Title: Innovations by Tatsuro Koga in High-Pressure Pump Technology.
Introduction
Tatsuro Koga is an inventor based in Kariya-city, Japan. He has made significant contributions to the field of high-pressure pump technology. Although he currently holds no granted patents, his innovative ideas are reflected in his latest patent applications.
Latest Patent Applications
One of Koga's latest patent applications involves a high-pressure pump design. This design features a discharge valve located in the discharge passage, which is openable to allow fuel flow from a pressurizing chamber to a discharge outlet. This mechanism operates based on the fuel pressure difference between the pressurizing chamber and the discharge outlet. Additionally, a relief is integrated into a relief passage that connects a branching portion and a return portion, enabling controlled fuel flow in response to pressure differences. Another application describes a gas chamber adjacent to a variable volume chamber in a high-pressure pump. This gas chamber includes an inner blocking wall that contacts the fuel and an outer blocking wall, creating a defined space filled with gas.
Conclusion
Tatsuro Koga's innovative approaches to high-pressure pump technology demonstrate his potential as an inventor. His latest patent applications reflect a commitment to advancing engineering solutions in this field.
