Abstract

The solenoid valve has a valve housing which accommodates a valve seat in a housing opening, a push rod shaped valve closing member that can be berthed at the valve seat and allows pressure media channels leading to the valve seat to be connected or separated. A magnet armature is movable axially in the valve housing to accommodate the valve closing member, which is supported by a linkage on the armature in movable fashion. The valve closing member (1) forms a subassembly group with the magnet armature that can be manipulated independently.

Description

The invention relates to an electromagnetic valve, in particular for slip-controlled motor vehicle brake systems after Preamble of claim 1.

DE 20 52 307 A1 is already in the basic position closed solenoid valve became known with a valve housing which in a housing opening Receives valve seat against which a valve closing member rests. The valve closing member is articulated on a magnetic armature stored and in the area of the valve seat by a cone centered. Furthermore, are located above the Valve seat body guide sections for receiving the Valve closing member.

The object of the present invention is a To manufacture the electromagnetic valve of the specified type inexpensive with simple, reliable means can be manufactured.

This object is inventively for Solenoid valve of the aforementioned type with the characterizing features of claim 1 solved.

Further features, advantages and design options of the invention will become apparent in the following from the description of several exemplary embodiments with reference to FIGS. 1 to 8.

Fig. 1 shows a for all subsequent embodiments (Fig. 2 to 8) generally valid, representative overall view in greatly enlarged representation of a closed basic position solenoid valve, which is used in particular for slip-controlled automotive vehicle brake systems. In the present exemplary embodiment, the valve housing 14 of the solenoid valve designed as a pressure control valve is manufactured in a cartridge design and is pressed into a valve holder body 20 that is softer relative to it, by means of self-caulking of the harder valve housing material, which is preferably made of steel. The valve housing 14 receives in its housing opening 21 a valve seat body 12 against which, under the action of a compression spring 22, a valve closing member 1 articulated on a magnet armature 6 bears. The magnet armature 6 is axially movable along the wall of the housing opening 21 . For the electromagnetic actuation of the magnet armature 6 , a valve coil 15 is arranged on the valve housing 14 , which is centered on a magnetic closure disk 19 arranged between the valve coil 15 and the valve housing 14 . The valve housing 14 is closed on its sleeve-shaped shaft section by means of a pressed-in and welded sealing plug 16 on the side facing away from the valve seat body 12 . The sealing plug 16 takes over the function of a magnetic core in the present exemplary embodiment. The valve coil 15 is surrounded by a yoke ring 18 which contacts the magnetic closure disk 19 at the end of its outer lateral surface, while the other end of the inner side of the jacket extends as far as the sealing plug 16 . The valve spool 15 is centered over the sleeve-shaped shaft section of the valve housing 14 . This is promoted by means of a bevelled transition on the valve housing 14 in the direction of the sleeve-shaped stem section.

With regard to the hydraulic part of the pressure control valve, it should not go unmentioned that the proposed stepped sleeve contour of the valve housing 14 not only creates the best conditions for generating the necessary holding and sealing force within the valve receiving body 20 , but also a simple arrangement of filter elements 25 , 26 comes about, which are designed in the present exemplary embodiment as plate and ring filters and which reliably protect the pressure medium channels 11 which open into the valve housing 14 in the horizontal and vertical directions from contamination of the valve interior parts. In the present exemplary embodiment, the valve seat 12 is pressed as a separate, rotationally symmetrical component from the direction of the closure plug 16 closing the housing opening 21 into the valve housing 14 and / or caulked. Manufacturing and fastening alternatives are conceivable for this, but are not regarded as an essential feature of the solution of the invention.

Rather, in the following parts of the description of the invention, the astonishingly simple articulated positioning of the valve closing member 1 on the armature 6 will be discussed, which will now be described with reference to the individual design details shown in FIGS. 1 to 8. Basically, it can be assumed that the basic valve structure for all further exemplary embodiments according to FIGS . 2 to 8 is identical according to the description part of FIG. 1.

Thus show in detail:
The Fig. 1 as well as all subsequent embodiments (FIGS. 2-8) has a particularly simple, functionally reliable, independently operable subassembly which is formed from articulatedly held on the magnet armature 6 valve closure member 1.

From the further details according to FIG. 1 it can be seen that the valve closing member 1 is guided in a sleeve-shaped extension 3 and this has a collar 8 which has a radial play relative to the sleeve-shaped extension 3 of the magnet armature 6 . The magnet armature 6 has a constriction 5 in the vicinity of the joint 7 , which is preferably designed as a spherical head, which, according to the illustration, is implemented by radial caulking on the extension 3 .

In an alternative embodiment of the above-described details, it is also proposed according to FIG. 2 that a compression spring 9 is arranged between the joint 7 and the constriction 5 of the extension 3 , which freely releases the joint 7 attached to the valve closing member 1 against a so-called joint socket in the magnet armature 6 presses. Also in the embodiment according to FIG. 2, the valve closing member 1 is guided in a sleeve-shaped extension 3 of the magnet armature 6 and is provided with a collar 8 which acts as a stop in the extension and which has radial play for aligning the tappet-shaped valve closing member 1 with respect to the valve seat body 12 .

In the representation of the solenoid valve of FIG. 3 in the sleeve-shaped extension 3 a bushing 10 is pressed, can be in the tappet portion of the valve closure member 1 with play radially align. Furthermore, there is a compression spring 9 between the joint 7 and the bush 10 , which presses the spherical joint 7 into the joint socket of the magnet armature 6 without play.

A further variant of FIG. 3 is shown in FIG. 4, according to which, in a departure from the illustration according to FIG. 3, the socket 10 extends to the spherical joint 7 .

