  • the invention also aims, according to at least one embodiment, to provide such a siphonic flush mechanism that allows to solve a permanent leakage problem in case of low flow of the water network caused by a support maintained on the control button or with a deliberately low force and a slow speed of support on the control button or during a return to service after a change of equipment (batteries, tap ).
  • Another object of the invention is, according to at least one embodiment, to provide such a flushing mechanism that does not require a control effort too high for the user.
  • the invention there is a reliable hunting mechanism, requiring no high control effort.
  • thanks to the lifting means of a water column it is possible to renew the air of the volume of air trapped essentially between a wall of the movable element and the outer wall of the fixed element.
  • the lifting means of a water column allow, when actuated via the control member, to evacuate a column of water present in the siphon, so as to recreate a volume of air necessary for the formation of an air seal for the siphon.
  • water column is meant a body of water stored vertically.
  • the water column may be annular, for example.
  • the movable element and the bell integral with it may occupy a high position, at rest, or a low position, after actuation of the control member by a user.
  • the passage in the lower position through the actuation of the control member allows to put under water the mechanism, so that it initiates siphoning and thus the evacuation of water from the reservoir to the toilet bowl.
  • the movable element and the bell advantageously remain in the low position during the entire evacuation of the water.
  • the height of the fixed element is less than the height of the water contained in the reservoir when the reservoir is full, that is to say at its maximum level, makes it possible in particular to limit the downward movement of the movable member to move from the high position to the low position, to put under the water the bell as quickly as possible, when actuating the control member.
  • the means for lifting a water column comprise, in a particular embodiment, a scraper forming a substantially horizontal annular plate integral with a wall of the movable element, the scraper providing at least one annular clearance with the wall outer part of the fixed element to allow the flow of water.

  • the presence of means of recall can in particular accelerate the raising of the lifting means of a water column, so as to effectively remove water from the column concerned.
  • the bell may include an opening configured to, after evacuation of a predetermined amount of water out of the tank, allow air to be introduced under the bell so as to interrupt the evacuation of water, so as to carry out a small hunt of water.
  • the mechanism may, in this case, comprise a shutter of the opening, configured to occupy two positions: a closed position to close the opening so as to allow the total or almost total evacuation of the water from the opening. tank to achieve a large flush and an open position to not close the opening to achieve a small flush.

  • the mechanism comprises at least two, for example exactly two ducts, one for large hunting and the other for small hunting.
  • the mechanism may further include a wall portion extending proximate the opening, within the bell, configured to limit disturbance of the water discharge associated with the air supply caused by an air leak.
  • this wall makes it possible for example to interrupt the flow of water discharged only when there is massive inflow of air and not a slight leakage of air through the opening, especially if it is not completely closed.
  • the fixed element can be made in one piece with the reservoir. This is particularly the case for example for a tank of polymer material. In a variant, particularly in the case of a tank made of ceramic material, the fixed element can be made independently of the tank and be attached thereto.

  • This baffle which takes up space when the movable element is in the lower position during the evacuation of the water out of the tank, can allow, during the ascent of the movable element to a high position, to release the occupied space, which allows to renew the air present in the space. Indeed, the fact of releasing space allows the air to be inserted.

  7. Einheit nach einem der Ansprüche 4 bis 6, wobei der Mechanismus einen sich nahe der Öffnung (50) im Inneren der Glocke (15) erstreckenden Wandabschnitt (60) umfasst, der dafür eingerichtet ist, die Beeinträchtigung des Ablassens von Wasser, die mit dem durch ein Luftleck hervorgerufenen Eindringen von Luft zusammenhängt, einzuschränken.
  8. Einheit nach einem der vorhergehenden Ansprüche, bei der das feste Element (3) einstückig mit dem Tank (2) ausgeführt ist.
  9. Einheit nach einem der vorhergehenden Ansprüche, bei der das bewegliche Element (3) eine dreifache Wand umfasst, nämlich:

    - eine Zwischenwand (22), die sich zwischen der Außenwand (6) des festen Elements (3) und dem Spülrohr (5) des festen Elements (3) erstreckt,
    - eine Innenwand (23), die sich im Inneren des Spülrohrs (5) erstreckt,
    wobei wenigstens ein Teil des Raums, der einerseits zwischen der Außenwand (21) des beweglichen Elements (10) und der Außenwand (6) des festen Elements (3), und andererseits zwischen der Zwischenwand (22) des beweglichen Elements (10) und der Außenwand (6) des festen Elements (3) gebildet wird, dafür eingerichtet ist, beim Befüllen des Tanks (2), und wenn der Tank (2) voll mit Wasser ist, eine Luftdichtung (17) zu bilden.
  10. Einheit nach einem der vorhergehenden Ansprüche, bei der das bewegliche Element (10) zwei fest und dicht miteinander verbundene separate Bauteile (30, 31) umfasst, die aus einem inneren Teil (30) des beweglichen Elements und einem äußeren Teil (31) des beweglichen Elements bestehen.
