Patent number: 11976618Abstract: A fixed core generates a magnetic attraction force with energization of a coil. A movable core has an attracted surface facing an attracting surface of the fixed core is attracted to the fixed core to cause the valve body to open a nozzle hole. A stopper member abuts against the movable core to restrict movement of the movable core. The movable core has an abutment portion that abuts against the stopper member, and a core body portion in which the attracted surface is formed. The attracting surface and the attracted surface extend annularly around an axis line of the fixed core, are formed so as to be separated from each other in an axis line direction in a state where the abutment portion abuts against the stopper member, and a separation distance from each other increases toward a radially outer side.Type: GrantFiled: July 6, 2021Date of Patent: May 7, 2024Assignee: DENSO CORPORATIONInventors: Shinsuke Yamamoto, Yuki Watanabe, Atsuya Okamoto
