ABSTRACT:
An electromagnetic actuating device comprising an armature unit which can be moved along a longitudinal axis relative to a stationary core by passing a current through a coil device, said armature unit being designed to form or define a fluid flow channel, wherein the armature unit has at one end an axially elongate cylindrical section, to which an annular groove-shaped section of reduced outer diameter is connected in the direction of the longitudinal axis, wherein the fluid flow channel extends into the annular groove-shaped section, wherein the fluid flow channel runs through the elongate cylindrical section in the manner of a through-channel, in particular a through-bore, running obliquely with respect to the longitudinal axis, so that a first opening at the end side and/or an opposite second opening of the through-channel are provided outside the cylindrical outer wall of the elongate section.
