Abstract: The present invention allows the number of components to be reduced and assembly work to be easily performed. A cylinder drive manifold device that constitutes a cylinder drive apparatus is provided with a block-shaped manifold in which a plurality of holes are formed for circulating a fluid used for driving a plurality of fluid pressure cylinders. The manifold is configured such that a plurality of switching valves for supplying a fluid alternately to a first cylinder chamber and a second cylinder chamber of each of the fluid pressure cylinders are attachable. A plurality of check valves and a plurality of throttle valves are incorporated into the plurality of holes of the manifold.

Abstract: A cylinder main body of a fluid pressure cylinder includes a switch valve, a check valve, and a flow path communicating a high pressure air supply source with a head side cylinder chamber and communicating an exhaust port with a rod side cylinder chamber when the switch valve is at a second position. Another flow path communicates the head side cylinder chamber with the rod side cylinder chamber and the exhaust port when the switch valve is at the first position.

Abstract: In a cylinder drive device, a throttle valve and a second check valve are provided between a switch valve and a first cylinder chamber of a fluid pressure cylinder. The cylinder drive device has a flow channel unit which is interposed between a manifold and the switch valve, which allows communication between the throttle valve and the second check valve and switch valve, and which communicates with a plurality of holes in the manifold to allow a fluid to flow to the switch valve.

Abstract: A pressure booster constituting a cylinder apparatus is provided with a first piston and a second piston that are coupled to each other by a rod. A connection member provided to the second piston is configured so as to be displaceable from a connection position to a blocking position as a result of the connection member making contact with a cylinder body when the second piston is displaced in a direction where a boosting chamber contracts, and so as to be displaceable from the blocking position to the connection position as a result of the connection member making contact with the cylinder body when the second piston is displaced in a direction where the boosting chamber expands.
