Title (EN) DUAL MODE PNEUMATIC CONTROL SYSTEM
(FR) SYSTEME DE COMMANDE PNEUMATIQUE A DEUX MODES
Abstract:
(EN) This invention relates to a pneumatic control device having an operating mode selecting means for operating in either the manual or automatic modes. Pneumatic pressure is regulated in the manual mode by hand operated leakport, and in the automatic mode by a voice coil or other pressure regulating device. The pneumatic input supply, manual pressure regulating means and voice coil all communicate at a common surface. The mode selecting means slides across this common surface to connect together the pneumatic input supply with one of the selected pressure regulating means.
(FR) Dispositif de commande pneumatique doté d'un moyen de sélection de mode opératoire, destiné à fonctionner soit en mode manuel soit en mode automatique. La pression pneumatique est régulée dans le mode manuel par un orifice d'échappement à commande manuelle, et dans le mode automatique par une bobine mobile ou par un autre dispositif de régulation de pression. L'alimentation d'entrée pneumatique, le moyen de régulation de pression manuelle ainsi que la bobine mobile communiquent tous au niveau d'une surface commune. Le moyen de sélection de mode coulisse sur cette surface commune, afin de relier l'alimentation d'entrée pneumatique à un des moyens de régulation de pression sélectionnés.
