Description

Die vorliegende Erfindung betrifft ein Ventil zur Steuerung eines Kühlmittelstroms für einen Heizkörper eines Kraftfahrzeugs nach Anspruch 1 sowie ein System mit zumindest einem solchen Ventil. Zur Beheizung der Fahrgastzelle eines Kraftfahrzeugs wird üblicherweise ein Wärmetauscher, insbesondere ein Heizkörper verwendet, der üblicherweise einen Rippenrohrblock aus Rohren wie beispielsweise Flachrohren aufweist, durch die ein erstes Medium, insbesondere eine wasserhaltige Kühlflüssigkeit, fließt. Benachbart zu den Rohren, insbesondere zu den Flachrohren, sind Rippen wie beispielsweise Wellrippen angeordnet oder mit den Rohren, insbesondere Flachrohren, stoffschlüssig beispielsweise durch Löten, Schweißen, Kleben usw. verbunden. Durch die Rippen, insbesondere die Wellrippen, aber auch durch die Rohre, insbesondere die Flachrohre, wird Wärme an ein an den Flachrohren und/oder den Wellrippen vorbeiströmendes zweites Medium, insbesondere Luft, übertragen. Dabei erwärmt sich die Luft. Die erwärmte Luft wird zur Erwärmung der Fahrgastraumzelle eines Kraftfahrzeugs genutzt.The present invention relates to a valve for controlling a coolant flow for a radiator of a motor vehicle according to claim 1 and a system with at least one such valve. For heating the passenger compartment of a motor vehicle, a heat exchanger, in particular a radiator is usually used, which usually has a finned tube block of tubes such as flat tubes, through which a first medium, in particular a water-containing cooling liquid, flows. Adjacent to the tubes, in particular to the flat tubes, ribs such as corrugated ribs are arranged or connected to the tubes, in particular flat tubes, cohesively, for example, by soldering, welding, gluing, etc. Heat is transferred to a second medium, in particular air, flowing past the flat tubes and / or the corrugated fins through the ribs, in particular the corrugated ribs, but also through the tubes, in particular the flat tubes.

Von dem Verbrennungsmotor strömt zumindest in einem ersten Leitungsabschnitt das vom Verbrennungsmotor erwärmte Kühlmedium zu dem ersten Wärmetauscher, insbesondere dem Heizkörper, durchströmt diesen in den Rohren, insbesondere in den Flachrohren und verlässt den ersten Wärmetauscher, insbesondere den Heizkörper und strömt in einen zweiten Leitungsabschnitt wieder zum Verbrennungsmotor.The first medium, in particular the cooling medium, such as a water-containing cooling liquid or air or another cooling liquid flows at least in sections through an internal combustion engine of a motor vehicle and thereby cools the internal combustion engine of the motor vehicle.

Zumindest ein Teil des ersten Kühlmediums oder das gesamte erste Kühlmedium kann nach dem Verlassen des Verbrennungsmotors durch die Bypassleitung direkt wieder dem Verbrennungsmotor zugeführt werden.Furthermore, an at least third line section is known for bypassing the first heat exchanger, in particular the radiator.

Gemäß der Stellung des zweiten Ventils V2 wird der Heizkörper HK sowie die dem Heizkörper HK vorgeschaltete Pumpe P mit Kühlmittel beströmt oder nicht mit Kühlmittel beströmt. Öffnet das zweite Ventil, so tritt Kühlmedium über die Umwälzpumpe P in den Heizkörper HK, durchströmt diesen und strömt danach in Richtung des Austritts A. Vor dem Austritt fließt der Bypass BP in den zweiten Leitungsabschnitt ZLA. Ein erstes Ventil V1 steuert den Durchfluss an Kühlflüssigkeit oder an Kühlmedium durch den Bypass BP.Medium such as cooling medium flows through an inlet into a first line section ELA. At a branch point, a bypass BP branches off from the first line section ELA. A second valve V2, in particular a magnetically controlled valve, controls the flow of cooling fluid, such as water-containing cooling fluid. According to the position of the second valve V2 of the radiator HK and the heater HK upstream pump P is flowed with coolant or not flowed with coolant. When the second valve opens, cooling medium enters the heating element HK via the circulation pump P, flows through it and then flows in the direction of the outlet A. Before exiting, the bypass BP flows into the second line section ZLA. A first valve V1 controls the flow of cooling fluid or coolant through the bypass BP.

