Latest Patents

One of his latest inventions is a variable discharge high pressure pump designed for pumping fuel into a common rail of a common rail type fuel injection system. This innovative pump features a plunger that is reciprocable within a cylinder bore, creating a pumping chamber defined between the end face of the plunger and the inner peripheral surface of the cylinder bore. A solenoid valve is incorporated, which has a valve member that can move into an open position when the solenoid valve is deenergized, allowing fuel to enter the pumping chamber. Conversely, when the solenoid valve is energized, the valve member moves into a closed position, where the fuel pressure in the pumping chamber urges the valve member into engagement with the valve seat. Notably, the plunger is designed with a simple cylindrical structure, free from any lead formed within it.
