<p>The driver, by means of the lever (1) of the setting device stirruped to the frame which drives on steel cable (2), makes to rotate a bush (3) into the other bush (4) of the tubolar arm (5). To the first bust (3) is tied the first end of a band spring (6) the other end of which is tied to the rigid bush (4). By means of said movement is actuated the screwing or the unscrewing of rod (7) into a bush (9) which realizes the loading or the releasing of a spring (10) stabilized between a beating point (11) and a holed piston (12) to which end (13) is interposed a plastic ring (14) making to adjustable shutter. The spring (10) loading or releasing makes easy the contrast by the tight or not crossing of the oil from the first chamber (15) to the other one (16). By means of the toothed lever (1) of the setting block (26) with chase (27) which supports it to the cycle frame, on the base of a pre-arranged register value scale, is actuated the damping effect setting by the bosh (3) through the valve (28) for the input or not of the air acting the oil compressione. <IMAGE></p> |
