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.

Abstract: A fluid pressure cylinder comprises a rod insertion hole formed in a piston member, an auxiliary rod provided to a head side wall member so as to be inserted into the rod insertion hole, an open/shut valve mechanism for detection, and a fluid passage that is opened and shut by the open/shut valve mechanism. The open/shut valve mechanism includes a valve body reception hole formed in the auxiliary rod, a valve body that is movably held in the valve body reception hole and that has a recessed engagement portion on its external peripheral portion, and a spherical body mounted on the auxiliary rod so as to engage with the recessed engagement portion; when the piston member has reached a set shifting position, the valve body is changed over to the closed position or to the opened position due to cooperation between the spherical body, the recessed engagement portion, and the inner peripheral wall portion of the rod insertion hole.
