Title: Hitoshi Hamano – Innovator in Chain Tensioner Technology

Introduction

Hitoshi Hamano is a distinguished inventor based in Ishikawa, Japan. With a focus on mechanical innovations, Hamano holds two patents that showcase his expertise in chain tensioner technology. His inventions are notable in the automotive and machinery industries, contributing to improved performance and reliability.

Latest Patents

Hitoshi Hamano's latest patents introduce advanced designs for chain tensioners. The first patent describes a chain tensioner featuring a plunger that is slidably fitted into a bottomed cylinder within a housing. The design incorporates a return spring that resiliently urges the plunger in the projection direction. This innovative mechanism allows for the attachment of an engagement clip to the cylinder opening, enabling an engagement portion on the plunger's end to interact with the engagement clip based on the plunger's rotation.

The second patent builds upon this concept by introducing a chain tensioner that includes a biased disabling mechanism. This design involves a plunger housed within a cylinder, along with a return spring. Furthermore, it features a stopper plate with a through-hole for the plunger insertion and a biasing member that restricts the movement of the plunger. By applying hydraulic pressure from an engine, the design allows the plunger to move freely, reducing the inclination caused by the biasing member.
