Working principle of ATS single action actuator
When air pressure come cylinder two side piston chamber from the gas port(A), two-piston move to the side of the cylinder to force spring compress and then two side chamber air is moved out from gas port (B) and at the same time two-piston gear strip with output shaft spin anti-clockwise. Under air pressure and after solenoid valve transferring, two-piston move to the middle of the cylinder and then middle chamber air is moved from the airport(A) and at the same time, two-piston gear strip with shaft spin clockwise. (If piston are installed relative inverse direction when spring-return output shaft are changed to reverse rotation, it would be single action inverse transformation)
