Abstract
Device applicable to machines used for rock drilling that serves to apply a constant pressure on the drilling tool characterized on the principle that a translational engine started at each end of the cylinder stroke by the intervention of an operating valve automatic causes a movement of advance of the cylinder and the group of rotation that it is solidary, allowing a retinado and the continuation of the pressure on the tool, whatever the length of the guide column that supports the group of perforation.