An dem flanschförmig ausgebildeten nicht näher bezeichneten Abschnitt ist der Bypassanschlussstutzen 16 mit dem Ventilgehäuse 5 formschlüssig, insbesondere durch Verschrauben und/oder stoffschlüssig, insbesondere durch Löten, Schweißen, Kleben usw. mit dem Ventilgehäuse 5 verbunden. Über den Bypassanschlussstutzen 16 wird ein nicht dargestelltes Schlauch- oder Rohrelement geschoben und beispielsweise mittels einer Schelle an dem Bypassanschlussstutzen 16 befestigt. In einem anderen Ausführungsbeispiel kann das nicht dargestellte Schlauchelement oder Rohrelement mit dem Bypassanschlussstutzen 16 formschlüssig und/oder stoffschlüssig verbunden sein. Insbesondere zum besseren Halt ist benachbart zu der Bypassanschlussöffnung 20 ein nicht bezeichneter Vorsprung aus dem Bypassanschlussstutzen ausgebildet, der insbesondere den Halt des auf den Bypassanschlussstutzen 16 geschobenen Rohrelements bzw. Schlauchelements verbessert.The bypass connecting piece 16 is at least partially tubular and has a bypass connection opening 20. At the end of the bypass connection piece, which is arranged opposite to the bypass connection opening 20, the bypass connection piece is designed in the shape of a flange. At the flange-shaped unspecified section of the bypass port 16 is positively to the valve housing 5, in particular by screwing and / or cohesively, in particular by soldering, welding, gluing, etc. with the valve housing 5 connected. About the bypass connection piece 16 a not shown tube or pipe element is pushed and attached, for example by means of a clamp on the bypass connection piece 16. In another embodiment, the hose element or pipe element, not shown, may be positively and / or materially connected to the bypass connection piece 16. In particular, for better support adjacent to the bypass port 20, a non-designated projection formed from the bypass port, which improves in particular the maintenance of the pushed onto the bypass port 16 pipe element or hose member.

Benachbart zu dem Bypassanschlussstutzen schließt sich ein im Wesentlichen zylinderförmig ausgebildeter erster Ventilgehäuseraum des ersten Ventilgehäuses 5 an, in dem das zweite Verschlusselement 8 sowie das zweite Federelement 12 angeordnet ist. Der erste Ventilgehäuseraum 29 weist eine nicht näher bezeichnete erste Öffnung auf, die benachbart zu dem Bypassanschlussstutzen 16 angeordnet ist. Ferner weist das Ventilgehäuse 5 eine zweite Ventilöffnung 4 auf, die insbesondere als Ventilsitz für das zweite Verschlusselement 8 ausgebildet ist. Der erste Ventilgehäuseraum 29 weist im dargestellten Ausführungsbeispiel einen größeren Durchmesser auf als der Bypassanschlussstutzen 16. Insbesondere wird damit zwischen dem ersten Verschlussgehäuseraum 29 und dem Bypassanschlussstutzen 16 ein Anschlag für das zweite Federelement 12 ausgebildet. In einem anderen Ausführungsbeispiel weist der Bypassanschlussstutzen einen größeren Durchmesser als der erste Ventilgehäuseraum 29 auf. In einem anderen Ausführungsbeispiel weist der erste Ventilgehäuseraum 29 den gleichen Durchmesser wie der Bypassanschlussstutzen 16 auf.Adjacent to the bypass connecting piece is followed by a substantially cylindrical first valve housing space of the first valve housing 5, in which the second closing element 8 and the second spring element 12 are arranged. The first valve housing chamber 29 has a unspecified first opening, which is arranged adjacent to the bypass connection piece 16. Furthermore, the valve housing 5 has a second valve opening 4, which is designed in particular as a valve seat for the second closure element 8. In the exemplary embodiment illustrated, the first valve housing space 29 has a larger diameter than the bypass connection piece 16. In particular, a stop for the second spring element 12 is formed between the first closure housing space 29 and the bypass connection piece 16. In another embodiment, the bypass connection piece has a larger diameter than the first valve housing space 29. In another embodiment, the first valve housing chamber 29 has the same diameter as the bypass connection piece 16.

Das zweite Federelement 12 ist im dargestellten Ausführungsbeispiel im Wesentlichen als Spiralfeder ausgebildet. In einem anderen Ausführungsbeispiel ist das zweite Federelement 12 beispielsweise als Blattfederelement oder als anderes Federelement ausgebildet.The second spring element 12 is formed in the illustrated embodiment substantially as a spiral spring. In another embodiment the second spring element 12 is formed for example as a leaf spring element or as another spring element.

