynamic control disk (8) displaceable by means of the swivel lever (3), in which a recess (33) is formed, which is disposed in different overlaps with the cold-water inlets and hot-water inlets (29, 27) and the mixed-water outlet (31) to adjust the temperature and/or quantity of the mixed water fed from the mixed-water outlet (31) of the stationary control disk (6), wherein the two control disks (6, 8) are in sliding contact with sealing surfaces (35, 37) facing each other at a sealing plane (DE), and wherein the mouths (39) of the cold-water inlets and hot-water inlets (29, 27) are formed in the sealing surface (35) of the stationary control disk (6), which mouths can be covered by the sealing surface (37) of the dynamic control disk (8). According to the invention, the cartridge has a throttling element (41) designed as a separate component, which can be used to reduce a flow cross-section of the mouths (39) of the cold-water inlets and the hot-water inlets (29, 27), for throttling the hot-water flow and/or cold-water flow into the recess (33) of the dynamic control disk (37).

Abstract: The invention relates to a mixing cartridge (1) for generating mixed water with a mixing temperature, having a hot water inlet (2) for hot water, having a cold water inlet (3) for cold water, having a mixing chamber (4), in which the hot and cold water can be mixed, and having a mixed water outlet (5) through which the mixed water can leave the mixing cartridge (1). According to the invention, the mixing cartridge (1) has at least one vortex element (6), which is arranged and/or designed in such a way that the water flowing through the mixing cartridge in a flow direction can be made to rotate, such that the water can form a water vortex.
