Working principle of double piston cylinder

The working principle of double piston cylinder is as follows.

1, alternately supply air from both sides of the piston, and output force in one or two directions.

2. When the piston moves to the right under the push of compressed air, the gas in the right chamber of the cylinder is exhausted through the plunger hole 4 and the air hole 8 on the cylinder head. If the pressure generated by compressed gas can be balanced with all the energy possessed by the piston movement, it will achieve the buffering effect and make the piston move smoothly at the end of the stroke without impact.
