  • Publication number: 20190051439
    Abstract: The invention relates to a solenoid valve having an actuator body (17), in which a magnet coil (15) that interacts with a magnet core (16) is arranged and which interacts with an armature (14) that can be moved relative to the magnet core between two end positions and is acted upon by the spring force of an armature spring (13) in a movement direction pointing away from the magnet core (16). The magnet core and the armature have stop surfaces (18a, 18b) which are interrupted by a recess (29) that receives the armature spring. According to the invention, a solenoid valve is provided which is improved with respect to the function of the solenoid valve and the stress on the stop surfaces (18a, 18b) that causes wear. This is achieved in that the magnet core (16) and/or the armature (14) have/has a design (30, 31), in particular a spherical or toroidal design, which reduces the stress on the edges in the region of the stop surfaces (18a, 18b).
