   »   Double acting pneumatic actuator Working Principle: 

Description:

 

 

When air pressure from the port (2) into two piston cylinder between central cavity, make the two ends to the cylinder piston separation direction, both ends air cavity air through the port (4) discharge, and at the same time,make the two piston rack synchronous drive the output shaft (gear) counter-clockwise. And air pressure from the port (4) into the cylinder ends air cavity, two pistons to cylinder intermediate direction, and the middle gas cavity air through the port (2) discharge, and at the same time, make the two piston rack synchronous drive the output shaft (gear) clockwise. (if the piston relative inverse direction installation, output shaft that into reverse rotation)
