In order to ensure piston rod smoothly starts, needle is flexibly run, the needle is with being equipped with packing ring and close at valve body contact
Seal, the needle at plunger rod contacts with being equipped with double-deck packing ring and double-layer seal rings.
In order that the inwall of valve body, floating piston and body more seals, the valve body, the periphery of floating piston are provided with close
Seal.
In order to realize gas spring rigid locking, the cavity separation of floating piston both sides, floating piston inside and piston rod phase
Sealing ring is housed at even.
The stopping means is the pressure ditch slot rolling being arranged on tube body wall, and bottom land protrudes from inboard wall of tube body, and limitation, which is floated, lives
The displacement of plug, making between each part will not play, it is ensured that the stroke of gas spring meets demand.
The beneficial effects of the invention are as follows：It is a kind of ensure stroke lock gas spring, it compresses, using effect big to latching force
It is good.
