Working Principle
The Pneumatic Angular Stroke Actuator operates on a sophisticated yet efficient mechanism, enabling precise rotary motion control:
1. Double-Acting Operation:
- Compressed air enters the first piston chamber, driving the piston to move linearly.
- This motion is transferred to the rack and pinion system, which converts it into rotary motion.
- The actuator achieves the desired angular stroke (e.g., 90 degrees) with high precision.
2. Return Mechanism:
- Compressed air is directed to the second piston chamber, driving the piston in the opposite direction.
- The rack and pinion system reverses the motion, returning the actuator to its original position.
3. Position Feedback:
- Integrated sensors or encoders provide real-time feedback on the actuator's position, ensuring accurate control and repeatability.
