Latest Patents
One of Okada's latest patents is a high-performance sealing device designed to withstand excellent pressure resistance. This sealing device operates effectively at a working pressure of 0 to 2 MPa and remains undamaged even when subjected to high-pressure fuel of 5 MPa or higher. The design features a dual seal structure, where a first seal part seals high-pressure fuel, while a second seal part prevents oil leakage from the cam side. The use of a resin ring in the first seal part ensures that abnormal abrasion does not occur, even with fuels that have low lubricity, thereby increasing the seal's durability.
Another significant patent is the plunger seal for a fuel injection pump intended for direct-injection gasoline engines. This plunger seal utilizes a resin material for the fuel seal member, allowing for a compact design while enhancing sealing ability and reducing assembly time. The incorporation of a U-shaped elastic member in the groove of the fuel seal member ensures optimal sealing performance.