Das zweite Verschlusselement 8 ist im Wesentlichen als kreisförmiges Plattenelement ausgebildet, aus welchem eine Noppe ausgebildet ist. Ist der Zufluss zum Bypass verschlossen, so liegt ein nicht näher bezeichneter ringförmiger Abschnitt des zweiten Verschlusselements 8 an einem Abschnitt des Ventilgehäuses 5 an. Der noppenförmige Abschnitt des zweiten Verschlusselements 8 ist im Wesentlichen in der zweiten Ventilöffnung 4 angeordnet. Ist der Bypasskanal geöffnet, so nimmt das zweite Verschlusselement beispielsweise die Position 30 ein, in der das zweite Verschlusselement gestrichelt dargestellt ist. Durch die zweite Ventilöffnung 4 kann dann Medium wie beispielsweise Kühlmedium, insbesondere eine wasserhaltige Kühlflüssigkeit, in den ersten Ventilgehäuseraum 29 eintreten und über den Bypassanschlussstutzen 16 in Richtung der zweiten Medienaustrittsöffnung M2A aus dem Ventil 1 austreten und in den nicht dargestellten Bypasskanal einströmen.The second closure element 8 is designed essentially as a circular plate element, from which a nub is formed. If the inflow to the bypass is closed, then an unspecified annular portion of the second closure element 8 bears against a section of the valve housing 5. The nub-shaped section of the second closure element 8 is arranged substantially in the second valve opening 4. If the bypass channel is open, the second closure element, for example, assumes the position 30, in which the second closure element is shown in dashed lines. By means of the second valve opening 4, medium such as, for example, cooling medium, in particular a water-containing cooling liquid, can then enter the first valve housing space 29 and exit from the valve 1 via the bypass connecting piece 16 in the direction of the second media outlet M2A and flow into the bypass channel (not shown).

In einem anderen Ausführungsbeispiel weist das zweite Verschlusselement 8 eine zumindest abschnittsweise kegelförmige und/oder zylinderförmige Form oder eine Form aus der Kombination der zuvor genannten Formen auf. Benachbart zu dem ersten Ventilgehäuseraum 29 schließt sich ein zweiter Ventilgehäuseraum 31 an. Über die Medieneintrittsrichtung strömt durch die Zuflussöffnung 19 des Zuflussstutzens 18 erstes Kühlmedium, insbesondere wasserhaltige Kühlflüssigkeit in den zweiten Ventilgehäuseraum 31 ein. Der Zuflussstutzen 18 weist im dargestellten Ausführungsbeispiel nicht näher bezeichnete zumindest abschnittsweise runde Nuten auf, die umlaufend um den Zuflussstutzen 18 ausgebildet sind. Auf diese Weise kann ein Schlauch- oder Rohrelement auf den Zuflussstutzen 18 aufgeschoben werden. Ein Ablösen des nicht näher bezeichneten Rohrelements oder Schlauchelements wird besonders vorteilhaft verhindert. Ferner kann beispielsweise das nicht dargestellte Schlauchelement mit dem Zuflussstutzen 18 mittels einer Schelle gesichert und/oder verbunden werden. In dem Ventilgehäuse 5 ist ein im Wesentlichen ringförmig ausgebildetes Element 33 eingebracht oder in einem anderen Ausführungsbeispiel einteilig mit dem Ventilgehäuse 5 ausgebildet. Das Ringelement 33 weist die erste Ventilöffnung 2 auf. Die erste Ventilöffnung 2 ist insbesondere als zumindest abschnittsweise konischer Ventilsitz für das erste Verschlusselement 3 ausgebildet. Benachbart zu dem zweiten Ventilgehäuseraum 31 und durch die erste Ventilöffnung 2 getrennt ist ein dritter Ventilgehäuseraum 32 ausgebildet. Bei geöffnetem ersten Verschlusselement 3 kann Kühlmedium wie beispielsweise wasserhaltige Kühlflüssigkeit oder Luft durch die erste Ventilöffnung 2 in den dritten Ventilgehäuseraum 32 eintreten und über den Heizkörperanschlussstutzen 17 aus der Heizkörperanschlussstutzenöffnung 21 in Richtung der ersten Medienaustrittsrichtung M1A austreten und beispielsweise zum nicht dargestellten Wärmetauscher, insbesondere zum nicht dargestellten Heizkörper, strömen. Das erste Verschlusselement 3 ist gestrichelt in der Verschlussstellung 34 dargestellt.In another embodiment, the second closure element 8 has an at least partially conical and / or cylindrical shape or a shape of the combination of the aforementioned forms. Adjacent to the first valve housing chamber 29, a second valve housing chamber 31 connects. Via the medium inlet direction flows through the inflow opening 19 of the inflow nozzle 18 first cooling medium, in particular water-containing cooling liquid in the second valve housing chamber 31 a. The inflow nozzle 18 has in the illustrated embodiment unspecified at least partially round grooves, which are formed circumferentially around the inflow pipe 18. In this way, a hose or pipe element can be pushed onto the inflow pipe 18. A detachment of the unspecified pipe element or hose member is particularly advantageously prevented. Further, for example, that can not shown hose member secured to the inflow pipe 18 by means of a clamp and / or connected. In the valve housing 5, a substantially annular element 33 is formed or formed integrally with the valve housing 5 in another embodiment. The ring element 33 has the first valve opening 2. The first valve opening 2 is designed in particular as at least partially conical valve seat for the first closure element 3. Adjacent to the second valve housing space 31 and separated by the first valve opening 2, a third valve housing space 32 is formed. When the first closure element 3 is open, cooling medium such as water-containing cooling liquid or air can enter the third valve housing space 32 through the first valve opening 2 and exit via the radiator connection stub 17 from the radiator connection stub opening 21 in the direction of the first media outlet direction M1A and, for example, to the heat exchanger, not in particular shown radiator, flow. The first closure element 3 is shown in dashed lines in the closed position 34.

