Abstract
Perfeccionamientos en mecanismos de accionamiento de válvulas, para válvulas de motores de combustión interna, cuyo mecanismo comprende un ajustador automático de la holgura entre dos componentes del mecanismo, cuyos componentes tienen hilos de rosca en cooperación que presentan un juego libre axial predeterminado recibiendo los componentes carga de resorte uno con respecto al otro en sentido opuesto a la transmisión de las fuerzas de accionamiento de la válvula entre los componentes de modo que, cuando no se transmite fuerza de accionamiento de la válvula, la carga del resorte obliga a ponerse en contacto los hilos de rosca y produce rotación relativa de los componentes por lo que adoptan posiciones de rotación, de forma que la holgura en el mecanismo es igual al juego axial en el hilo de rosca, caracterizados porque el hilo de rosca presenta una alta fricción en una dirección de carga axial comparada con la fricción en la dirección opuesto de carga axial, y porque las fuerzas de accionamiento de la válvula se transmiten entre los hilos de rosca en la dirección de mayor fricción, por lo que la fricción sirve para evitar la rotación relativa entre los componentes durante el accionamiento de la válvula.
