Abstract: A flow rate regulator (1) having a regulator housing (2), wherein said regulator housing (2) has an outer circumferential edge region (5) that can be placed on an end circumferential edge region (3) of a jet regulator (6) and/or of a sieve (11) and including a central annular gap (12), in which an annular throttle body (13) made of elastic material is present, bounding a control gap (15) between same and an inner and/or outer circumferential wall (14) of the annular gap (12) having a control profile, wherein the open flow-through cross-section of said control gap is changeable under the pressure of the flowing water.

Abstract: A sanitary functional unit having a sleeve-shaped insert cartridge insertable into the pipe-shaped fixture outlet of a sanitary outlet fixture is provided. The insert cartridge has a water inlet at the cartridge circumference and a jet former having flow guiding walls oriented transversely to the cartridge longitudinal axis provided in the water outlet. The functional unit deflects the water jet flowing in from the axial direction such that water subsequently flows out of the fixture outlet in a nearly radial direction. The functional unit has a jet former, provided in the region of the water outlet, supporting flow guiding walls that are oriented transversely and perpendicularly to the cartridge longitudinal axis. Since the functional unit is oriented approximately coaxially to the fixture outlet, it also does not project beyond the pipe circumference of the fixture outlet.
