There is great contact area with inboard wall of cylinder block, can it is efficient in the heat that generates of wall friction import water cooling tube；And water cooling fills
The outer wall set has great contact area with outer wall of cylinder block again, can the heat of water cooling tube importing outer wall be passed through heat dissipation in time
Device dissipates；Hollow bolt pipe is in for fixing while also having the function of heat conducting pipe, water cooling plant outer wall simultaneously
On heat timely imported in radiator by hollow bolt pipe, further increase radiating efficiency；By in cavity bottom
Buffer unit is set, and buffer unit is set as the different buffer spring of multiple height, piston, can successively when close to bottom of chamber portion
The spring of different height is contacted and squeezes, spring gradually increases the resistance of piston；Both effectively prevented piston to cylinder body
It is formed and is hit, and effectively avoid piston deceleration stress caused by piston rod suddenly, cylinder body and work can be effectively protected
Stopper rod improves its service life；By the way that positioning strip is arranged on the piston rod, the stabilization of piston rod during the motion can be improved
Property, reduce non-axial force, improves service life；By being further provided with the cylinder cap of radiating groove, increase and sky are also played
Gas contact area, the effect that auxiliary cylinder block radiates, further improves service life.
