Title (EN) GAS-FLOW REGULATING SYSTEM
(FR) SYSTEME DE REGULATION D"UN DEBIT DE GAZ
Abstract: front page image
(EN)In a gas-flow regulating system which continuously controls the opening of an electromagnetic valve, in order to remove the magnetic hysteresis existing in a plunger (3) and yoke members (4, 8) which make up a magnetic path, and to reduce the static friction between the plunger (3) and the yoke members (4, 8), current pulses are alternately supplied to two exciting coils (5, 5") with such a polarity that the direction of the magnetic fields produced by one exciting coil (5) is opposite to that of the other exciting coil (5"), so that the magnetizing direction in the magnetic path is continuously being inverted and the plunger (3) is vibrated.
(FR)Dans un systeme de regulation de debit de gaz qui commande de maniere continue l"ouverture d"une soupape electromagnetique de maniere a eliminer l"hysteresis magnetique existant dans un piston (3) et des jougs (4, 8) qui forment un passage magnetique, et de maniere a reduire la friction statique entre le piston (3) et les jougs (4, 8), des impulsions de courant sont envoyes alternativement a deux bobines d"excitation (5, 5") ayant une polarite telle que la direction des champs magnetiques produits par l"une des bobines d"excitation (5) soit opposee a celle de l"autre bobine d"excitation (5"), de sorte que le sens d"aimantation dans le chemin magnetique soit continuellement inverse provoquant la vibration du piston (3).
