  • the other orifice E6 communicating with this chamber 6 is closed, while the orifice E5 is connected to the outlet 18.

  • the liquid of the chamber 5 is discharged through the orifice E5.
  • the end 36b of the spring 36 remains in abutment against the upper transverse wall of the housing 43 and holds the slide 16 in this position.

  • the end 36a passes upwards, according to Fig.1 the horizontal plane passing through the axis 38 of articulation of the rod 37, the latter rocker relative to the pusher A so that the end 36a passes above the axis 38 when we look Fig.1 .
  • This step is schematically represented on Fig.8 , brought back to the horizontal.
  • the end 36b of the spring moves in the housing 43 to bear against the other transverse wall of the housing 43 and exert a thrust on the slide 16 to move it to the other stable position. Thanks to the geometry provided for the link 37 and the arms 45, the end 45b of these arms simultaneously bears against the abutment 46 (FIG. Fig.9 ). This synchronous attack of the slide 16 assists the force of the spring 36 to overcome the sliding resistance of the slide 16.

  • the vertical reciprocating movement of the membrane 7 and the pusher A allows the pumping and dosing of the additive through the metering subassembly 21 whose pumping piston 24 is driven by the membrane 7.
  • the drawer 16 is held in place against the mirror 17 by the spring 36.
  • the drawer is pressed against the ice 17 by the pressure difference and the liquid inlet flow when there is liquid flow.
  • the flatness and surface finish of the drawer 16 and the window 17 ensure a good seal between the two elements.
  • the slide 16 is subjected to a normal force to the ice 17 equal to the bearing surface multiplied by the pressure difference.
  • the force to move the slide 16 is a transverse force which is equal to the normal force on the slide 16 multiplied by the coefficient of friction between the slide 16 and the ice 17.
  • the movement of the membrane 7 is mechanically connected and synchronized with the triggering of the switching.
  • the movement of the distribution slide 16 on the window 17 is generated by the rotational movement of the compression spring 36 which "balances" the forces sometimes towards the first stable position, sometimes towards the second stable position, thereby causing the slide 16 to move. by sliding.
  • the metering subassembly 21 connected to the membrane 7 via the pusher A, sucks and then directly injects the additive product at the outlet of the metering device.
  • the rod 37 driven by the pusher A, provides the compression of the spring 36 and the synchronization of the slide 16. Indeed, under certain limiting conditions (pressure, flow) the spring 36 may not be sufficient to slide the slide 16 on which exerts a pressure difference (pressure at the inlet 14 of the metering unit less pressure at the outlet 18).
  • the assistance provided by the rod and the arms 45 constitutes a synchronization which makes it possible to ensure switching in these conditions: the drawer 16 is sufficiently pushed by the arms 45 towards the intermediate position, illustrated on Fig. 10 and 11 and on Fig. 4 , putting all the diaphragm chambers in communication with the outlet and dropping the pressure difference. Efforts on the drawer 16 drop and the spring 36 continues the travel of the drawer 16 to the other stable position causing switching.
  • the drawer 16 is placed by the arms 45 in the intermediate position illustrated on Fig.4 with communication of the two chambers 5,6 with the output, and therefore the input 14 with the output 18.

  • Such a dispenser makes it possible to pass water laden with particles, in particular thanks to membrane operation.
  • the flow range is very wide ranging from 2 - 3 l / h to 2000 l / h for example.
  • the operating pressure range is also wide, for example from 0.1 bar to 4 or 5 bar.
  • the dosage of additive in the main liquid can be of the order of 2% and even 5%.
  • the cubic capacity (flow rate per rise or fall cycle) can be approximately 0.4 liters.
  • the diameter of the membrane may be of the order of 110 mm and the stroke of 25 to 30 mm.
  • the orifices in the plate 17 may have a section of approximately 1.3 cm 2 .
  • the diaphragm dispenser with distribution slide switch makes it possible to separate the distribution mechanism from the piston or diaphragm drive part. As a result, the disassembly of these elements can be done independently of one another.
