Locking Gas Spring Specification



A locking gas spring incorporates a mechanism to enable the rod to be locked at any point in its travel. This mechanism is actuated by a plunger that protrudes from the rod. When this plunger is depressed the rod is free to operate as normal. When the plunger is released, which may be at any point in the stroke, the rod is locked in that position. Shuangyuan offers three types of locking gas springs, which have the following characteristics when locked:

Flexible Good resistance to rod being pushed of pulled
Rigid in tension Rigid when rod is being pulled, high resistance to rod being pushed
Rigid in compression High resistance to rod being pulled, rigid when rod is being pushed

All three types of locking springs have the same locking mechanism. This locking mechanism operates when the plunger rod is depressed by opening a valve in the piston. When the plunger rod is released the valve closes and the passage of oil or gas is prevented, locking the piston in that position.

Release valve: Both flexible and rigid in tension gas springs can be supplied with a release valve, which allows the installer to reduce the force. This release valve also allows SY to easily and economically recharge the gas spring should too much gas be released.

  3. Relocking
    When force is removed from Valve Pin(Push Road),O/C/Pin is locked and a state of (1) comes agian.
