Indirect-movement mixing cartridge (100, 400) with flow-rate limiter, comprising: - a cartridge body (101, 401); - a top element (102, 402) rotatably coupled to the cartridge body, the top element comprising a fulcrum (103, 403) and an actuation lever (104, 404) pivotable about said fulcrum between a forward and a backward position; - a fixed plate (105, 405) provided within the cartridge body and comprising openings for the separate inflow of hot and cold water and with an opening for the outflow of mixed water; and - a movable element (106, 406) provided within the cartridge body and comprising a second plate (107, 407) that internally defines a mixing chamber, the movable element being rotatably coupled to an end (108, 408) of the actuation lever (104, 404) and slidably coupled to a lug provided in the internal surface of the cartridge body, so that: a) when the actuation lever (104, 404) is in its forward position, a rotation of the top element (102, 402) about its axis (A, A') does not rotate the movable element (106, 406) on the fixed plate (105, 405), the movable element remaining at a first position in which there is no outflow of mixed water; and b) by pivoting the actuation lever (104, 404) about the fulcrum (103, 403) towards its backward position, the movable element (106, 406) is displaced on the fixed plate (105, 405) from said first position to a second position in which there is a maximum outflow of mixed water, said second position being dependent on the relative rotation angle of the top element with respect to the cartridge body, hence defining a locus of second positions; characterized in that the indirect-movement mixing cartridge (100, 400) further comprises a flow-rate limiter (109, 409) to limit, for each relative rotation angle of the top element (102, 402) with respect to the cartridge body (101, 401), the displacement of the movable element (106, 406) to an intermediate position located between said first position and a second position of said locus of second positions, hence defining a locus of intermediate positions in which the outflow of mixed water is limited to a set value, while the movable element (106, 406) can be displaced beyond the intermediate positions of said locus of intermediate positions against the action of the flow-rate limiter (109, 409); in that the flow-rate limiter (109, 409) comprises a spring-loaded member (110, 410) provided in the movable element (106, 406) and in that the spring-loaded member (110, 410) protrudes from a surface of the movable element (106, 406) towards the top element (102, 402) and a fixed member (111, 411) is provided in the top element (102, 402), wherein the fixed member (111, 411) interferes with the spring-loaded member (110, 410) when the movable element (106, 406) reaches an intermediate position of said locus of intermediate positions; and in that the spring-loaded member (110, 410) and/or the fixed member (111, 411) comprise an arcuate portion (114c, 411a) in a plane perpendicular to the axis (F, F') of rotation of the top element. - a cartridge body (101, 401); - a top element (102, 402) rotatably coupled to the cartridge body, the top element comprising a fulcrum (103, 403) and an actuation lever (104, 404) pivotable about said fulcrum between a forward and a backward position; - a fixed plate (105, 405) provided within the cartridge body and comprising openings for the separate inflow of hot and cold water and with an opening for the outflow of mixed water; and - a movable element (106, 406) provided within the cartridge body and comprising a second plate (107, 407) that internally defines a mixing chamber, the movable element being rotatably coupled to an end (108, 408) of the actuation lever (104, 404) and slidably coupled to a lug provided in the internal surface of the cartridge body, so that: a) when the actuation lever (104, 404) is in its forward position, a rotation of the top element (102, 402) about its axis (A, A') does not rotate the movable element (106, 406) on the fixed plate (105, 405), the movable element remaining at a first position in which there is no outflow of mixed water; and b) by pivoting the actuation lever (104, 404) about the fulcrum (103, 403) towards its backward position, the movable element (106, 406) is displaced on the fixed plate (105, 405) from said first position to a second position in which there is a maximum outflow of mixed water, said second position being dependent on the relative rotation angle of the top element with respect to the cartridge body, hence defining a locus of second positions; a) when the actuation lever (104, 404) is in its forward position, a rotation of the top element (102, 402) about its axis (A, A') does not rotate the movable element (106, 406) on the fixed plate (105, 405), the movable element remaining at a first position in which there is no outflow of mixed water; and b) by pivoting the actuation lever (104, 404) about the fulcrum (103, 403) towards its backward position, the movable element (106, 406) is displaced on the fixed plate (105, 405) from said first position to a second position in which there is a maximum outflow of mixed water, said second position being dependent on the relative rotation angle of the top element with respect to the cartridge body, hence defining a locus of second positions;
