Zusammenfassung:	The power wrench comprises a housing (10) with a rearward housing member (12) which forms a protection against bursting for the hydraulic cylinder (27) arranged within the housing member (12). Through a joint (38, 40) and self-aligning, the piston (35) acts upon the lever (18) which is supported coaxially to the ring (14). The lever (18) comprises a ratchet element (17) being supported at the lever (18) by a semisperical pressure member (20). The power wrench can be submitted to extremely high hydraulic pressures without a danger to the environment.
