Abstract
UNA VALVULA (1) DE CORREDERA ROTATIVA PARA DIRECCION ASISTIDA DE VEHICULOS EN UN TALADRO (5) DE VALVULA DE UNA CAJA (2), DISPONE DE UN CURSOR (4) ROTATIVO LIGADO A UNA CONEXION (23) DE EJE DE DIRECCION. UN CASQUILLO (7) DE CONTROL PUEDE OSCILAR SOBRE UN ANGULO LIMITADO EN UN TALADRO (6) AXIAL DEL CURSOR (4) ROTATIVO. EL CURSOR (4) ROTATIVO DISPONE DE RANURAS (20) LONGITUDINALES DE CONTROL PUESTAS EN SU TALADRO (6) AXIAL QUE COOPERA CON LAS RANURAS (21) LONGITUDINALES DE CONTROL SOBRE LA OTRA SUPERFICIE DE LA CARCASA DEL ENCASQUILLADO (7) DE CONTROL. EL ENCASQUILLADO (7) DE CONTROL INTERNO SE FABRICA MEDIANTE UN PROCESO DE MOLDEO SIN CORTE Y PUEDE TENER DE ESTA FORMA DIMENSIONES RELATIVAMENTE PEQUEÑAS. TANTO LAS RANURAS (21) LONGITUDINALES DE CONTROL, COMO LOS BORDES DE CONTROL DEL ENCASQUILLADO (7) DE CONTROL, PUEDEN SER FABRICADOS MEDIANTE UN PROCESO, POR EJEMPLO MEDIANTE MOLDEADO EN FRIO. GRACIAS A LAS DIMENSIONES RELATIVAMENTE PEQUEÑAS DEL ENCASQUILLADO (7) DE CONTROL, LA VALVULA (1) DECORREDERA ROTATIVA COMPLETA PUEDE SER MUY COMPACTA.
