PROBLEM TO BE SOLVED: To provide a piston cylinder device having a closing valve with a leakage factor as small as possible. SOLUTION: A back side of a packing 17 is supported by a slider 11. In the slider 11, a discharge flow space 25 is formed with a valve seat 19a, 19b, 19c. The discharge flow space 25 has a discharge flow port 27 large enough to enable discharge flow without a throttle and to impede the forming of dynamic pressure in the discharge flow space 25. |
