Abstract

Mejoras introducidas en la patente principal nº 451.043 por: "Instalación de mando del medio de presión en las servodirecciones, en especial para vehículos automóviles", con distribuidor giratorio, que posee unas ranuras longitudinales que en el sentido axial se extienden por la superficie lateral cilíndrica exterior del mismo, así como con un casquillo de distribución que va provisto de unas ranuras longitudinales, que en sentido acial se extienden por la superficie lateral cilíndrica interior de éste casquillo y que actúan en conjunto con las ranuras longitudinales del distribuidor giratorio, terminando las ranuras longitudinales por delante de los extremos de ésta distribuidor giratorio y del casquillo de distribución, estando alojado el distribuidor giratorio de forma rotatoria por los dos extremos del mismo y por medio de dos rodamientos dentro del casquillo de distribución, caracterizadas porque el sistema de las ranuras longitudinales del distribuidor giratorio posee para cada dirección de distribución tan sólo un bisel de mando.
