Title: Masato Yamada: Innovator in Fluid Fan Coupling Technology
Introduction
Masato Yamada is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of fluid fan coupling technology, holding a total of 3 patents. His innovative designs focus on enhancing the efficiency and responsiveness of fan coupling devices.
Latest Patents
Yamada's latest patents include a highly reactive fluid fan coupling device and a temperature sensitive fluid type fan coupling apparatus. The highly reactive fluid fan coupling device utilizes the non-Newtonian fluid characteristics of oil to achieve an excellent reaction rate of fan rotation using a control signal. This device features a sealed housing supported on a rotary shaft, with a drive disk secured to it. The interior is divided into an oil reservoir chamber and a torque transmission chamber, allowing for effective torque transmission through oil supplied to the torque transmission chamber. The flow path of the oil is controlled by a valve member actuated by an electromagnet, which enhances the device's responsiveness.
The temperature sensitive fluid type fan coupling apparatus is designed to obtain linear characteristics without compromising drag performance. This apparatus also has a sealed case divided into an oil reservoir chamber and a torque transfer chamber. A valve regulates the outflow in accordance with external ambient temperature, while the transfer of torque is controlled by adjusting the effective contact surface of the oil with the driving disk. An idle oil reservoir chamber is formed within the driving disk, further optimizing its functionality.
