Title: Tamiyoshi Ohashi: Innovator in Fuel Reservoir Technology
Introduction
Tamiyoshi Ohashi is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of automotive technology, particularly in fuel reservoir systems. With a total of 5 patents to his name, his work has had a considerable impact on fuel management in vehicles.
Latest Patents
Ohashi's latest innovations include the "Fuel Reservoir Apparatus" and the "Fuel Vapor Processing Device." The Fuel Reservoir Apparatus is designed to maintain and control pressure within a fuel tank at a low level during engine operation, while also preventing excessive refueling. This apparatus consists of several components, including a fuel tank, canister, fuel vapor passage, positive pressure valve, solenoid valve, and closure valve. The fuel tank stores liquid fuel for the engine, and the canister adsorbs fuel vapor. The positive pressure valve controls the pressure within the fuel tank using a spring force, while the solenoid valve allows fuel vapor to flow towards the canister during engine operation. The closure valve ensures that the fuel vapor passage is closed when fuel is supplied to the tank.
The Fuel Vapor Processing Device facilitates the transfer of fuel vapor from the fuel tank to the canister when fuel is added through the fill pipe or when the tank pressure rises. It employs diaphragm valves that respond to pressure changes, ensuring efficient movement of fuel vapor to the canister.
