Definitions

  • the present invention relates to a dual-flow flush comprising at least two control buttons for respectively controlling the delivery of a first large volume or a second smaller volume.
  • the existing systems are not very reliable in operation, and in particular it often happens that the small volume delivered "drifts" over time and becomes too low, so that this functionality becomes inoperative.
  • Double-flow flushes of the prior art are already known, in particular in US 2011/0155934 .
  • these flushes have hydraulic actuation and are expensive and complicated to manufacture and are unreliable.
  • the at least two-stream flushing device is as defined in claim 1, improvements being defined in the sub-claims.
  • the actuation means comprise an actuation timer valve which opens or closes, during a time interval which may take at least two values, a duct for emptying the timing chamber of the control timing valve.
  • the actuating means comprise a rod, a pallet is interposed between the two control buttons and the rod and is rotatably mounted with respect to a pivot point, the rotation of the pallet causing the displacement of the following rod an actuation stroke, and adjustment means adjust the rotational stroke of the pallet under the effect of the low volume button, so as to adjust the actuation stroke of the rod when the control is carried out by the low volume button, to thus adjust the second delivered volume.
  • the adjustment means comprise a wedge mounted to slide relative to the pallet and comprising a bottom end section, an intermediate inclined section and a top end section, the wedge thus acting on the position of a stud resulting from the small volume button, the stud being able, depending on the respective sliding of the wedge with respect to the pallet, to press either on the low section, preferably horizontal, of the wedge, either on the inclined or sloping section of the wedge or on the high end section, so that the stud is more or less close to the small button volume, which adjusts the stroke of the actuating rod.
  • a dual-flow flushing device Preferably, the hunt is embedded in a facade.
  • a large volume button 4 protrudes out of the faceplate and allows the user to select the sending of the large volume of six liters into the flush.
  • a button 5 of small volume also protrudes out of the faceplate and allows the user to select the sending of a small volume in the flush, corresponding to a fraction of the large volume, for example three liters.
  • Springs 6 and 7 are mounted in conjunction with the buttons to return the latter to the initial position after being pushed by the user.
  • the volumes (small or large) of flushing water are delivered by a flush opening connected to a water supply pipe.
  • the flushing opening is closed by a valve 20.
  • the more or less closing of the opening by the valve is controlled by a delay valve 21, called control.
  • the control timing valve 21 comprises a control timing chamber 22, the volume of which varies as a function of the displacement of an upper plate 23 which delimits the timing chamber on the top.
  • a spring is arranged so as to push the upper plate 23 upwards.
  • the plate 23 is connected to the valve 20 to cooperate with the latter, so that in the high position of the plate (maintained by the equality of the water pressures on both sides. other and by the action of the spring) the valve closes the flushing opening, while in the lowered position of the plate, the valve does not block the flushing opening and lets a flow of water flow .
  • the timing valve 21 is placed inside the water supply duct 24 between a water inlet opening 25 and the flushing opening 26 closed by the valve.
  • the plate 23 delimits the delay chamber 22, but not however completely sealed.
  • the water from the duct can pass into the chamber 22 at the peripheral edge of the plate 23.
  • the opening 26 is closed by the valve 20 and the timing chamber is filled with water, the duct being under the water pressure from the supply network and the water pressure being the same above and below the plate, which is therefore in the high position.
  • the movement of the plate 23 is controlled by completely or partially emptying the timing chamber 22 of the valve 21 via a drain pipe 28.
  • the delay chamber 22 is emptied through the conduit 28 of a given quantity, namely a large quantity in the case where it is desired that the valve 20 remains out of its seat for a long time, for a large flushing volume. delivered, and a smaller amount in the event that it is desired that the valve 20 remains out of its seat for a shorter duration for a smaller volume of hunting delivered.
  • This given amount is determined by the time the duct is open. If a large quantity of water is emptied, it is ensured that the time taken by the plate 23 to rise under the effect of the water which infiltrates into the delay chamber at the level of the periphery of the plate is large and therefore that the time during which the valve 20 is open is large, and therefore that the flush delivers a large volume of flush.
