Abstract
An electromagnetic valve device including armature means (12, 14), which are movable along an axial direction for actuating a valve gate assembly group (28) in reaction to energizing stationary spool means (16), and which are accommodated in an actuator housing (17, 19, 20, 22) preferably as a component unit and/or module in conjunction with the spool means and stationary core means and take up an inserted and/or retracted armature position (FIG. 1) in an unenergized state of the spool means, said valve gate assembly group (28), which is guided in a valve housing (26), being realized at one axial end for a contacting interaction, which cannot endure tensile load, with the armature means (14) and being realized such that a fluid path from a first fluid port (P) of the valve housing to a second fluid port (A) of the valve housing can be opened or blocked depending on an axial position of the valve gate assembly group, said valve housing (26) including at least one axial fluid-conducting channel section (50) on the interior so as to interact with the valve gate assembly group (28) guided therein, in particular at the axial end side opposite to the armature means, said channel section …
