Title: Hiroaki Toyoda: Innovator in Water Pump Technology
Introduction
Hiroaki Toyoda is a notable inventor based in Anjo, Japan. He has made significant contributions to the field of water pump technology, holding a total of 3 patents. His innovative designs focus on improving efficiency and functionality in variable-capacity water pumps.
Latest Patents
One of Toyoda's latest patents is the "Temperature responsive blade shroud-disk for thermostatic water pump." This invention features a variable-capacity water pump that includes a pump impeller fixed to a rotatable shaft. It is designed to forcibly feed cooling water from a cooling water passage. The system incorporates a mechanical seal behind the pump impeller and a temperature sensor mounted on the rotatable shaft. This sensor detects the temperature of the cooling water and adjusts the operation of the pump impeller accordingly. The result is a water pump that can supply the necessary quantity of cooling water efficiently, without unwanted power loss.
Another significant patent is the "Variable contact centrifugally operated seal mechanism." This mechanism includes a rotatable shaft and a seal body with a wall member. The seal member has a cylindrical portion secured onto the rotatable shaft and a tongue portion that resiliently contacts the seal wall. The continuous resilient contact force changes in response to the rotational speed of the shaft, enhancing the sealing efficiency.