Notwithstanding Fig. 4 5 shows an arrangement of the valve closing element 1 is shown in Fig. Proposed in the armature 6, which is designed so that between the bush 10 and the pivot 7 a rubber disc can be clamped. 13

As can be seen from the previous exemplary embodiments according to FIGS. 1 to 5, the spherical joint 7 is in each case attached to a tappet-shaped valve closing member 1 .

Deviating now to FIG. 6 shows an embodiment of the prior art of FIG. 1 solenoid valve in which the spherical joint 7 is attached via a short cylindrical section on the magnet armature 6. The sleeve-shaped joint head attached to the valve closing member 1 engages around the ball of the joint 7 in such a way that the valve closing member 1 is held on the ball section of the joint 7 by means of a radial indentation in the open region of the joint head. Between the magnet armature 6 and the articulated head of the valve closing element 1 there is an elastic element 17 in the form of a rubber disc at the level of the cylinder section, which element contributes to the alignment of the valve closing element 1 with respect to the valve seat body 12 .

Fig. 7 shows an approximation of the valve embodiment according to FIG. 1, the valve closing member 1 in a sleeve-shaped projection 3 of the armature 6 made a collar 8 is provided on the plunger portion of the valve closing element 1, in turn, provided with a radial play relative to the sleeve-shaped extension 3 is. As already known, the joint 7 designed as a ball head is secured with a constriction 5 in the region of the extension 3 against falling out of the magnet armature 6 . This constriction 5 can be designed, for example, as radial caulking arranged over the circumference at several locations. In order to ensure that the valve closing member 1 presses in the closed position against the valve seat body 12 and closes it securely, a compression spring 23 is effective between the magnet armature 6 and the joint 7 in the direction of the valve closing member 1 , which is located in an elongated stepped bore 2 of the magnet armature 6 located and supported there.

Deviating from the illustration according to FIG. 7, the differences of the embodiment according to FIG. 8 are highlighted below in detail, which are mainly due to the structurally simplified design of the magnet armature 6 , the sealing plug 16 acting as a magnetic core and the tappet-shaped valve closing element 1 from those previously described Assemblies according to Fig. 7 differs. The anchor hole 24 is now designed as a tapered step bore, whereby on the one hand the tapered step 27 enables a uniform, easy-to-produce bearing surface for receiving the spherical joint 7 , to which the anchor hole 24 is connected above the joint 7 for almost completely receiving the compression spring 22 with a constant cross section, while below the joint 7, the tapered step 27 merges into the relatively narrow armature bore 24 , in which the valve closing member 1 is securely guided with small radial play for articulated alignment. As a result, the constriction 5 proposed in FIG. 7 and subsequently to be attached to the magnet armature 6 in terms of production technology can be dispensed with, the plug 16, which acts as a magnetic core, no longer being provided with a bore, due to the now almost completely displaced displacement of the compression spring 22 into the armature bore 24 needs. In order to position the magnet armature 6 with the cone step 27 in the electromagnetically non-energized rest position freely on the joint 7 , there is a spring 4 between the valve housing 14 and the magnet armature 6 in the housing opening 21 , the spring preload force of which is smaller than the force of the compression spring 22 .

All of the design variants described so far provide for a central alignment of the valve closing element 1 with respect to the valve seat body 12 . If desired or required, however, it is also possible to align the valve closing member 1 articulated on the armature 6 according to FIGS. 1-8 eccentrically with respect to the valve seat body 12 . With a valve closing member 1 , which is mounted eccentrically to the longitudinal axis of the valve, the joint 7 of which is fastened relatively stiffly in the magnet armature 6 , ie the joint 7 can only be moved with a correspondingly large torque in the magnet armature 6 , when the valve closing member 1 and the magnet armature 6 are installed formed subassembly a calibration of the valve closing member 1 on the valve seat body 12 possible. For this purpose, the magnet armature 6 is pressed in the direction of the valve seat body 12 with a relatively high force of, for example, 500 to 1000 N. The hereby occurring at the valve closure member 1 Transverse force acting on the armature 6, causes an application of the armature 6 on the sleeve-shaped portion of the valve housing 14 while maintaining a relatively small air gap. The resulting setting of the magnet armature 6 relative to the valve housing 14 and the valve closing member 1 on the sealing seat is maintained during valve actuation and is intended to prevent the radial forces on the sealing seat that occur on the magnet armature 6 .

Instead of the eccentrically aligned valve closing element 1 , the concentric alignment of the valve closing element 1 mentioned in the introduction in the magnet armature 6 can also be maintained, if desired or required, with a correspondingly large torque on the joint 7 . To calibrate the subassembly consisting of the valve closing member 1 and the magnet armature 6 with respect to the valve sealing seat, this subassembly is inserted into the valve housing 14 without a specific orientation having to be maintained. A so-called calibration stamp is then inserted into the anchor hole 24 . In a first step, the calibration stamp is only partially inserted into the anchor hole 24 . The latter exerts a transverse force on the magnet armature 6 , so that it contacts one side of the valve housing 14 . In a second method step, the magnet armature 6 is pressed with an axial force in the direction of the sealing seat, the magnet armature 6 , however, resting on one side of the valve housing 14 unchanged. The armature 6 forces the hinge 7 mounted on the valve closure member 1 to the sealing seat on the valve seat body. 1 The torque required for centering the valve closing element 1 is brought about by a transverse force which results from the axial force of the calibration plunger and a slope on the sealing seat. The calibration process ends when the final position on the sealing seat is reached.