  • the time taken for the plate 23 to rise under the effect of the water which infiltrates the delay chamber at the periphery of the plate is made to be less, and therefore that the time during which the valve 20 is open is less, and therefore that the flush delivers a smaller flush volume.
  • This total or partial emptying of the delay chamber 22 causes the descent of the plate 23 (since the pressure of the water above becomes greater than the pressure inside the chamber and the spring being adjusted so as not to s 'oppose the descent of the plate in such a case) which then drives the valve 20 out of its seat and opens the flushing opening 26, allowing the delivery of a volume of water.
  • the water is delivered while the timing chamber 22 fills up again, gradually raising the plate 23, which gradually returns the valve 20 in its seat, to the position in which the water pressures on both sides of the plate 23 equalize and the valve closes the opening 26.
  • the time taken by the delay chamber 22 to fill up after it has been emptied defines the flow rate of the flushing water.
  • the filling time is long and the flushing volume delivered is large and in the case where the The plate is lowered from a lower height (adjustable according to the volume of water drained), the filling time is less and the flushing volume delivered is correspondingly lower.
  • the flushing control device further comprises a timing initiator valve 27 (which therefore also comprises a timing chamber of actuation).
  • the valve 27 is arranged so as to open a duct 28 for emptying the control delay chamber 22 and to close it.
  • the initiator valve 27, or actuator comprises a rod 8 whose movement causes the opening of the drain pipe 29 of the timing chamber of the initiator valve.
  • This emptying of the timing chamber of the priming valve causes, according to a principle identical to that described for the cooperation between the plate 23 and the valve 20, the opening of a valve of the duct 28 while the timing chamber of the valve 27 fills up again.
  • the volume drained from the timing chamber is proportional to the stroke of the rod 8, itself dependent on the button pressed between the low volume button and the high volume button.
  • the pallet is rotatably mounted relative to an end pivot point 10.
  • the pallet comprises a stud 11 intended to come into contact with the rod of the button 4 of large volume and a stud 12 intended to come into contact with the rod of the button 5 of small volume.
  • the stud 11 is closer to the pivot point than the stud 12.
  • a conduit 29 in the initiator valve 27 places the timing chamber of the valve 27 in communication with the outside as well as with the conduit 28 for the fluids to discharge the water taken from the chamber 22 at the level of the opening 26, simultaneously with the delivery of the large or small flush volume through the opening 26.
  • the rod of the button 4 comes to press on the stud 11, causing the pallet to rotate relative to its pivot point 10 and the pallet presses the rod 8 for actuating the priming valve.
  • the corresponding stroke of the rod 8 causes the emptying of the timing chamber of the priming valve, causing the opening of the conduit 28, then the emptying of the timing chamber 22 and finally the delivery of the large flushing volume while the chamber 22 fills again, after the closure of the conduit 28 following the refilling of the timing chamber of the initiator valve.
  • This adjustment wedge 13 comprises a slope stop which acts on the position of the stud 12, as a function of its position.
  • the stud 12 presses on the lower horizontal part of the wedge.
  • the middle position, shown in figure 5 the stud 12 comes into contact with the inclined or sloping part of the wedge.
  • the stud 12 comes into contact with the wedge in the upper adjustment part.
  • the latter is more or less close to the button 5 of small volume.
  • the farther away the stud is from the button 5 the less will be the stroke achieved by the rotation of the pallet during the action by the button 5 and the less will be the translation of the actuating rod of the initiator.
  • the stroke of the actuator rod is proportional to the volume emptied of the timing chamber of the priming valve 17 and therefore to the time during which the duct 18 empties the timing chamber 22 and therefore to the time during which the valve 20 is out of his seat and leaves the opening 26 open.
  • the time during which the opening 26 is open also determines the volume of hunt issued.
  • the volume of the small flush can be adjusted with precision, simply by sliding the wedge relative to the pallet.
