Abstract

The present buffer system for a fastener driving device includes two cooperating buffer elements (16, 22) located at the bottom (17) of the driving cylinder (2). A first buffer element (16) of hard elastic material rests on the inwardly facing surface of the cylinder bottom (17) in such a manner that at least a portion of the surface (18) of the first buffer element (16) contacting the bottom (17) is movable relative to the bottom (17) of the driving cylinder (2). A second buffer element (22) made of an elastic material softer than the hard elastic material of the first buffer element, rests on the first buffer element.
