ABSTRACT:
Disclosed is a unique force generating mechanism which is easily adapted for use in a compact lightweight tool requiring high work forces. The mechanism includes a force generating member disposed within an actuation chamber where either pneumatic or hydraulic fluid pressure is allowed to bear against a relatively large ram surface causing a deflection of the ram in a first direction and translation of the ends of the ram in a second direction substantially perpendicular to the first direction. A working force, larger than the force of the fluid bearing on the ram surface, is thereby generated along this direction of translation.
