Abstract

Mejoras en el objeto de la patente 452.805, por "perfeccionamientos en los sistemas de carburación para motores de combustión interna", del tipo que comprende, en su conducto de admisión, corriente arriba de un órgano de estrangulación principal accionado por el conductor, un órgano de estrangulación auxiliar que se abre automáticamente y progresivamente a medida que aumenta el caudal de aire que atraviesa dicho conducto y que manda un órgano dosificador que regula el caudal de combustible aspirado hacia un orificio de descarga en el conducto de admisión desde una cuba de nivel constante, caracterizadas porque el órgano dosificador comprende una válvula electromagnética entre la cuba de nivel contante y el orificio y mandada por unos impulsos eléctricos periódicos proporcionados por un circuito electrónico, comprendiendo un componente, tal como un potenciómetro, mandado por los desplazamientos del órgano de estrangulación auxiliar de manera que el caudal de combustible por unidad de tiempodepende de la posición del órgano de estrangulación auxiliar, y porque el orificio de descarga está situado sensiblemente en el cuello de un venturi formado por una porción estrangulada del conducto de admisión y por el órgano de estrangulación auxiliar, previsto para desplazarse de forma que mantenga una depresión aproximadamente constante en el cuello e inmediatamente corriente abajo de dicho órgano.
