Patent

CA 2182632

A pulse tool, especially a nutsetter, comprises a pulse unit including a hydraulic cylinder driven by a motor, and a driven shaft supported in said hydraulic cylinder. Two seal rollers are supported in radial grooves of the driven shaft. The rollers are power-operated towards the inner wall of the cylinder. The seal rollers are simultaneously in contact only in a single rotary position of the cylinder with seal strips that project relative to the inner wall of the cylinder so as to produce an angular momentum. To simplify the structure of the pulse tool and to extend the period of use at the same time, the radial groove which receives the seal roller serving as a compensating roller comprises a lift delaying means for the limited centrifugal movement of said compensating roller.