Das erste Verschlusselement 3 ist konusförmig ausgebildet. An den konusförmigen Abschnitt schließt sich ein erstes Führungselement 9 an. Das erste Verschlusselement 3 und das erste Führungselement 9 sind im dargestellten Ausführungsbeispiel einteilig ausgebildet. In einem anderen Ausführungsbeispiel kann das erste Verschlusselement 3 und das erste Führungselement 9 stoffschlüssig, insbesondere durch Schweißen, Löten, Kleben usw. und/oder formschlüssig ausgebildet sein. Das erste Führungselement 9 ist im Wesentlichen als Stiftelement ausgebildet. In einem anderen Ausführungsbeispiel ist das erste Verschlusselement 3 zylinderförmig ausgebildet und weist eine runde oder ovale oder drei- oder mehreckige Querschnittsfläche oder eine Querschnittsfläche aus der Kombination der zuvor genannten Formen auf.The first closure element 3 is cone-shaped. At the cone-shaped portion, a first guide member 9 connects. The first closure element 3 and the first guide element 9 are integrally formed in the illustrated embodiment. In another embodiment, the first closure element 3 and the first guide element 9 can be integrally formed, in particular by welding, soldering, gluing etc. and / or in a form-fitting manner. The first guide element 9 is designed essentially as a pin element. In another embodiment, the first closure element 3 is cylindrical and has a round or oval or triangular or polygonal cross-sectional area or a cross-sectional area of the combination of the aforementioned forms.

Auf dem ersten Führungselement 9 ist zumindest abschnittsweise ein zweites Führungselement 25 angeordnet. Insbesondere ist das zweite Führungselement 25 auf das erste Führungselement 9 aufgeschrumpft oder beispielsweise durch Stoffschluss mit dem ersten Führungselement 9 verbunden. Das zweite Führungselement 25 ist im Wesentlichen als Zylinderkonuselement ausgebildet.At least in sections, a second guide element 25 is arranged on the first guide element 9. In particular, the second guide element 25 is shrunk onto the first guide element 9 or, for example, connected to the first guide element 9 by material connection. The second guide element 25 is designed essentially as a cylinder-cone element.

