• French patent n ° 2.665.201 and European patent n ° 0.553.577 A1 issued to the inventor describe a device in the form of a control button fixed on the tank cover, actuating a device made up of two rings in which propeller-shaped openings have been made; the outer ring rotating on the fixed inner ring drives two transverse studs integral with an inner piston controlling or interrupting the emptying, the return of the button to position 0 being effected by the action of two return springs.
• This invention was a significant development in the mechanisms actuated by pull, chain or push button and allowed the programmed release of the only quantity of water required.
• the economizer device described included a first ring and a second ring, the relative rotation with respect to the other actuated by a control button with several positions caused the piston to rise or fall acting on the drain as well as return means to ensure the return of the control to a position of rest.
• the rings had openings, the first helical prop, the second defining a contour of predetermined shape controlling the dynamics of the piston in relation to the previous opening and vice versa.
• the object of the present invention is the same as that of the aforementioned patents, but the improvements made to the previous system, the mechanisms of which will be described in detail later, are of five orders: - the choice of the programmed volume of emptying is determined according to that the knob is turned clockwise or counterclockwise and no longer only in one direction; the zones for raising and lowering the piston are simplified by improved cutouts of the rings ensuring the device a predetermined dynamic and no longer adjustable;
• the piston encloses:. either when the device is inside, a gripper for gripping the cable or the rod shown in FIG. 5a,

• FIG. 2 are diagrammed on the outer ring (8) the two possible paths of the stud (13) of the piston (12) depending on whether one prints on the cover (9) a quarter turn to the right or to the left.
• the knob is turned 90 ° anticlockwise, the nipple passes successively from position 0 to position 1 then 2 where it is maintained by the principle of Archimedes under the effect of the pressure of the water exerted on the valve then is recalled by the tension of the spring (10) not shown in this figure in position 3 and finally in position 0, this recall interrupting the flush.
• the springs (10) and (11) are housed in a circular groove and secured to a movable stop and to a fixed stop.
• a conical spring (20) centered on the piston head exerts via the piston a push on the stud (13) of which it slows the return allowing a greater emptying and then helps to interrupt the emptying by allowing a quick closing of the valve.
• a second embodiment is embodied by a control device inside the flush tank.
• the new device of the piston head appearing in FIG. 5a has the following characteristics: the cylindrical body of the piston (12) is designed so as to be able to optionally place therein a hollow threaded head (12 ') in plastic in which, when the device is mounted, a hollow threaded ring (14) is introduced which comes to bear on a claw (14 ') which holds the rod (15) when this ring (14) is screwed to block the claw ( 14 ') enclosing the cable or the valve control rod.
