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: A fluid pressure cylinder driving device includes a switch valve, a high pressure air supply source, an exhaust port and a check valve. When the switch valve is at a first position, a head side cylinder chamber communicates with the high pressure air supply source, and a rod side cylinder chamber communicates with the exhaust port. When the switch valve is at a second position, the head side cylinder chamber communicates with the rod side cylinder chamber via the check valve, and the head side cylinder chamber communicates with the exhaust port.

Abstract: In a cushion mechanism of a gas cylinder, when the pressure of a gas in a first pressure chamber is less than or equal to a prescribed pressure, a valve body cuts off communication between the upstream side and downstream side of a discharge flow passage by mean of the biasing force of a spring member. In addition, when the pressure of the gas exceeds the prescribed pressure, the valve body is displaced to the downstream side of the discharge flow passage against the biasing force, thereby enabling communication between the upstream side and the downstream side of the discharge flow passage.

Abstract: In a fluid circuit for an air cylinder connected to a switching valve provided with exhaust ports, a head-side pressure chamber is connected to the switching valve by a first pipe, and a rod-side pressure chamber is connected to the switching valve by a second pipe. A first restrictor is disposed at a connection point between the first pipe and the switching valve or in the vicinity of a first output port of the switching valve, and a second restrictor is disposed at a connection point between the second pipe and the switching valve or in the vicinity of a second output port of the switching valve.

Abstract: A gas cylinder includes supply passages for supplying, to an accommodation chamber, a part of gas supplied to a second port. When the pressure in a first pressure chamber is equal to or lower than a prescribed pressure, a valve element closes a discharge flow passage by the biasing force of a spring member and the pressure in the accommodation chamber. When the pressure in the first pressure chamber exceeds the prescribed pressure, the valve element is moved by the pressure in the first pressure chamber, against the biasing force and the pressure in the accommodation chamber, to thereby open the discharge flow passage.
