Latest Patents
One of Sakamoto's latest inventions is a failure diagnosis device for a fuel pump. This innovative device is designed to determine whether a fuel pump, which supplies fuel to an engine, has failed. The pump consists of multiple pressure chambers that discharge fuel based on the rotation of an input shaft connected to the engine. The device sets the supply capacity of the fuel pump to a value lower than the maximum fuel supply required by the engine when one of the pressure chambers fails. It includes a mechanism that assesses whether the engine's fuel supply needs are being met, allowing for accurate diagnosis of fuel pump failure. Additionally, the device can detect the power output of the engine for each cylinder individually, enabling precise identification of fuel supply insufficiencies.
Another significant patent by Sakamoto involves a fuel pump that pressurizes fuel through the expansion and contraction of a pump chamber within a casing. This design features a first seal member that prevents fuel from escaping the casing and a second seal member that works in conjunction with the first. To further enhance reliability, a drain conduit is included to manage any fuel leakage between the two seal members.
