Abstract (en)
[origin: EP0623425A1] The powered wrench has a casing (10) consisting of a head part (11) and a drive part (12). The drive part (12) contains a cylinder bush (21) which is inserted into the casing (10) from the side facing away from the head part (11). A pressure channel which is connected to a hose connection (41) consists of a longitudinal bore (45) which runs in the wall of the cylinder bush (21) in order to supply the rear cylinder (36) with the high pressure required. As a result, it is avoided that the casing (10) is additionally subjected to the hydraulic pressure in the region of the support. In the event of the pressure line rupturing, the casing (10) still holds the cylinder bush (21) together. <IMAGE>
