Double-acting pneumatic actuators work principle artwork:
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 end 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 cylinderintermediate 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).
Single-acting pneumatic actuators work principle artwork:
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).
