Improved cushion, adjustable friction, characterized in that it comprises embracing pistons of a press-tow covered by a felt layer; all this is mounted on a piston-bearing shaft on the end of which it threads a regulating nut which, like the end of the piston-holder shaft, fits into a housing of the cylinder body; so that, fitted the nut in the housing, acting on the shaft-piston in one direction or another is achieved the approach or accommodation of the pistons in order to deform the press-tow and felt, which effects on the walls of the cylinder a greater or lesser friction.
