Abstract

UN MECANISMO DE UNA BIELA DE PISTON PARA USAR EN UN MECANISMO DE INYECCION PARA UN CARTUCHO DE INYECCION, QUE SE COMPONE DE UNA HEBRA SIMPLE O MULTIPLE (3) A LO LARGO DE UN SEGMENTO PREDETERMINADO DE SU LONGITUD, A PARTIR DEL CUAL LA HEBRA (3) SE CONVIERTE EN UN SURCO LONGITUDINAL (5) POR CADA HEBRA, DE TAL MODO QUE UN MOVIMIENTO GIRATORIO DE LA BIELA DEL PISTON SE TRANSFORMARA EN UN MOVIMIENTO AXIAL A PARTIR DE DICHA LONGITUD PREDETERMINADA. LA HEBRA (3) TIENE LA FORMA DE UNO O MAS SURCOS HELICOIDALES EN LA SUPERFICIE DE LA BIELA DEL PISTON (1), DICHOS SURCOS (3) SE CONVIERTEN EN SURCOS LONGITUDINALES (5) A PARTIR DE LA LONGITUD PREDETERMINADA. UNA TUERCA (6) SE ACOPLA A LA HEBRA (3), Y SU MECANISMO DE ACOPLAMIENTO CONSISTE DE AL MENOS UNA PROYECCION RADIAL DIRIGIDA HACIA EL INTERIOR (10) PARA CADA HEBRA, DICHA PROYECCION (10) O PROYECCIONES GUIAN LA BIELA DEL PISTON (1)A TRAVES DEL SURCO O SURCOS QUE FORMAN DICHA HEBRA (3).
