Patent number: 6864771Abstract: The electromagnetic valve has an electromagnetic actuator for operating a valve. The electromagnetic actuator has a movable core that reciprocally moves in an axial direction. A stator core has an attracting portion. The attracting portion has a conical portion that is defined by a uniform diameter inner surface and an outwardly inclined outer surface. The outer surface has a smaller diameter at a position closer to an initial position of the plunger. Therefore outer diameter of the conical portion is increased in an attracting direction of the plunger. Moreover, increasing rate of the outer diameter is decreased in the attracting direction. Therefore the outer surface has a greater inclination angle at a position closer to an initial position of the plunger.Type: GrantFiled: May 22, 2002Date of Patent: March 8, 2005Assignee: Denso CorporationInventors: Tadashi Komiyama, Katsuhiro Kuroki, Koji Sakurai, Michio Koshimizu, Kazuto Maeda
