Abstract

UNA BOMBA DE INYECCION DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA QUE COMPRENDE UN EMBOLO Y UN PISTON DISTRIBUIDOR (21) AL QUE SE IMPARTE UN MOVIMIENTO VERTICAL GIRATORIO MEDIANTE UN DISCO EXENTRICO (12). EL DISCO EXCENTRICO (12) ESTA ACOPLADO, EN LA DIRECCION DEL GIRO, A UN EJE DE TRANSMISION (11) Y TRABAJA CONJUNTAMENTE CON SUS LEVAS FRONTALES (14) SOBRE RODILLOS (16) GUIADOS SOBRE UN, ESENCIALMENTE, ESTACIONARIO ANILLO DEL RODILLO (17). LA VELOCIDAD DE GIRO Y LA POSICION ANGULAR DEL EJE DE TRANSMISION (11) SE DETERMINA MEDIANTE UN SENSOR DE POSICION ANGULAR (34) . ESTE SENSOR (34), COMPRENDE UN DETECTOR (37) ASEGURADO AL EJE DE TRANSMISION (11) DE FORMA QUE PERMANECE FIJO DURANTE LA ROTACION Y QUE EXAMINA EL VOLANTE DEL SENSOR (36). EL ANILLO DEL RODILLO (17) ESTA MONTADO SOBRE EL EJE DE TRANSMISION (11) MEDIANTE UN RODAMIENTO DE BOLAS (41) DE FORMA QUE ELIMINA LOS MOVIMIENTOS, RELATIVOS, INCONTROLADOS ENTRE EL DETECTOR (37) Y EL VOLANTE DEL SENSOR (36) Y, TANTO LA POSICION ANGULAR COMO LA VELOCIDAD DE GIRO DEL EJE DE TRANSMISION (11) PUEDEN DETERMINARSE CON ALTA PRECISION.
