Coaxial in the middle part of chamber, the axial other end of exhaust outlet main body to be formed with an air-vent, the diameter of the air-vent is less than steam vent, and
Internal thread is formed with air-vent；Periphery is formed with a spacing ring in the middle part of exhaust outlet main body, after the axial side of the spacing ring is held out against
End cap outer wall.
Moreover, the axial opposite side of spacing ring is formed with an annular groove.
Moreover, the rear end cap main body co-axial seal of this high-voltage oil cylinder is packed in axial one end of cylinder body, cylinder body is being installed
The coaxial end for being embedded with piston rod in coaxial only one of which limited support hole, limited support hole in the middle part of the rear end cap main body of side
Portion, the internal orifice in limited support hole and the contact position of piston rod are formed with the outer wall that sealing bulge loop is fitted close piston rod, spacing branch
Support inside hole is cushion chamber；Limited support hole is blind hole structure, is formed with a steam vent in the bottom in limited support hole, the steam vent
Inside it is fixed with an exhaust outlet for leading to outside.
Advantage of the present utility model and good effect are：
The utility model reasonable in design, composition is simple and reliable, and fault rate is low, and the cavity of piston both sides is to have bar
Chamber, it is ensured that lifting activity flexibility on the premise of sealing, exhaust outlet balance inner and outer air pressure, enhancing action accuracy, lifting member
The functional reliability and whole service life of part.
