Principle of Operation

It is possible to stop at any position and be locked by movement of inner oil(gas).

 

1) In case of having Free Piston

  • Locking
    Because oil of A and B room is shut off by O/C/Pin, Piston is locked.

  • Unlocking
    When Valve Pin (Push Rod) is pushed, O/C/Pin is opened and oil of A and B room comes to move through Orifice pipe, therefore Lock is released. Piston Rod is expanded by pressure of C room gas but it is reduced by pushing force.

  • Relocking
    When force is removed from Valve Pin(Push Rod), O/C/Pin is locked and a state of (1) comes again.

2) In case of no Free Piston

  • Locking
    O/C/Pin shuts off Oil+Gas and Piston is locked.

  • Unlocking
    When Valve Pin(Push Rod) is pushed, Oil+Gas can move through Orifice pipe by opened O/C/Pin and Lock is released. Piston Rod is expanded by pressure of Gas but it is reduced by pushing force.

  • Relocking
    When force is removed from Valve Pin(push Rod), O/C/Pin is locked and a state of (1) comes again.
