Title: Tetsurou Maruyama: Innovator in Hydraulic Transmission Technology

Introduction

Tetsurou Maruyama is a distinguished inventor based in Saitama, Japan, known for his innovative contributions to hydraulic transmission systems. With a total of four patents to his name, he has significantly advanced the field through his unique inventions that optimize performance and durability in hydraulic applications.

Latest Patents

One of his latest patents is the "Hydraulic Transmission Apparatus with Lockup Clutch." This invention features a sophisticated design that includes a pump impeller, a turbine runner, a side cover, a lockup clutch, a clutch piston, and a resilient member, among other components. The innovation ensures that the transmission capacity of the lockup clutch, driven by the resilient member's biasing force, is smaller than the torque absorption capacity of the pump impeller when the engine is idling. This design allows the clutch piston to remain in a predetermined position, enhancing the overall efficiency of the hydraulic transmission system.

Another significant patent is the "Fluid Transmitting System with Lock-Up Clutch." This system includes a lock-up clutch positioned between a side cover connected to a pump impeller and a turbine runner. It utilizes a Belleville spring to bias the clutch piston towards engagement. The invention incorporates a limiting mechanism that maintains a constant retraction of the clutch piston, preventing excessive deformation of the Belleville spring during operation. This innovation not only preserves the spring's inherent characteristics but also improves its durability.
