Abstract

Mejoras introducidas en la patente de invención 9801770 por "perfeccionamientos en los cilindros giratorios hidráulicos". La invención consiste en unas mejoras sobre las presentadas en la patente de invención principal 9801770, y tienen aplicación en los cilindros giratorios hidráulicos empleados para la actuación de herramientas o útiles hidráulicos de trabajo. Las mejoras tienen por objeto realizar un engrase más óptimo para determinados tipos o aplicaciones de estos cilindros giratorios hidráulicos, mediante la disposición de vías independientes para el drenaje de aceite, que posibilitan realizar un engrase individualizado y más regular de los rodamientos, e igualmente constante y simultáneo.
