» Aluminum alloy single acting pneumatic actuator

Single acting working principle:

 

 

 

 When air pressure from the port (2) into two piston cylinder between midplane, make the two ends to the cylinder piston separation direction, forcing both ends of the spring compression, both ends air cavity air through the port (4) discharge, and at the same time, make the two live plug rack synchronous drive the output shaft (gear) counter-clockwise. In the air pressure after solenoid valve reversing, cylinder two piston in the spring under the stretch to intermediate direction, and the middle gas cavity air from port (2) exhaust out, at the same time make the two piston rack synchronous drive the output shaft (gear) clockwise. (if the piston relative inverse direction installation, spring reset output shaft that into reverse rotation)
