Abstract

Una unidad de válvula para regular el caudal de un gas combustible alimentado a través de un conducto (3) de suministro, comprendiendo la unidad: una servo-válvula (4) que posee un elemento (5) de cierre controlado por un diafragma (8), estando el diafragma sometido a la presión de suministro del gas por un lado, y a una presión de control establecida en una cámara (9) de control de la servo-válvula por el otro lado; un dispositivo regulador de presión asociado a la servo-válvula (4), y que comprende una válvula (10; 51) de regulación para controlar la presión de control de la cámara (9) de control; medios reguladores adicionales para modular la presión de suministro y/o el caudal de salida de gas a través del conducto (3) de suministro en función de un control externo, actuando los medios reguladores adicionales alternativamente sobre el dispositivo regulador de presión o sobre medios (53) para estrangular el conducto de suministro con el fin de modular la presión de alimentación, o para modular el caudal suministrado a través del conducto (3) de suministro, respectivamente, y medios actuadores para los medios reguladores adicionales, que se caracteriza porque los medios actuadores comprenden un motor (32) reversible que posee un rotor (31) conectado a un acoplamiento de tornillo, con tornillos (28, 29; 58, 57) macho y hembra que actúan sobre el dispositivo regulador de presión o sobre los medios de estrangulamiento, para el control operativo de los mismos.
