  • the jet disk is provided with passage channels which are circular in cross-section and which are successively released or blocked by the closure element upon rotation of the fluid-driven rotor, wherein the closure element blocks or releases approximately half of the through-channels.
  • the closure element is formed in corresponding embodiments as a slotted disc with arcuate passage slots, which at different radii and in the circumferential direction offset from each other are arranged to each release or shut off a corresponding part of lying on the respective radius beam outlet openings in the jet disk.
  • A1 disclosed shower head has at least two separate water-carrying chambers in a housing, which are each connected to a group of jet outlet openings of a jet disk.
  • a valve device is provided, which is cyclically actuated by means of a drive and designed to open and close the chambers.

  • the blocking mechanism allows the third shower head to block the control disk 2 against further rotation and thus retaining the same optionally in the position of Fig. 17 with the spray pattern S3 or in the position of Fig. 18 with the spray pattern S4 on user's request.
  • the blocking mechanism is manually operated as a combined pressure / rotation mechanism, as is known, for example, from ballpoint pens.

  • a first turbine blade 3a has a lower blocking lug 25 which coincides with the in the 11 to 18 further down, ie closer to the head portion 16 lying blocking stop 23 cooperate.
  • This blocking lug 25 ends axially after above in front of the above, that is closer to the foot part 21 lying blocking stop 24 so that it does not cooperate with this in the sense of blocking the control disk rotation.
  • a second turbine blade 3b has an upper limiting lug 26 which cooperates with the upper limit stop 24 of the actuating pin 15 and ends axially in front of the lower limit stop 23.

  • the actuating pin 15 is arranged with a predetermined transverse offset Q to the longitudinal center of the shower head in the central region of the shower head, ie its longitudinal axis 27 is offset relative to the shower head longitudinal axis 11 by the corresponding dimension Q in parallel.
  • This offset is matched to the radial extension of the blocking stops 23, 24 and the corresponding blocking lugs 25, 26 so that the respective blocking stop 23, 24 with the corresponding locking lug 25, 26 only ever cooperates in the blocking sense when the actuating stop 23, 24th is located on the side remote from the shower head longitudinal center axis 11 diametrically opposite side of the actuating pin 15.

  • the upper blocking stop 24 is in its side facing away from the shower head longitudinal axis 11 blocking position. This has the consequence that it blocks the rotation of the control disk 2, as soon as the relevant turbine blade 3b with the upper locking lug 26 against this upper blocking stop 24 comes to rest, as in Fig. 17 illustrated.
  • the control disk 2 then remains in this position, so that the fluid now exits the shower head with the fixed spray pattern S3, without changing in time.
  • the actuating pin 15 When the user then actuates the blocking mechanism again via the push button 18, the actuating pin 15 reaches its in Fig. 18 shown, again rotated by approximately 90 ° in the counterclockwise direction, in which the lower blocking stop 23 occupies its remote from the shower head longitudinal center axis 11 blocking position. In this blocking position, the lower blocking stop 23 cooperates in the blocking sense with the lower blocking nose 25 of the relevant turbine blade 3a. At the same time passes through the further rotation of the actuating pin 15 from its previous blocking position in its release position, the upper blocking stop 24, thereby being blocking interaction with the upper locking lug 26 is released. The control disk 2 thus turns from its blocking position of Fig.
