Abstract

Un inyector de combustible del tipo utilizado para inyectar combustible en un cilindro en un motor de combustión interna cuando se instala en el mismo, teniendo el motor una fuente de suministro de combustible a alta presión, que suministra combustible al citado inyector, y un retorno de combustible a baja presión que retira el combustible del citado inyector, comprendiendo el citado inyector: un cuerpo (24¿) de inyector, que define una cavidad interior (46¿), incluyendo la citada cavidad interior: una región de control (16¿) de volumen variable; una región (48¿) de combustible a alta presión, conectada para el paso de fluidos, a la fuente de suministro de combustible a alta presión, una región (21¿) de boquilla con aberturas, conectada para el paso de fluidos entre la fuente de suministro de combustible a alta presión y el cilindro del motor, cuando el citado inyector se instala en el motor, y una región (52¿) de combustible a baja presión, conectada para el paso de fluidos entre la citadaregión de control y el retorno de combustible a baja presión; una válvula de aguja (14¿) dispuesta, al menos parcialmente, en el interior del citado inyector, para realizar un movimiento entre las posiciones primera y segunda, teniendo la citada válvula de aguija (14¿) una porción de inyección (55¿) que bloquea el flujo de combustible a través de la citada región (21¿) de boquilla cuando la citada válvula de aguja (14¿) se encuentra en la citada primera posición, y permite el flujo de combustible a través de la citada región de boquilla cuando la citada válvula de aguja (14¿) se encuentra en la citada segunda posición.
