Dish spring group (4) is equipped with in cylinder barrel of the present utility model (1) lining, and dish spring group (4) adopts involutory form to form.
Cylinder barrel of the present utility model (1) lining constitutes three hydraulic cavities (35), (38), (39) by piston (5), piston (6).
On piston of the present utility model (5) and the piston (6) damping hole (33), (37) are arranged respectively.
The outer garden dimension D of orienting sleeve of the present utility model (2)
1And the outer garden of piston head (25) dimension D of piston rod (3)
