Title: The Innovations of Ko Chiba
Introduction
Ko Chiba is a notable inventor based in Kashiwazaki, Japan. He has made significant contributions to the field of piston ring assemblies, holding a total of 2 patents. His work focuses on enhancing the performance and reliability of piston rings in various applications.
Latest Patents
Chiba's latest patents include innovative designs that improve the functionality of piston ring assemblies. One of his patents is for a "Corrugated expander for piston ring assembly." This invention features an annular expander with vertically extending notches, which are formed on either side of a plurality of circumferentially spaced upstanding tabs. These tabs project from the top and bottom edges of the expander, allowing for elastic deformation when subjected to strong forces from the cylinder wall. This ensures that the side rails remain in contact with the cylinder wall during the reciprocation of the piston.
Another significant patent is the "Spacer and expander member for holding and biasing piston ring rails." This invention includes a pair of rails that engage with the cylinder wall, along with a spacer and expander member designed to hold and expand the rails. The member features a corrugated base with arms that extend alternately upwardly and downwardly, providing an improved resilient spring-like action to the rails supported on the crowns.
