Latest Patents

Okamoto's latest patents include innovative designs for fuel injection pumps. The first patent describes a fuel injection pump that features a control rack arranged in a rack chamber between a pump head and a pump housing. This design allows for the adjustment of fuel injection amounts. Additionally, it includes a transmission shaft that is rotatably supported by a transmission shaft hole in the pump housing. A lubricating oil passage is also formed in the pump housing to pressure-feed lubricating oil between the transmission shaft and the transmission shaft hole. The transmission shaft contains an oil passage that allows lubricating oil to flow through, with openings strategically placed for optimal performance.

The second patent focuses on a fuel injection pump equipped with an electromagnetic spill valve. This valve is designed to adjust the fuel injection amount by releasing pressurized fuel through the opening and closing of a spill valve body. An Engine Control Unit (ECU) is integrated to form a current waveform for the drive current of the electromagnetic spill valve. The ECU detects the valve-close timing during the warm state and applies an optimum current waveform, while during the cold state, it uses a pre-set current waveform.
