Electromagnetic actuating unit for a hydraulic directional control valve and method for the assembly thereof
An electromagnetic actuating unit for a hydraulic directional control valve and a method for the assembly thereof. The actuating unit has a coil for generating a magnetic field, a yoke unit with a yoke and a yoke plate, and a pole core unit with a pole core and a housing for conducting a magnetic flux, and an armature unit which is arranged in the magnetic field of the coil and has an armature and a pressure pin as an actuator. The armature unit can be displaced in the direction of the longitudinal axis thereof in a first bearing point in the yoke unit and in a second bearing point in the pole core unit. At least one of the hearing points can be displaced in the radial direction during assembly of the actuating unit and can be fixed after a coaxial orientation of both bearing points.
