Working Principle
When the machine running,high-pressure air(or Pressurized gas) enter into the air valve through handles by a running air valve which will lead pressure gas into front cavity and back cavity of the cylinder body,piston do high-speed raptlywhich pushed by pressure air,the waste air exhaust from the mouth.
Strike stroke
When the operation Valves turn to the revolve position of machine,pressure air enter into back cavity of cylinder body from the operation hole (1)through air room of handles (2) the hole of ratchet(3) the air path of valve's cover(4) at this time valve attached with valve's cover,result of closing the air enter way of the return stroke while open the air enter way of the push stroke,ring-like air roon(6)and the hole of valve.And thus to push piston moved forward,When the piston's end surface(A)jump over the push hole of valve which located in the back cavity,pressure air push valve to charge direction through crescent moon-like through(8) and hole(5)the back cavity of air cylinder stop entering air.
When the piston open the exhaust hole,the pressure air of back cavity inject air into the hole of exhaust hole from crescent mon-like through(9) at this moment,Piston and the strike stroke by strike the back of checking,strike stroke(fig.1)
