Abstract
A solenoid valve is disclosed for the closing of a seal seat which is located in the lift direction of the magnet armature and the sealing element, especially a regeneration valve for a fuel tank ventilation arrangement for motor vehicles. The magnet armature of the solenoid valve is biased against the seal seat by an elastic force generated by a pair of flat springs mounted in the valve housing for supporting the magnet armature and the sealing element connected therewith. Canting of the magnet armature and wear of the support of the magnet armature are substantially prevented and a good long term operational reliability is achieved.
Description
SOLENOID VALVE
The invention relates to a solenoid valve for the closing of a seal seat which is located in the lift direction of the magnet armature and the sealing element.
In particular, the invention relates to a regeneration valve for a fuel tank ventilation arrangement in motor vehicles.
BACKGROUND ART
The use of electromagnetic metering valves is generally known. The throughput of such valves in both directions can be controlled by variation of the pulsa~pause-ratio of the electrical actuation. The magnet armature which during operation carries out an oscillating movement, is herefore pressed at variable time intervals against a seal seat, or lifted from the seal seat depending on the desired amount of input. At the end face, the magnet armature is provided with a seal seat elastomer. These valves generally have to be resistant to aggressive media and have to maintain their metering precision over a large temperature range. They Furthermore should not be noticeable acoustically and able to be manufactured at low cost. Solenoid valves are mostly used for this purpose which permit a fast movement of the sealing element and have a control frequency which is at least 10 Hz. The mounting of the magnet armature is a special problem of these solenoid valves, which armature during operation achieves very high cycle rates but still should have a very high life expectancy.
DE 42 29 110 C 1 shows a regeneration valve in which the sealing element is operated by an electrically driven magnet coil. Such regeneration valves have proven reliable in practice.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an improved supporting of the magnet armature in order to ensure a characteristic line band with tight tolerances even after long times of operation of the valve. Furthermore, it is an object to reduce large throughput of fuel vapors, which leads to an improved magnetic force-distance characteristic curve.
Moreover, it is an object to improve the miero-metering behavior of the valve.
This is achieved in a solenoid valve in accordance with the invention by supporting the magnet armature by two flat springs joined to the valve housing. This provides a friction free supporting of the magnet armature. Friction forces which are present with conventional guiding and supporting arrangements for the magnet armature in an armature sleeve or in hollow plates, are prevented with the construction of the invention. This results in an especially good force-distance characteristic curve for the magnet force to be used. Canting of the magnet armature is safely prevented by positioning of the flat springs to both sides of the magnet armature. Wear of the support of the magnet armature is prevented and a good long-term behavior over the whole service life is achieved.
In a preferred embodiment, the flat springs are constructed as meander springs.
For weight reduction, the magnet armature, is preferably of cylindrical shape.
The sealing element is positioned at that end of the magnet armature which is directed towards the seal seat. It thereby covers the inner bore of the armature.
A high throughput of fuel vapor is made possible by shaping the magnet armature to concentrically surround the whole core with its upper edge. A larger feed through can thereby be realized. In an especially preferred embodiment of the solenoid valve of the invention, the magnet armature is coaxially surrounded by the pole plate. The pole plate is connected with the housing of the solenoid valve and the meander springs are preferably joined to both sides thereof. For that, the pole plate is provided on both sides with space protrusions to which the meander springs are mounted. The meander springs are pressed or welded onto the space protrusions. For reasons of manufacturing technology and to facilitate mounting of the metal guide plate to the valve housing, the metal guide plate can be constructed to be reverse-symmetrical with respect to the meander springs, which means that the metal guide plate can be connected in either orientation with the meander springs and the valve housing, irrespective with which side is directed into the housing.
The sealing element is preferably made of a metallic supporting body provided with perforations and an elastomeric sealing cover which is positively and/or non-positively connected with the supporting body. This allows for a very secure connection between the sealing cover and the supporting body. Furthermore, the supporting body facilitates the connection of the sealing element with the magnet armature.
The magnet armature is preferably provided at its edge facing the seal seat with a circumferential indent into which the supporting body is pressed.
The embodiment in accordance with the invention of a magnet armature with sealing element and flat springs can be especially advantageously used in a regeneration valve with a valve housing and a central Laval nozzle, the mouth of which forms the seal seat.
