Abstract

When the liquid is flowing a piston and magnet (1,2) are displaced to close a contactor (3). An integrated circuit (CI), capacitor (C1) and resistors (R2,R3) define a time delay before starting a motor (MR1, 4) which closes a valve (7). At the closed position a disk (5) with cut-outs operates a cut-off switch (6) to stop the motor and the piston resets. The system may be restarted by pressing a push button (BP1)

Description

La presente invention concerne un dispositif ayant la particularite deThe present invention relates to a device having the particularity of

couper la circulation en eau ou de tout autre liquide, apres une duree choisie par l'utilisateur, afin de limiter en cas de  cut off circulation in water or any other liquid, after a time chosen by the user, in order to limit in the event of

Les ruptures ou fuites plus ou moins importantes avaient des consequences materielles et fnancieres, plus ou moins lourdes selon la duree de ['incident.  The more or less significant ruptures or leaks had material and fnancial consequences, more or less heavy depending on the duration of the incident.

Le dispositif selon ['invention permet de remedier a cet inconvenient.  The device according to the invention makes it possible to remedy this drawback.

Le systeme comporte deux parties: l'une mecanique (figure 1) l'autre electronique (fgure 2) - La partie mecanique est constituee d'un piston (1) muni d'un aimant (2) qui se deplace selon la pression de l'eau, actionne le contacteur sous verre (3) qui alimente le temporisateur (Pig2) mettant en marche le moteur-reducteur (4) qui entraine sur son axe, un disque (5) muni de 4 encoches et sur lequel s'appuie le bras a roulettes du contacteur (6), ainsi  The system has two parts: one mechanical (figure 1) the other electronic (figure 2) - The mechanical part consists of a piston (1) provided with a magnet (2) which moves according to the pressure of the water, activates the contactor under glass (3) which supplies the timer (Pig2) starting the motor-reducer (4) which drives on its axis, a disc (5) provided with 4 notches and on which rests the contactor roller arm (6), as well

Des que la roulette est dans l'encoche le contacteur coupe l'alimentation du moteur-reducteur, la vanne est alors en position fermee. La pression exercee par l'eau sur le piston est alors  As soon as the wheel is in the notch, the contactor cuts the power supply to the gear motor, the valve is then in the closed position. The pressure exerted by the water on the piston is then

- La partie electronique.- The electronic part.

Quand les lamelles du contacteur sous-verre se rejoignent (CT1) le courant alimente un circuit integre compose de quatre portes (1-2-3-4), sa sortie vers la resistance (R1) et le transistor (T1) est temporise par un condensateur polarise (C1) et par deux resistances (R2-R3) dont l'une est variable (R3) qui permet de regler la duree de la temporisation. Des que cette duree est ecoulee le transistor (T1) devient conducteur laissant passer le courant vers le condensateur (C2) et les deux resistances (R4 et R5) qui ont pour rBle de bloquer momentanement le transistor (T2) afn de permettre au condensateur (C3) de se charger. A son tour le transistor (T2) se debloque actionnant le relais (RL1) qui s'alimente par le condensateur (C:3) ce qui permet de lancer le moteur- reducteur (MR1). Le contacteur (CT2) maintient le courant jusqu'a la  When the glass contactor lamellae meet (CT1), the current feeds an integrated circuit composed of four gates (1-2-3-4), its output to the resistor (R1) and the transistor (T1) is delayed by a polarized capacitor (C1) and by two resistors (R2-R3) one of which is variable (R3) which makes it possible to adjust the duration of the time delay. As soon as this time has elapsed the transistor (T1) becomes conductive letting the current flow to the capacitor (C2) and the two resistors (R4 and R5) which have the role of temporarily blocking the transistor (T2) in order to allow the capacitor ( C3) to charge. In turn the transistor (T2) unlocks activating the relay (RL1) which is supplied by the capacitor (C: 3) which allows the motor-reducer (MR1) to be started. The contactor (CT2) maintains the current until the

Un bouton-poussoir (BP. 1) perrnet de reactiver le systeme.  A push button (BP. 1) allows to reactivate the system.
