Characteristics of the Product No step adjustment STOP and LOCKING can be set at an arbitrary position by opening and locking the internal oil (gas). Easy operation Operation is easy since opening and locking can be done by pressing the valve pin. Smooth operation The movement is smooth because of an oil buffing, and the low elasticity index provides pleasant feeling. Compact It is easy to install as it is light in weight due to its reduced length and compact external mirror. Simple installation It is simple to install due to its convenient configuration.
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.