BRIEF DESCRIPTION OF THE DRAWINGS
Preferred embodiments of the invention will now be further described by way of example only and with reference to the attached drawings, wherein Figure 1 is a longitudinal section through a preferred embodiment of a solenaid valve in accordance with the invention;
Figure 2 is an end view of the magnet armature with flat spring and pole plate of the valve shown in Figure 1;
Figure 3 is a side elevation of the magnet armature, the flat springs and the pole plate of the valve shown in Figure 1; and Figure 4 is a cross-section through the magnet armature, the flat springs and the pole plate taken along line C-C' in Figure 2.
Figure 1 illustrates in longitudinal section a solenoid valve which allows a high activation frequency. The solenoid valve 1 includes an upper housing portion 2 and a lower housing portion 3. An electromagnet 4 with a pole core 12 is inserted in the upper portion 2. The pole core 12 cooperates with the magnet armature 5 which is provided with a sealing element 6. The sealing element ti is forced by a bring 7, position and centrally in the electric magnet onto the seal seat 8 which is located in the lower housing portion 3. However, an embodiment without spring 7 in which only the flat springs !~ and force the seal element 6 onto the seal seat 8 is also possible and advantageous for some applications. The magnet armature 5 is held by the flat springs 9 and 10, which are constructed as meander springs. A pole plate 13 is mounted to the magnetic yoke 11 of the electromagnet 4, which pole plate simultaneously functions as a mount for the magnet armature 5. However, contact between magnet armature S and the pole plate 13 is not provided. The pole plate 13 is provided on its upper and lower surfaces with space protrusions 14 and I S to which the meander springs 9 and 10 are fastened. The two housing portions, upper portion 2 and lower portion 3 are connected with one another.
The Laval nozzle 1 b is positioned centrally in the lower housing portion 3 and the intake of the nozzle forms the seal seat 8. The medium flowing through the valve enters into the annular chamber 17 of the lower valve potion 3 and exits through the Laval nozzle 16.
Figure 2 shows an end view of the pole plate l3 with the meander spring 10 mounted thereto and the magnet armature 5 held by the meander spring 10. The underside of the sealing element 6 is visible. The pole plate 13 is provided with two opposite tabs 19 and 20 by which it is mounted to the magnetic yoke 11.
Openings 2l are provided in the pole plate 13 for insertion of complementary pins 21 on the magnetic yoke 11. The meander spring 10 is provided with three spring legs 22. It is at its inner edge 23 pressed or welded onto the magnetic armature 5. The meander spring 10 is also connected with the protrusions 14 at the point of connection 24 for the spring legs 22.
The protrusions 1 S located below the pole plate 13 are shown in broken lines.
The meander spring 9 located below the pole plate 13 is pressed onto these protrusions 15.
The protrusions 15 are revers-symmetrical to the protrusions 14, which means the pole plate 13 can be used with either side facing up.
Figure 3 illustrates in side view the pole plate 13 with the meander springs 9 and and the magnet armature 5 with the sealing element 6. Three space protrusions 14 are visible and two oppositely positioned space protrusions 15.
Figure 4 shows a cross-section through Figure 2 taken along line C-C. The magnet armature 5 is held in relation to the pole plate 13 by the meander springs 9 and 10. The pole plate 13 is for this purpose provided with the space protrusions 14 and 15.
As is apparent from the lower portion of the Figure, the protrusions 14 and 15 were manufactured by stamping parts of the pole plate 13. The sealing element 6 is inserted into the cylindrical magnet arnlature ~. The sealing element 6 consists of the metallic supporting body 30, which is provided with a perforation, the elastomeric sealing layer 31 on both sides of the supporting body 30, and the stop 32. The spring 7 is placed onto the central pin 18 on the sealing element 6. During the vulcanization process for application of the sealing layer 31 and the stop 32, the elastomer flows through the perforation in the supporting body 13 so that a non-positive connection is achieved between the supporting body 30 and the elastomeric seal seat 31 or the stop 32. However, a positive connection between the supporting body 30 and the sealing layer 31 achieved, for example, by vulcanizing the elastomeric directly onto the supporting body, is also possible. The circumferential edge 33 of the supporting body 30 is inserted into a circular groove 34 in the magnet armature 5 for connection of the sealing element 6 with the magnet armature 5. The end 35 of the magnet armature 5 which is directed towards the pole core 12 is conically shaped on its inner surface 36 and suwounds the lower edge of the pole core 12 which is of complementary shape. This construction and arrangement of the magnet armature 5 and the pole core 12 provides a high flow through in the open position of the valve 1.
The invention relates to a solenoid valve for the closing of a seal seat which is located in the lift direction of the magnet armature and the sealing element.
In particular, the invention relates to a regeneration valve for a fuel tank ventilation arrangement in motor vehicles.
