Title: Ryutaro Fukumoto: Innovator in Starter Apparatus Technology
Introduction
Ryutaro Fukumoto is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of engineering, particularly in the development of starter apparatuses for internal combustion engines. With a total of 6 patents to his name, Fukumoto's innovations have the potential to enhance the efficiency and functionality of engine starters.
Latest Patents
One of Fukumoto's latest patents is a spiral spring type starter apparatus for an internal combustion engine. This innovative apparatus features a power accumulator mechanism that includes a spiral spring, which is fixed at one end to a starter shaft and at the other end to a power accumulator box. The design incorporates a ratchet device on both the starter shaft side and the power accumulator box side, allowing for the maintenance of a power accumulated condition in the spiral spring. Additionally, it enables power to be input to the power accumulator box and output from the starter shaft. The apparatus also includes a centrifugal type ratchet mechanism positioned between the starter shaft and the crank shaft of the engine. A motor, powered by a generator through a control circuit after the engine starts, drives the system, while a power transmission device transmits output power from the motor to the power accumulator box. This design allows for a reduction in the size of the motor and battery, and simplifies the assembly of the starter.
