Abstract

Válvula de recirculación de gases de escape (10), que está diseñada como válvula de 3 vías de tal manera que mediante un único elemento de válvula (12) puede interrumpirse un flujo de gases de escape y puede estrangularse al menos un flujo de aire fresco, en la que mediante el elemento de válvula (12) puede interrumpirse además el flujo de aire fresco, caracterizada porque el conducto de recirculación de gases de escape (16) presenta una sección transversal de flujo menor que la del conducto de aire fresco (18) y, para la posición que interrumpe totalmente el flujo de aire fresco, está previsto en la zona de un eje de pivotado (14) del elemento de válvula (12) un tope (26).Exhaust gas recirculation valve (10), which is designed as a 3-way valve in such a way that by means of a single valve element (12) a flow of exhaust gases can be interrupted and at least one flow of fresh air can be throttled , in which the flow of fresh air can be interrupted by means of the valve element (12), characterized in that the exhaust gas recirculation duct (16) has a smaller cross-sectional flow than that of the fresh air duct (18 ) and, for the position that completely interrupts the flow of fresh air, a stop (26) is provided in the area of a pivot shaft (14) of the valve element (12).
