AI Technical Summary
Technical Problem
In existing turbocharger pneumatic actuators, the piston rod experiences significant extension and retraction vibrations, leading to unstable valve opening and closing.
Method used
A guide block and a guide sleeve are provided between the piston rod and the housing. The guide block is provided with a ball groove and a ball, and the inner wall of the guide sleeve is provided with a guide groove. The piston rod is stably guided by the cooperation of the ball and the guide protrusion.
Benefits of technology
This improves the extension and retraction stability of the piston rod, ensures the stability of valve opening and closing, and avoids instability caused by vibration.
