- a magnet coil is provided, which generates a magnetic field during electrical energization, the lines of force via an axial air gap in the magnet armature axially on and radially emerge through the armature jacket surface in the direction of the valve housing.
- a non-ferromagnetic spacer ring which must be sealed between the valve body and the pole core, so that the hydraulic pressure does not escape via the magnetic coil into the atmosphere.
- the magnetic drive can only be inserted into the tubular valve housing when first the spacer ring and the pole core have been used as separate parts in the valve housing and pressed together liquid-tight.

- a magnet coil 1 is advantageously integrated in the cartridge body 5.
- Radially inward as well as radially outward to the magnetic coil 1 is the magnetic flux conducting part of the cartridge body 5, wherein the ferromagnetic conductive part of the cartridge body 5 is interrupted below the magnetic coil 1 by a magnetic flux non-conductive portion 17 to avoid a magnetic short circuit.
- Axiallufttspalt 2 Between the magnetically conductive part and the magnetically non-conductive portion 17 of the cartridge body 5 and the armature 3 is Axiallufttspalt 2, whereby at current-carrying magnetic coil 1 via this Axialluftspalt 2 of the armature 3 an axial entry and exit of magnetic field lines 4 in the manner shown is exposed .
- one of the magnetic coil 1 facing end face of the armature 3 covers a the outer periphery of the magnetic coil 1 enclosing, the magnetic flux conducting part of the cartridge body 5, which is why the outer diameter of the magnet armature 3 is chosen to be larger than the outer diameter of the magnet coil 1.
- the magnet coil 1 is advantageously inserted from above into a matched to the size of the magnetic coil 1 annular groove 6 of the cartridge body 5, both sides of the magnetically conductive part of the cartridge body. 5 is limited.
- the magnetic coil 1 is covered above the annular groove 6 by a magnetic closing disc 22 which rests flat on the magnetically conductive part of the cartridge body 5 for closing the magnetic circuit.
- the invention is thus based on the idea of integrally forming a part conducting the magnetic flux as well as a section 17 which does not conduct the magnetic flux or only slightly, within the cartridge body 5 and integrating the magnetic coil 1 in the cartridge body 5 in order to achieve a compact, leak-free as possible Get assembly for the magnetic drive, which can be produced as easily as possible in mass production.
- the bottom of the cartridge body 5 is provided in the region of the cross-sectional weakening in a simple manner with at least one weld seam 18 extending concentrically or spirally along the bottom.
- an austenitic annular disc 19 is arranged on the section 17, which is advantageously held by the weld 18 at the bottom of the cartridge body 5.
- the magnetic flux is attenuated in section 17 so far that the electromagnetic field actuation of the magnet armature 3 shown magnetic field line is ensured.
- the cartridge body 5 forms with the magnetic coil 3 and the non-magnetic annular disc 19 is an independently manageable assembly, with a non-magnetic housing pot 7 is connected fluid-tight, in which the armature 3 is arranged axially movable with the valve closing member 14.
- the armature 3 is designed as a plate anchor in order to achieve the lowest possible valve height with the best use of magnetic force can.
- To reduce the hydraulic resistance of the armature 3 is provided with a plurality of distributed over the armature surface symmetrically to the valve longitudinal axis through holes 13 and / or if necessary, also on the outer circumference with symmetrically distributed recesses.
- the armature 3 and the through holes 13 and possibly also the recesses are made particularly efficient by punching the magnet armature 3.
- the magnetic flux conducting part of the cartridge body 5 consists in the two embodiments of a preferably produced by cold striking or extrusion or possibly also by machining of free cutting steel cylinder part, which is known per se from the prior art individual components, consisting of one in the magnetic coil 1 inserted pole core and the outer circumference of the magnetic coil 1 enclosing yoke ring, now united as a homogeneous unit extremely appropriate.
- the cartridge body 5 is inserted with the attached housing pot 7 in the valve receiving bore 16 of a plurality of pressure medium channels 9, 10 having housing 11 liquid-tight.
- the cartridge body 5 is made of a material harder with respect to the material of the housing 11 having a step on the outer periphery with a recess 12 into which the cartridge body 5 during the pressing of the cartridge body 16 softer material of the housing 11 is displaced.
- the magnetic field non-conductive housing pot 7 consists of a particularly cost-effective and precisely manufactured by deep-drawing sleeve part, the sleeve edge is attached to the magnetic flux conducting portion of the cartridge body 5 pressure medium-tight, preferably by means of a welded connection.
- the bottom of the pot is provided with an opening which is bounded by a valve seat 8, which is preferably produced by the execution of the thin-walled sleeve part as austenitic sheet metal part in the embossing process.
- embossing opening 15 is located below the magnet armature 3 in the lateral surface of the housing pot 7 in order to connect the horizontally extending in block-shaped housing 11 pressure fluid channel 9 with a arranged below the valve seat 8 in the housing 11 pressure medium channel 10 can.
- a plate spring 20 is arranged, which keeps the armature 3 to the axial air gap 2 from the magnetic part of the cartridge body 5 in the electrically non-energized state of the magnetic coil 1.
- the use of a plate spring 20 favors a particularly low valve height.
- FIG. 2 shows the electromagnetic valve, which is closed in the basic position and has an annular disk 19 which is modified with respect to FIG. 1 and which has the contour of one between the cartridge body 5 and the disk-shaped one Magnet armature 3 has a clamping plate spring whose inner circumference is connected via the weld 18 to the bottom of the cartridge body 5, so that the plate spring rests with its outer periphery of the front side of the disc-shaped armature 3. Due to the design of the annular disc 19 as a plate spring results in a further reduction of the manufacturing effort by the known from Figure 1 separate disc spring 20 can be omitted if desired or required.
- the electromagnetic valves presented are preferably used in a slip-controlled vehicle brake system for which the block-shaped housing 11 shown only in sections has a plurality of valve receiving bores in one or more rows for receiving the illustrated normally closed solenoid valves in a surface of the housing 11 without any protrusion are admitted.
- the block-shaped housing 11 is particularly low due to the low height of the illustrated solenoid valves.
- the illustrated solenoid valves fulfill the function of selectively influencing the brake pressure and the brake pressure reduction in the wheel brakes in the slip control case by means of suitable control electronics, which preferably abut flatly and thus extremely compactly on the upper side of the electromagnetic valves on the housing 11.
- the proposed features according to the invention result in a particularly short electrical Solenoid valve in various embodiments with respect to the previously known valves approximately twice as large magnetic force.
- the inventively proposed solenoid valves can be completely submerged in the housing 11, which is ensured by the complete integration of the solenoid 1 in the cartridge body 5 and due to the complete integration of the valve housing in the channel-guiding housing 11 excellent heat dissipation for the magnetic drive.
- the complete integration of the solenoid valves in the block-shaped housing 11 also facilitates the arrangement of a control electronics required for the activation of the solenoid valves, which is preferably arranged directly on the surface of the housing 11, from which the contacts 21 of the magnetic coil 1 protrude. This results in a good heat dissipation for the control electronics, since the housing 11 is preferably made of a light metal alloy and acts as a heat sink.
