  • the jet regulator 2 ' also has two housing parts 5' which can be rotated relative to one another, 6 '. While the inflow-side first housing part 5 'is held firmly at the water outlet with the aid of the section 32', the outflow-side second housing part 6 'is rotatably connected to the section 33' of the outlet mouthpiece 28 'serving as a handle such that the second housing part 6' relative to the first housing part 5 'can be rotated.
  • steel channels 9' are provided which are preferably evenly spaced apart from one another in the circumferential direction and which capture the individual jets coming from the splitting openings 8 'of the jet splitter 7'.
  • the second housing part 6 ' is formed here from two separate parts, of which the inner sleeve 19' is inserted into an outer sleeve 42 '.
  • the jet regulator 2 ' In the annular space located between the jet channels 9 'and the spray nozzles 35', the jet regulator 2 'has at least one ring insert 36' which has a lattice or network structure and which is intended to serve as a flow straightener which compares the water flowing through.
  • this lattice structure is formed by radial webs which delimit flow holes between them. Since at least the inner portion of the circumferential walls surrounding the spray nozzles 35 'is directed obliquely outwards, the individual jets visibly emerging separately from the spray nozzles 35' are deflected obliquely outwards, so that an annular circumferential discharge jet image formed from individual jets flowing outward is produced.
  • the individual jets emerging from the splitter openings 8 ' are each guided over a deflection bevel 37' which, in this second rotational position, directs the individual jets formed in the splitter openings 8 'radially towards the central outlet opening 10' redirect inwards.
  • One of the deflection slopes 37 ' is provided between adjacent beam channels 9'.
  • a fin or fin-shaped flow divider 44 ' is provided in each of the deflection bevels 37', which already causes a first division of the inflowing water.
  • the fin-shaped flow dividers 44 ' divide the water diverted radially inwards at the deflection slopes 37' into at least two partial streams, the partial streams diverted radially inwards in this way in each case striking the pins 38 'projecting on the outflow side of the jet splitter 7' and there are divided again in such a way that the water flowing through the jet regulator 1 ′ is mixed particularly well with the ambient air.
  • the water mixed with ambient air in this way can then emerge from the jet regulator 2 'as a aerated water jet via the central outlet opening 10'.
  • Insert unit 1 shown shown the water guided over the deflection slopes 37 'in the interior of the jet regulator housing is mixed with ambient air. Since the splitter openings 8 'of the jet splitter 7' also represent cross-sectional constrictions, the individual jets formed in the splitter openings 8 'experience an increase in speed which, according to the Bernoulli equation, leads to a negative pressure on the downstream side of the jet splitter 7'.
  • the negative pressure formed on the outflow side of the jet splitter 7 'leads to ambient air entering the interior of the jet regulator housing via the spray nozzles 35' is sucked in, which are shaped there with the individual jets to form a homogeneous, non-splashing and sparkling-soft overall jet, which flows out through the central outlet opening 10 '.
  • the good mixing of the ambient air sucked into the housing interior with the water flowing through the jet regulator 2 is additionally promoted by the pins 38 'protruding in the flow direction on the outflow side of the pot bottom of the pot-shaped jet splitter 7'.
  • Exemplary embodiments 1, 1 'shown are provided on the outflow side of the deflection slopes 37, 37' spaced apart pin or web-shaped flow obstacles.
  • the jet regulator 1 shown is molded on the outflow side of the cup-shaped jet splitter 7 'on the pot bottom, pins 38', which form such pin-shaped flow obstacles.
  • the water deflected inwards in this rotational position is guided through these spaced-apart pins 38 ′ and thereby additionally decelerated.
  • a central pot base portion 40 ' protrudes from the pot base of the pot-shaped jet splitter 7', this pot base of the jet splitter 7 'being designed stepwise at least on its outflow side.
  • the pin ends of the pins 38 ' are arranged approximately in one plane.
  • the first housing part of the jet regulator is inserted into the upstream end opening of the first section 32 'of the outlet mouthpiece 28' until its circumferential annular flange 29 'projecting on the outer circumference rests on a ring shoulder 30' in the sleeve interior of the first section 32 '.
  • the first housing part 5 ' encompassed by a sealing ring 41 'which seals an annular gap which may remain between the outer circumference of the first housing part 5' and the downstream second section 6 '.
  • the outer sleeve of the second housing part 6 ' is locked in the downstream section 33', the outer sleeve 42 'also holding the inner sleeve 19' between it and the first section 32 '.
