Abstract (en)
[origin: EP0460592A1] The hydraulically impulsed wrench has a rotationally driven impact mechanism with an output shaft (23) for a screwing tool. The output shaft (23) possesses lamellae (33 to 36) which are distributed at angular distances of 90 DEG over the circumference, are adjustable approximately radially outwards and, in the case of a 360 DEG -rotation of the output shaft (23), bear, in one position, sealingly on sealing strips (54, 55) of the impact-mechanism housing (5). Two diametrically opposite lamellae (33, 34) have follower members, through which they are adjustable in a positively controlled manner in cooperation with control paths (46, 48). Owing to the positive control of these lamellae (33, 34), the sealing strips (54, 55) can be simply manufactured. All of the lamellae (33 to 36) can additionally be arranged symmetrically to the axis of the output shaft (23), so that the output shaft (23) and their bearing points are not unevenly loaded on generating the angular momentum. <IMAGE>
