Problems solved by technology

Since the screwdriver can barely fill the gap-like recess, the torque required, in particular for loosening the possibly also calcified screw connection, can hardly be applied to the known jet regulator
If small screwdriver blades are still used here, there is the risk that the blade of the screwdriver curls and when excessive torque is applied, the recess rises laterally upwards and the surrounding grid or grid structure widens or become damaged and the jet regulator will not be usable

Embodiment Construction

[0034] exist Figure 1 to Figure 3 shows a sanitary plug-in unit 1 , which can be installed in the outlet of a sanitary outlet fitting (not shown further here) and can be axially sealed relative thereto by means of an annular seal 26 . The plug-in unit 1 has an inflow-side filter or pre-sieve 2 , which filters out dirt particles entrained in the incoming water that could otherwise adversely affect the plug-in unit 1 . function of the unit. The plug-in unit 1 also has an outflow-side jet regulator 3 , which shapes the water flowing through into a uniform, non-splashing, and optionally also bead-shaped, soft water jet. Between the inflow-side pre-sieve 2 and the outflow-side jet regulator 3 a flow restrictor can be provided, which reduces the through-flow cross section. Instead, however, a flow regulator 4 is provided here, which regulates the water flow to the jet regulator 3 to a fixed flow volume per time unit, independently of the pressure.

Abstract

The invention relates to a spray regulator (3) having a spray regulator housing (4), which housing has on the outer housing circumference thereof an external thread (5) by which the spray regulator (3) can be installed in an internal thread provided in the water outlet of a sanitary outlet fitting, wherein a downstream housing end face (6) of the spray regulator housing (4) is designed as a grid or mesh structure having through flow holes (7) for the water flowing through the spray regulator (3), said grid or mesh structure having at least one first slit-like recess (8, 9) which serves as a tool engagement surface. A second slit-like recess (9) intended as a tool engagement surface is provided in the slot base of this first recess (8), wherein the second recess (9) has a smaller recess cross-section by comparison with the first recess (8).

Description

technical field [0001] The invention relates to a jet regulator, which has a jet regulator housing, the jet regulator housing has an external thread on the outer circumference of the housing, and the jet regulator can be mounted on a device by means of the external thread In the internal thread in the water outlet of the sanitary water outlet fitting, wherein, the housing end face of the outlet side of the jet regulator housing is formed as a grid or grid structure, and the grid or grid structure has a function for making the water Through-flow openings of a flow jet regulator, the grid or grid structure has at least one tool interface, which is formed as a slot-like recess of the grid or grid structure and is intended for rotation tool. Background technique [0002] A jet regulator is already known from EP 2 597 214 A1, which has a sleeve-shaped jet regulator housing which has an external thread on its housing outer circumference. By means of the outer thread, the jet reg...
