Latest Patents
One of his latest patents is for an EGR valve that includes a seal ring. The body of the seal ring is in an annular shape and features an abutment joint at a specific location in the circumferential direction. The opposite ends of the body forming the abutment joint include an overlapping part where one end and the other end of the body overlap each other. This overlapping part consists of a step cut joint that creates an overlap in the radial direction and a lap joint that forms an overlap in the plate thickness direction. The facing faces in the lap joint are planes extending from an inner peripheral circular arc of the seal ring to an outer peripheral circular arc of the seal ring. Another notable patent is for a valve device that includes a housing, a shaft, a butterfly valve, and a sealing member. The butterfly valve, which has a disk shape, defines a groove on its outer circumferential surface. It is fixed to the shaft and housed in a passage within the housing to selectively open and close the passage. The sealing member, shaped annularly, fits into the groove, and its outer circumferential surface has an arc surface that matches the diameter of the passage. This arc surface contacts the inner wall of the passage when it is closed.
