Latest Patents
One of Ishihara's latest inventions is a malfunction diagnosis device for a leakage diagnosis device. This device is designed for an evaporative fuel treatment system and includes a first vent valve, a second vent valve, and a pump. The first vent valve blocks a main atmospheric passage connecting a canister with an atmospheric opening, while the second vent valve blocks a bypass passage. The pump is strategically placed to pressurize or depressurize the second atmospheric passage. The malfunction diagnosis device utilizes outputs from a pressure sensor, a current value of the pump, or an air-fuel ratio sensor to perform diagnostics.
Another notable invention is a vane pump, which consists of a casing, rotor, vanes, motor, and a fixed member. The casing defines a pump chamber, and the rotor is designed to eccentrically rotate within it. The vanes move along the inner surface of the casing, and the motor rotates the rotor. The design includes a flange that is fixed to a member with a different linear expansion coefficient than the casing, enhancing the pump's performance.
