Claims7
A cylinder device comprising:
- a housing;
- a piston inserted in the housing, the piston being configured to move in an axial direction to a lock side and to a release side;
- a first detection valve provided to the housing, the first detection valve being configured to detect an operational state of the piston;
- a second detection valve provided to the housing, the second detection valve being configured to detect the operational state of the piston;
- an air supply passage provided to the housing, the air supply passage being configured to supply air either to the first detection valve and then to the second detection valve or to the second detection valve and then to the first detection valve;
- and
- at least one air passage provided to the housing, the air passage communicatively connecting the first detection valve and the second detection valve to each other in series, and the air passage being configured to supply air either from the first detection valve to the second detection valve or from the second detection valve to the first detection valve,
- wherein the second detection valve among the first and second detection valves is configured as a throttle detection valve including a throttle passage.
