Abstract
The fluid clamp apparatus includes: a sliding piston member that vertically partitions its cylinder bore; first and second fluid pressure operation chambers; a fluid passage that, during an upward light-load stroke of the piston member, causes the back pressure in the second fluid pressure operation chamber to be received by the output rod to advance the output rod; a force multiplying mechanism that, during a heavy-load stroke of the piston member, multiplies the force acting on the piston member and transmits this force to the output rod; and a link mechanism that, during unclamping lowering operation of the piston member, links together the output rod and the piston member after lowering by a predetermined stroke amount.
