Abstract
A hydraulic strut device for mines, in which an annular space in transverse section, comprised between the inner strut and the outer strut, serves as an aid for the desentibado, and in which the limiting piston of the annular space is provided with joints in the upper and lower ends, characterized in that a valve governed by an impeller rod, which serves for the limitation of the extension movement through mechanical load, and for the limitation of the load, is disposed between the inner and outer posts. pressure in the annular space, through load as a function of pressure.
