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.Improvements introduced in the invention patent 9801770 for "improvements in hydraulic rotating cylinders". The invention consists of improvements over those presented in the main invention patent 9801770, and they have application in the hydraulic rotating cylinders used for the operation of hydraulic tools or work tools. The improvements are intended to make a more optimal lubrication for certain types or applications of these hydraulic rotating cylinders, by means of the provision of independent paths for oil drainage, which make it possible to perform an individual and more regular lubrication of the bearings, and equally constant and simultaneous.
