An electromagnetic actuator includes an armature () movable axially relative to a stationary core () as a reaction to energizing of a stationary coil () in an actuator housing (). The armature () is gripped by an axially extended slide () guided in a core passage () of the core such that a movement of the armature in the direction of the core entrains the slide. An end section () of the slide, axially opposite the armature, cooperates with an adjusting partner, the slide having a long rod section () and a disk-type end section () with a widened diameter on the rod section, on the end in the direction of the armature (), the axial extension (W) of the end section determining a minimum distance between the armature and the core in an abutment state of the armature on an end surface and/or front surface of the core, facing the armature.

Electromagnetic actuator device and use of such a device

A proportional spool valve () for adjusting a displaced volume of a displacement pump, in particular of an oil pump in a motor vehicle, the proportional spool valve () includes a valve housing () and a valve spool () which is mounted in the valve housing () and displaceable along a displacement axis (V) and which can be displaced against the spring force of a valve spring () axially supported on a spring holder () which is fixed relative to the valve housing () by energizing an electrical coil assembly (), characterized in that wherein both the preferably single-piece spring holder () and the valve housing () are made of plastic and that the spring holder () is welded to the valve housing (), an integral welded connection () being formed.

Proportional spool valve for adjusting the displaced volume of a displacement pump, assembly method and system

The invention relates to a method for producing a valve housing () having a plastic body () with at least one fluid opening () which is protected by means of a filter () against the inlet of dirt.

Method for producing a valve housing and valve

An electromagnetic valve device including armature means (), which are movable along an axial direction for actuating a valve gate assembly group () in reaction to energizing stationary spool means (), and which are accommodated in an actuator housing () 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.) in an unenergized state of the spool means, said valve gate assembly group (), which is guided in a valve housing (), being realized at one axial end for a contacting interaction, which cannot endure tensile load, with the armature means () 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 () including at least one axial fluid-conducting channel section () on the interior so as to interact with the valve gate assembly group () guided therein, in particular at the axial end side opposite to the armature means, said channel section () being realized such that the valve gate assembly group () blocks the fluid path in the axial position of the valve gate assembly group corresponding to the inserted and/or retracted armature position and said valve gate assembly group () opening the fluid path via the flow-conducting channel section () in an axial position of the valve gate assembly group, which is moved out of the inserted and/or retracted armature position.
