Abstract: The invention relates to a method for producing a rotary slide valve for regulating a flow of a fluid, comprising a rotary slide (02) which is rotatably mounted about a rotational axis (R) in a valve housing. The method has the steps of: producing the rotary slide (02) in an injection molding method, in particular in a plastic injection molding method; producing at least one circumferential or casing section (04) of the valve housing (03) in an injection molding method, in particular in a plastic injection molding method; and installing the rotary slide valve or a precursor thereof.

Abstract: A proportional spool valve (1) for adjusting a displaced volume of a displacement pump, in particular of an oil pump in a motor vehicle, the proportional spool valve (1) includes a valve housing (2) and a valve spool (3) which is mounted in the valve housing (2) and displaceable along a displacement axis (V) and which can be displaced against the spring force of a valve spring (6) axially supported on a spring holder (7) which is fixed relative to the valve housing (2) by energizing an electrical coil assembly (10), characterized in that wherein both the preferably single-piece spring holder (7) and the valve housing (2) are made of plastic and that the spring holder (7) is welded to the valve housing (2), an integral welded connection (9) being formed.

Abstract: The invention relates to a method for producing a valve housing (1) having a plastic body (2) with at least one fluid opening (5) which is protected by means of a filter (6) against the inlet of dirt.

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.

Abstract: An electromagnetic actuator includes an armature (18) movable axially relative to a stationary core (14) as a reaction to energizing of a stationary coil (12) in an actuator housing (10). The armature (18) is gripped by an axially extended slide (20) guided in a core passage (50) of the core such that a movement of the armature in the direction of the core entrains the slide. An end section (26) of the slide, axially opposite the armature, cooperates with an adjusting partner, the slide having a long rod section (34) and a disk-type end section (30) with a widened diameter on the rod section, on the end in the direction of the armature (18), 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.
