Description

From 25 2551111 In the first phase of operation of the device of

  main patent, the closure of the valve and, at the end of this closure, the supply of the small tank, is carried out by means of the device of known type described on page 2, lines from 3 I to 40 and page 3, lines from I to 9. One could advantageously replace this device by that which is the subject of FIG. I in which the rod (I)

  of the valve comprises an internal recess (2) The piston of the jack, in addition to the peripheral sealing gasket (3), comprises an IO housed gasket (4).

  The rear flange (5) of the jack has an orifice (6) which is that of the water inlet controlling the closing of the valve This flange (5) further comprises, in its center, a cylindrical tube (7) which penetrates inside the body of the cylinder I 5 in the axis of sliding thereof and extends outside, by the conduit (8) which supplies the reservoir The external diameter of the tube (7) is arranged so as to slide in the recess (2), the seal (4) ensuring the seal:

tee along the slide.

  The length of the tubing (7) inside the jack's coips is established so that this queen end position is

  stroke, corresponding to the closing of the valve, the piston escapes from the tubing by leaving a space (9) between the internal face of the piston and the end of the tubing The orifice (IO) and the duct (II) are shown l 'exhaust.

  The operation of the device is as follows: When an operational valve is opened and the water, arriving at (6), pushes the piston which passes from the position shown in dotted line to that shown in solid lines because the 30 seals (3) and (4) prevent any communication between the compartments placed on either side of this piston and this for to Bte the duration of this sliding The exhaust is ef

  made through the orifice (IO) and the conduit (II).

  We see that the valve having reached its position of iron 35 meture, the water continuing to arrive in (6) is introduced through the space (9) in the tubing (7) and, through the conduit (S), will supply the tank During the reopening phase of the valve, the water enters the body of the cylinder through the orifice (IO) and the exhaust takes place through the orifice (6) which, at this moment is in 40 communication with a drain, A second new provision compared to the main patent relates to the air evacuation system inside the siphon in the filling phase of the latter at the time when the level rises at the same time, in the bowl and the siphon. The device described in the main patent consists of a simple conduit, starting from the culminating part of the siphon, to lead into the last descent Ctte being in the air

  free, air can enter the siphon and obstruct the I Siphonic suction.

  To remedy this drawback, the following device can be used which is the subject of Figure = I, in which an orifice (I 2), placed at the highest point of the siphon, communicates with a pipe (I 3) in ascending slope This conduit (I 3) I 5 opens, through the orifice (I 4), into the lower flange of a third bowl (I 5) which has an upper cover (I 6) in which a bore (I 7) is formed. ) comprising a seal (I 8) The housing (I 5) provides, in its internal part, a compartment (I 9) inside which moves a rod (20) which necks smooth in the bore (I 7) and carries, at its lower part, a valve (2 I) provided with a seal, for example made of rubber. The axis of the rod (20), placed in a substantially vertical position, corresponds to the axis of the orifice (I 4) so that the bending of the rod (20) causes, alternately, by through the valve 2 I, the opening and closing of the

orifice (I 4).

  In the upper part of the compartment (I 9) is an orifice (22) extending outwardly through the conduit (23), which opens into the outlet sheath The conduit (23) is

downhill.

  The rod (20) extends outside the bore (I 7)

  by a rod (24) itself integral with the rod (25) of the control distributor, the assembly being arranged so that the rods (20) and (25) are parallel and their sliding perfectly synchronized.

  The device works as follows: In the non-use position, the control slide is lowered and the valve (2 I) closes the orifice (I 4) To switch on an ope. 40 ration, the distributor control rod (25) is raised and,

  in doing so, the valve (21) is also raised which occupies the position (2 I a) shown in dotted lines.

  The liquid is introduced into the siphon and the air pocket which forms in its culminating part is evacuated by the orifice 5 (I 2), the conduit (I 3), the orifice (I 4), the compartment (I 9) sufficiently dimensioned for this purpose, the orifice (22) and the conduit

(23) towards the downpipe.

  When the siphon is filled, the duct (I 3) in turn fills with liquid and the level rises inside the comI O partiment (I 9) Stopping the injection of liquid into the bowl

  intervening at a level lower than that of the orifice (22), there can not occur the slightest flow likely to impede operation.

  The blocking of the balls, at the same time as it stops the injection of liquid, causes the lowering of the control rod (25) and, simultaneously of the rod (20) and the valve (21) which then closes the orifice (I 4) so that there can be no reintroduction of air during the siphonic suction The liquid which could have been introduced inside the Qom 20 partimeet (19) before closing the valve (2 I) is evacuated in the siphon by the conduit (I 3) now in the slope position

  from the start of the next operation.

  The seal (7) prevents odors from rising.

  In the main patent, a known type of ball box system is described and used which organizes the injection of water into the bowl and the stopping of this injection by blocking the balls which takes place at a level corresponding substantially to that of injection Or it may happen that, to improve the operation of the device reduce the consumption of water while ensuring maximum watering of the cux

  vette, there is interest in causing the blockage at a level substantially lower than that of the injection.

  Figure III shows a device responding to this possible arrangement.

  A ball boot (26) contains, like those of the cone type, a lower ball of high density (27) and a ball

  higher density lower than one (28).

  Between the two is placed any volume such as for example a sphere (29) of very low density The interior of the box is arranged to allow free circulation.

  tion of water The sphere (29) is, in its upper part,

  in contact with the lower part of the ball (2%).

  The level (30) corresponds to that of the natural flotation of the sphere (29) We understand that, when this level 5 rises for example to (30 a), the sphere (29) lifts and in turn lifts the ball (28) which, when placed in

  the trajectory of the jet, causes blocking.

  In many countries there are regulations relating to the layout and installation of sanitary appliances in order to ensure the non-pollution of the water supply network.

  Figure IV shows a device for pocketing a

  such pollution, this in the context of the present invention.

  It shows the assembly: actuator-valve, distributor of I 5 control in position of non-use or opening in lines

  full, the di-ve-rmure position being shown in dotted lines.

  The water in the supply circuit enters the distributor through the orifice (3 I) and leaves it through the orifice (32) which is extended outside by the conduit (33) which opens out through the orifice. (34) inside the cylinder in the compartment (35) The position of the pistons of the household dispenser, the interior thereof, a compartment (36) through which the orifices (3 I) and (32) communicate valve (37), integral with the rod (38), carries a peripheral seal (39) and extends along the cylinder side, by a cylindrical sheath (40) of the same diameter as it, the assembly being intended to slide at the interior of the descent tee (4 I) A seal housed (42) in the cylinder side tee-ensures, in connection with the seal (39), 1st guide

  and the sealing of the valve during all the sliding.

  It can be seen that, in the closed position of the valve and also during the entire opening phase, the effluents located in front of the valve in the terminal part (43) of the siphon can never come into contact with the rod (38) which does not will therefore never be polluted. As a result, the water in the compartment (35), the conduit (33) and the compartment (36) will remain free of any pollution and will therefore never be able to pollute the supply network even in the case

  would produce suction through the orifice (3 I).

  To also prevent any pollution from being able to rise from the bowl to the distributor through the

  duit for emptying the water from the tank, we can as shown in Figure i V, create a discontinuity (44) between the part (45) of the duct which extends the bottom of the distributor and the part (46) which is connected at the bottom of the bowl.

5 Finally, to avoid any pollution coming from the ball box, the supply duct connecting the latter to the reservoir to be seen will be arranged so as to drain completely after each operation, either in the ball box or in the tank. I O I 5
