  • connection member 26 is with a Ring attachment 36 provided on one shoulder of the outer casing 13 as well as on the end face of the nozzle housing 10 when the connecting member 26 is in its position according to FIG. 1b.
  • O-rings 66, 68 seal the rotation space with respect to the cup bearing 22 or the connector 26 from the outside.
  • the rotor 18 comprises a cylindrical outer sleeve 30 in which an inner body 32 is arranged, in which the longitudinal axis 44 of the rotor 18th defining flow channel 56 is formed, the constriction 54 and which is followed by a nozzle 20 which supported on the cup bearing 22.
  • the throughflow channel is in the region of an inflow opening 24 of the rotor 18 56 designed as a double rectifier, the one a shorter one Rectifier section 46 forming pre-rectifier and a longer one Rectifier section 48 includes main rectifier, between one of which is shorter than the rectifier sections 46, 48, preferably a calming section 52 of approximately 2 to 4 mm in length is provided, the cross-sectional area larger than that of each rectifier section 46, 48 is.
  • the inner wall of the inner body delimiting the flow channel 56 32 provided with longitudinal ribs 50.
  • the rotor 18 is at its end facing the locking element 28 provided with a rolling element 60 with which the rotor 18 in the 1a rolls on the inner wall of the nozzle housing 10.
  • Flow channels are formed in the rolling element 60, which flow upstream initially at approximately the same angle to the longitudinal axis 44 of the Rotor 18 as the inclined surface of the locking element 28 to the longitudinal axis 16 of the nozzle housing 10 extend. Then the flow channels go into an approximately parallel to the longitudinal axis 44 of the rotor 18 extending downstream area. In this area the Rollers 60 due to the formation of the flow channels wing 58, which are distributed in the circumferential direction of the rotor 18 and approximately protrude perpendicularly from the outer sleeve 30.
  • the flow channels are preferably formed as grooves milled in the rolling element 60.
  • the outer sleeve 30 has at its end facing the cup bearing 22 of the rotor 18 two protruding holding arms 62 on the ends of the holding arms 62 engage in recesses 64 formed in the cup bearing 22 are.
  • the water flows into the flow channel via the inflow opening 24 56 into which it enters the nozzle 20 and through the outlet opening 14 emerges from the rotor nozzle in the form of a cone jet.
  • the longitudinal ribs 50 of the two rectifier sections 46, 48 and those in between arranged calming section 52 ensure that the in water flowing into the rotor 18 soothes, i.e. the rotational movement of the Water is reduced.
  • constriction 54 in the flow channel 56 of the rotor 18 provides sure that the rotor 18 through the inflowing water to the cup bearing 22 is pressed.
