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).

A cartridge valve includes a housing, a stem adapter, and a stem assembly. The stem adapter includes a body defining a first hole, which extends in a longitudinal direction. The stem assembly includes a first stem component and a second stem component. The first stem component includes an arm and a spherical portion that is configured to be at least partially positioned within the first hole and defines an opening. The second stem component has a body that is configured to be at least partially received within the opening of the first stem component. The spherical portion is configured to expand in size in response to the first end inserting a portion of the body of the second stem component into the opening in the first stem component, which increases a frictional resistance induced by relative rotation between the stem assembly and the stem adapter.

A cartridge valve for a faucet that includes a housing; a stem adapter at least partially received in the housing and comprising a body defining a slotted hole, which extends in a longitudinal direction, and a threaded hole, which extends in a radial direction; a stem received in the slotted hole and having a central portion that defines a threaded hole; and a screw threaded to the threaded hole of the stem and the threaded hole of the stem adapter to rotatably couple the stem to the stem adapter at a first predetermined frictional resistance in response to rotation of the stem relative to the stem adapter.

A single control mixer valve structure for taps and fittings comprising a fixed disk provided with an outlet port and two ports, respectively, one for the hot water and the other for the cold water that come from two inlet openings, formed in a base, mounted in which is the fixed disk on which a mobile disk mounted in a mobile-disk holder is able to slide; the mobile-disk holder and the mobile disk define a mixing opening, which is adapted to connect the inlet openings with an outlet opening, formed in the base, in a position corresponding to the outlet hole on the fixed disk, from which the mixed water flows out; sliding of the mobile disk on the fixed disk causes partial opening or complete closing of one or both of the ports of the fixed disk, thus adjusting the amount of hot water and cold water that passes from the inlet openings to the outlet opening for the mixed water; the mixer valve structure is characterised in that the mobile-disk holder has, on the side facing the fixed disk, a body that is closed or is provided with one or more cavities and is configured so as to reduce the useful area of passage of the mixing opening.

The mixing cartridge comprises: a cartridge body (1); an actuation lever (5) a fixed plate (2) placed within the cartridge body (1) and comprising inflow input openings and an output opening for the outflow of mixed water; and a movable element comprising a movable plate (4) provided within the cartridge body, coupled to the actuation lever to be moved on or with respect to the fixed plate and internally defining a mixing chamber (41) open towards the fixed plate and which selectively communicates or blocks the communication of said input openings with the output opening. The mixing cartridge comprises a flow rate limiting arrangement placed within the cartridge body in the path followed by the water flow between said inflows and said outflow, so that the flow rate of said water is limited.
