摘要： An electromagnetic valve includes: a solenoid having a tubular guide part having the same center as a central axis extending in an axial direction; a movable element disposed inside the guide part and movable in the axial direction; a cover housing the solenoid and the movable element, defining a hole portion, and made of a magnetic material; a pin located at the hole portion and movable along with movement of the movable element; and a valve section provided outside the cover and opened/closed along with movement of the movable element and the pin. The solenoid has a core that surrounds an outer side of the movable element in the radial direction, and a coil that magnetizes the core. The core has an annular ring part surrounding the outer side of the movable element, and tooth parts protruding radially outward from the ring part on which the coil is mounted.

摘要： An electromagnetic valve includes a pressing member fixed farther towards an electromagnetic movable section side than a valve chamber in a nozzle. The pressing member is fixed to a plunger farther towards the side where the plunger is pressed by the pressing member than a position where the pressing member is fixed to the nozzle. Thus, a magnetic circuit defined by magnetic flux that is generated from a magnet is prevented from being located at a portion not related to an attractive force between a core and the plunger such that it is possible to effectively utilize the magnetic flux as an attractive force between the core and the plunger.

摘要： A self-holding electromagnetic valve includes: a solenoid having a tubular guide part having the same center as a central axis extending in an axial direction; a axially movable element located radially inside the guide part; a cover housing the solenoid and the movable element, having a hole portion, and made of a magnetic material; a pin located at the hole portion and movable along with movement of the movable element; and a valve section provided outside the cover and opened/closed along with movement of the movable element and the pin. The solenoid has a cylindrical part with an inner circumferential surface that receives the guide part, tooth parts that extend radially outward from the cylindrical part and are made of a magnetic material, bobbin parts provided each tooth part, and coils wound around the bobbin parts.
