Abstract

UN SISTEMA DE MOLDEO DE INYECCION PORTICADO DE VALVULA EN EL QUE LA FUERZA ACTUANTE DESDE UNA PALANCA PIVOTE (118) ES TRANSMITIDA A UNA VALVULA ALRGDA (10) A TRAVES DE UN ANILLO DIVIDIDO (102). LOS DOS SEGMENTOS OPUESTOS (104,106) DEL ANILLO DIVIDIDO (102) SON MONTADOS ALREDEDOR DE LA PARTE ESTRECHA (94) DE LA VALVULA (10) CUANDO ESTA EN LA POSICION RETRAIDA. LOS SEGMENTOS (104,106) SON RECIBIDOS EN UNA ABERTURA CENTRAL (58) EN EL COLECTOR (18), QUE LOS GUARDA EN ENGRANAMIENTO LONGITUDINAL CON LA VALVULA (10) Y RECIPROCAMENTE. EL ANILLO (102) TIENE UN CORTE (114) QUE ENGRANA EL EXTREMO INTERIOR (138) DE LA PALANCA (118). EL ANILLO (102) TIENE UNA PARTE COLLAR (108) QUE SE EXTIENDE DENTRO DEL ALMA DE LA BOCA (12) EN LA POSICION AVANZADA Y DETERMINA LA LONGITUD DE VIAJE DE LA VALVULA (10) ENTRE LAS POSICIONES ABIERTA Y CERRADA.
