Latest Patents

One of Kondoh's notable inventions is the variable discharge high pressure pump, designed for pumping fuel into the 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 plunger's end face and the inner peripheral surface of the cylinder bore. A solenoid valve plays a crucial role in its operation; when deenergized, the valve member moves into an open position, allowing fuel to enter the pumping chamber. Conversely, when the solenoid valve is energized, the valve member returns to a closed position, with the fuel pressure in the pumping chamber pressing the valve member against its seat. Notably, the plunger is constructed with a simple cylindrical structure, free from any lead, ensuring reliable performance.
