- FIG. 23 b shows how this shape increasingly cuts into the internal thread 3 as the external thread 2 is screwed in further starts.
- FIG. 23 c the jet regulator is completely mounted and the shaping designed as a sealing wedge 27 is completely engaged with the internal thread 3.
- the superimposed shading in FIG. 23c indicates that the material of the shaping provided in the external thread 2 and / or of the internal thread 3 is displaced.
- the jet regulator housing 1 material same on its housing outer periphery and at least one, with the external thread 2 carrying GeHouseab ⁇ section of the jet controller housing 1 and it integrally formed cross-section enlargement 6; 7, which can be applied sealingly on the front side and / or on the inside circumference of the water outlet 4.
- These Querterrorismserweite ⁇ ments 6; 7 are formed at the jet regulators 127 and 130 in a flange and extend in the housing circumferential direction of the jet regulator housing 1 via at least one of Drainage holes 22.
- the flange Quer4.000serwei ⁇ Chippings 6; 7 on the outer circumference of the housing of the jet regulator housing 1 of the jet regulators 127, 130 are provided between the external thread 2 and the at least one drainage opening 22.
- the jet regulator 127 shown in FIGS. 27 to 29 the flange-like cross-sectional extensions 6 are each arranged on the inflow side immediately above one of the drainage openings 22, the jet regulator 130 shown in FIGS. 30 to 32 has a flange-like cross-sectional widening 7 which acts as one around the Jet regulator housing 1 circumferential annular flange is formed.
- the flange cross-sectional extensions 6; 7 at the beam regulators 127, 130 are here as ⁇ screwed stop forms, which limits the screwing of the external thread 2 in the internal thread 3 in the water outlet 4 of the outlet fitting.
- the cross-sectional widenings can be applied sealingly on the outlet face or, as here, on the inner circumference of the water outlet.
- the jet regulators shown here are characterized by a high seal in the area between the housing outer circumference of the jet regulator housing 1 and the inner circumference in the water outlet 4 of the outlet fitting ring zone 5 on, without the need for sealing separate and particularly different material sealing rings.
- the jet regulators 101, 104, 111, 115, 127 and 130 shown here are therefore designed without sealing rings and come without a sealing ring made of elastic material separate from the jet regulator housing 1.
