- One level of regulating webs 7 is formed on each of the wall sections 17.
- the regulating webs 7 arranged in the individual web planes can also be well formed in different web cross-sections despite the comparatively small spacings.
- the plate-shaped flow straightener 5 with the inner wall 8 of the jet regulating device 4 molded onto it at right angles is inserted from the outflow side A of the jet regulator 101 into the interior of the jet regulator housing 1 until an on the outer circumference of the flow straightener 5 provided locking projection in a complementary locking groove snaps into the inner circumference of the jet regulator housing.
- This positive connection of the flow straightener 5 on the inner circumference of the housing of the jet regulator housing 1 also fixes the jet regulating device 4 formed on the flow straightener 5 in the housing interior.
- the jet regulating device 4 of the jet regulator version 115 shown in FIGS. 15 to 17 can also be fixed in the housing interior of the jet regulator housing 1 in a comparable manner. Is the
- Jet regulating device 4 connected to the flow straightener 5, these components 4, 5 can be held securely and firmly in the jet regulating device housing 1 if, in addition or instead, one with the
- the jet regulating device 4 is first pushed into the jet regulator housing 1 from the downstream side, before the plate-shaped flow straightener 5 is then inserted into the jet regulator housing 1 and snapped or snapped into place on the inner circumference of the jet regulator housing 1 is that the jet regulating device 4 is held securely and firmly in the housing interior of the jet regulator housing 1.
- the jet regulator shown here and in particular here the jet regulator version 101 only has at least one slot-shaped ventilation opening 21 on only one of its longitudinal walls 19 and here only on its longitudinal wall 19 facing away from the user in the position of use opens into the mixing zone arranged below the jet splitter 2 in the direction of flow and can flow into the interior of the jet regulator housing 1 through the ambient air.
- the aerator housing 1 has an indentation 20 on its outer circumference of the housing on the longitudinal wall 19 facing away from the user in the position of use, which leads from the outlet side A of the aerator housing to the ventilation opening 21. If the inner wall 8 is now arranged approximately in the longitudinal center plane of the jet regulator housing 1, this leads to the inner wall 8 being at a greater distance from the longitudinal wall 19 facing the user in the position of use than in relation to the wall 19 facing away from the user in the position of use and having the ventilation opening 21 Longitudinal wall 19. In order for the water flowing through to flow through evenly distributed over the cross section of the jet regulator housing 1, the jet regulator version 121 shown in FIGS 7 are aligned.
- the regulating webs 7 reaching with their free web ends up to the adjacent longitudinal wall 19 have a different web length on the two sides of the inner wall 8, the water flowing through is uniform over the Cross-section of the jet regulator housing 1 distributed because the longitudinal axes of the splitter openings 3 of the jet splitter 2 are each aligned approximately with the web center of the adjacent regulating web 7.
- the jet regulating device 4 can be designed as a two-component or multi-component injection-molded part and, in particular, made from an elastomer plastic 22.
- the flow straightener 5 is designed as a two-component injection-molded part, with a hard-elastic plastic component 23 shown in fine-dashed lines in the figures forming a frame stiffening the flow straightener, while the water-wetted grid structure and / or the outer circumference of the flow straightener 5 resting on the inner circumference of the housing is made at least superficially from an elastomeric plastic 22 which is cross-hatched and has a significantly lighter effect.
- An embodiment is preferred in which at least a partial area of the rectifier webs 13 is made from an elastomer plastic 22 or has at least one surface made from an elastomer plastic 22.
- FIGS. 24 and 25 show a modified further embodiment 124 of a rectangular jet regulator in a longitudinal section (cf. FIG. 24) and in a perspective top view of its flow straightener 5 (cf. FIG. 25) forming the outlet end face of this jet regulator 124.
- the flow straightener 5 of this jet regulator 124 has a lattice structure made up of a group of parallel first straightener webs 13 which are spaced apart from one another and which are aligned with at least one second rectifier web 13 'and here with two spaced apart second rectifier webs 13' at intersections.
- the first rectifier webs 13 each have free web ends 24 on both sides, which web ends 24 are each shaped here as latching cams.
- the flow straightener 5 of the jet regulator 124 can preferably be releasably latched with the free web ends 24 in a locking groove 25 arranged on the inner circumference of the jet regulator housing 1 and also of the jet regulator 124.
- the first and the second rectifier webs 13, 13 ′ delimit the outlet openings 6 of the downstream flow straightener 5 between them and, if appropriate, also the inner circumferential wall of the housing of the jet regulator housing 1.
- the distance between the forks 28, 29 delimiting the fork opening 27 of the at least one holding fork 26 is adapted to the wall thickness of the inner wall 8 associated with the at least one holding fork 26 and is dimensioned so that the inner wall 8 is preferably at right angles to the lattice plane defined by the lattice structure of the flow straightener is held in particular on this flow straightener 5 so that it does not tip over. While the lattice structure of the flow straightener of the jet regulators 101, 106, 110,
- a circumferential retaining ring is the retaining ring with which the flow straightener can be locked into a locking groove on the inside circumference of the jet regulator housing 1, such a retaining ring is dispensed with in the flow straightener 5 of the jet regulator 124 shown in FIGS
- Housing cross-section of the jet regulator housing 1 for guiding the water flowing through is available without further constrictions.
