Title: The Innovations of Inventor Ming Liu

Introduction

Ming Liu is a notable inventor based in Westmont, IL (US), recognized for his contributions to fluid-actuated cylinder technology. He holds 2 patents that showcase his innovative approach to engineering challenges. His work has significantly impacted the design and functionality of piston and cylinder devices.

Latest Patents

Ming Liu's latest patents include the "Double Rod End Cylinder with Split Ring Coupling" and the "Cylinder Locking Apparatus." The Double Rod End Cylinder features a fluid-actuated cylinder that incorporates a piston rod with a circumferential groove. A split ring, designed with specific linear expansion properties, is cooled and then expanded to create a secure fit within the groove, preventing any axial or rotational movement. This design enhances the performance and reliability of the piston rod assembly within the cylinder housing.

The Cylinder Locking Apparatus is another innovative creation by Liu. It includes a locking plunger connected to the piston, which engages with a series of radially movable ball bearings. As the piston moves, the ball bearings interact with a spring-loaded locking plug, securing the piston and piston rod in place when fluid pressure is absent. This mechanism allows for safe operation and easy unlocking of the piston for movement.
