CE DISPOSITIF COMPREND UN CONDUIT D'ECOULEMENT DE FLUIDE AYANT UN SIEGE. UNE MEMBRANE 12 EST DISPOSEE DE FACON QUE L'UNE DE SES FACES PUISSE VENIR EN APPUI SUR LEDIT SIEGE 14 POUR FERMER LE CONDUIT. UNE CHAMBRE 19 EST DELIMITEE EN PARTIE PAR L'AUTRE FACE DE LA MEMBRANE 12. EN SERVICE LA MEMBRANE 12 EST MAINTENUE ECARTEE DU SIEGE 14 PAR LA DIFFERENCE DE PRESSION EXISTANT ENTRE LA CHAMBRE 19 ET LE CONDUIT. DES MOYENS 30, 31 DE MISE A L'ATMOSPHERE OUVRENT LA CHAMBRE 19 SUR L'ATMOSPHERE ET DES MOYENS SONT PREVUS POUR FERMER LESDITS ORIFICES DE MISE A L'ATMOSPHERE. UN ORGANE D'ACTIONNEMENT 26 COOPERE AVEC LADITE MEMBRANE LORSQUE REGNE LADITE DIFFERENCE DE PRESSION. LORSQUE LA DEPRESSION REGNANT DANS LE CONDUIT DIMINUE LE MOUVEMENT DE LA MEMBRANE 12 ASTREINT L'ORGANE D'ACTIONNEMENT A DEPLACER DES MOYENS DE FERMETURE DE SORTE QUE LA CHAMBRE EST MISE A L'ATMOSPHERE ET QUE LA MEMBRANE VIENT EN APPUI CONTRE LE SIEGE 14. THIS DEVICE INCLUDES A FLUID FLOW DUCT WITH A SEAT. A MEMBRANE 12 IS ARRANGED IN A WAY THAT ONE OF ITS FACES CAN COME TO LESS ON ITS SEAT 14 TO CLOSE THE DUCT. A CHAMBER 19 IS BOUNDED IN PART BY THE OTHER SIDE OF THE MEMBRANE 12. IN SERVICE, THE MEMBRANE 12 IS KEEPED SEPARATE FROM THE SEAT 14 BY THE PRESSURE DIFFERENCE EXISTING BETWEEN THE CHAMBER 19 AND THE DUCT. Means 30, 31 of airing open the chamber 19 onto the atmosphere and means are provided for closing the said air vents. AN ACTUATOR 26 COOPERATES WITH THE SAID MEMBRANE WHEN THE SAID PRESSURE DIFFERENCE REIGNS. WHEN THE LOW PRESSURE IN THE DUCT DECREASES THE MOVEMENT OF THE MEMBRANE 12 STRESSES THE ACTUATOR TO MOVE CLOSING MEANS SO THAT THE CHAMBER IS PUT INTO THE ATMOSPHERE AND THE MEMBRANE COMES INTO PRESS AGAINST THE SEAT 14.

DIAPHRAGM VALVE CONTROLLED BY A PILOT VALVE

Domestic water tap with push button control - permanent magnet is pushed down to open orifice and second push raises magnet

Depressing the button (14) lowers the magnet (29) whose radial projections (30) slide in grooves (26) in the head (11) until free (31). It is then turned by teeth (28) in the button and locks between two grooves. A piston (22), pulled up by magnetic attraction, releases a plunger (21) sealing a flexible diaphragm (20) dividing the delivery chamber in two (18, 19). Water introduced into the upper part (18) through a bypass (15) flows into the outlet (16), the pressure drop allowing the inlet water to raise the diaphragm and discharge. Pressing the button again turns the magnet; it returns and a spring (23) shuts off the water flow.
