Title: Innovations by Hideo Teruyama

Introduction

Hideo Teruyama is a notable inventor based in Shobu, Japan. He has made significant contributions to the field of gear pumps and motors, holding a total of six patents. His work focuses on enhancing the efficiency and reliability of these mechanical systems.

Latest Patents

One of Teruyama's latest patents is a gear pump or motor with serrated grooves on the inner wall for break-in. This innovation aims to prevent a decrease in volumetric efficiency when the gear pump or motor operates at varying temperatures. The design includes a housing made of ferrous material, which matches the gears, and features numerous serrated grooves on the low-pressure side of the inner wall. This configuration allows for a smooth break-in operation, as built-up edges on the gear teeth can drop off due to impact forces, ensuring optimal performance.

Another significant patent by Teruyama is a seal mechanism in gear pumps or motors. This mechanism involves a pair of engaging gears, with at least one side surface sealed by a pressure plate that is movable along the shaft. The pressure plate is divided by a seal member shaped like a figure '3', creating low and high-pressure zones. This innovative design prevents liquid leakage by pressing the seal member against the inner wall surface of the gear housing during operation.