Das erste Verschlusselement 3 nimmt eine erste Endposition an, wenn das erste Führungselement 9 die erste Anschlagfläche 24 des Zylindergehäuses berührt. Die erste Anschlagfläche 24 kann beispielsweise Bestandteil eines Gummielements oder sonstigen Dämpfungselements zur Dämpfung des ersten Führungselements 9 sein. Insbesondere in der Verschlussstellung 34 des ersten Verschlusselements 3 berührt das Kegelelement des zweiten Führungselements 25 eine zugeordnete Kegelfläche des Führungsgegenelements 10. Das Führungsgegenelement 10 weist eine nicht näher bezeichnete Bohrung auf, die im Wesentlichen das erste Führungselement 9 aufnimmt. Auf diese Weise wird das erste Führungselement 9 zumindest abschnittsweise in der Bohrung des Führungsgegenelements 10 geführt. Das Führungsgegenelement 10 ist mit dem Ventilgehäuse 5 einteilig ausgeführt oder in einem anderen Ausführungsbeispiel mit dem Ventilgehäuse 5 formschlüssig und/oder stoffschlüssig verbunden. Zwischen dem zweiten Führungselement 25 und dem Führungsgegenelement 10 ist ein erstes Federelement 11 angeordnet. Das erste Federelement 11 kann beispielsweise als Spiralfeder oder als Blattfeder ausgebildet sein. Das erste Federelement 11 ist ferner auf dem ersten Führungselement 9 angeordnet. Befindet sich das erste Verschlusselement 3 insbesondere in der Verschlussstellung 34, so ist das erste Federelement 11 derart vorgespannt, dass im stromlosen Zustand des Ventils 1 eine Federkraft auf das zweite Führungselement 25 und ebenso auf das Führungselement 10 wirkt, so dass das zweite Führungselement 25 und das Führungsgegenelement 10 auseinandergedrückt werden und das erste Verschlusselement die erste Ventilöffnung frei gibt. Im stromlosen Zustand ist also gewährleistet, dass erstes Medium, insbesondere Kühlmedium wie insbesondere die wasserhaltige Kühlflüssigkeit aus dem Heizkörperanschlussstutzen 17 über die Heizkörperanschlussstutzenöffnung 21 in Richtung der ersten Medienaustrittsrichtung M1A austreten kann. Das erste Führungselement 9 sowie das zweite Führungselement 25 sind insbesondere aus einem magnetisierbaren Material wie beispielsweise Metall, insbesondere Eisen oder Aluminium oder einem Stahl ausgebildet. Im Wesentlichen konzentrisch zu dem ersten Führungselement 9 und/oder zu dem zweiten Führungselement 25 ist eine Spule 6 bzw. ein Elektromagnet 7 in dem Ventilgehäuse 5 angeordnet. Die Spule 6 bzw. der Elektromagnet 7 werden über einen elektrischen Anschluss mit Strom versorgt. Wird die Spule 6 bzw. der Elektromagnet bestromt, so wird eine Magnetkraft MK erzeugt, die das erste Verschlusselement 3 bzw. das erste Führungselement 9 in Richtung der Magnetkraft MK bewegt, so dass das erste Verschlusselement 3 die Verschlussstellung 34 einnimmt und die erste Ventilöffnung 2 verschließt. Das erste Verschlusselement 3 ist beispielsweise aus einem Material wie Gummi oder aus einem anderen Dichtmaterial ausgebildet, so dass in der Verschlussstellung 34 des ersten Verschlusselements 3 kein Medium wie beispielsweise Kühlmedium durch die erste Ventilöffnung 2 in den dritten Ventilgehäuseraum 32 aus dem zweiten Ventilgehäuseraum 31 eintreten kann.The first closure element 3 assumes a first end position when the first guide element 9 contacts the first stop surface 24 of the cylinder housing. The first stop surface 24 may for example be part of a rubber element or other damping element for damping the first guide element 9. In particular, in the closed position 34 of the first closure element 3, the cone element of the second guide element 25 contacts an associated conical surface of the guide counter element 10. The guide counter element 10 has an unspecified bore, which essentially accommodates the first guide element 9. In this way, the first guide element 9 is guided at least in sections in the bore of the guide counter-element 10. The guide counter-element 10 is made in one piece with the valve housing 5 or in another embodiment with the valve housing 5 positively and / or materially connected. Between the second guide member 25 and the guide counter-element 10, a first spring element 11 is arranged. The first spring element 11 may be formed, for example, as a spiral spring or a leaf spring. The first spring element 11 is further arranged on the first guide element 9. If the first closure element 3 is in particular in the closed position 34, then the first spring element 11 is pretensioned such that a spring force acts on the second guide element 25 and also on the guide element 10 in the currentless state of the valve 1, so that the second guide element 25 and the guide counter-element 10 are pressed apart and the first closure element releases the first valve opening. in the de-energized state is thus ensured that the first medium, in particular cooling medium such as in particular the aqueous coolant can escape from the radiator connection piece 17 via the radiator connection port 21 in the direction of the first media exit direction M1A. The first guide element 9 and the second guide element 25 are in particular made of a magnetizable material such as metal, in particular iron or aluminum or a steel. Essentially concentric with the first guide element 9 and / or with the second guide element 25, a coil 6 or an electromagnet 7 is arranged in the valve housing 5. The coil 6 and the electromagnet 7 are powered by an electrical connection. When the coil 6 or the electromagnet is energized, a magnetic force MK is generated which moves the first closure element 3 or the first guide element 9 in the direction of the magnetic force MK, so that the first closure element 3 assumes the closure position 34 and the first valve opening 2 closes. The first closure element 3 is formed, for example, from a material such as rubber or from another sealing material, so that in the closed position 34 of the first closure element 3 no medium such as cooling medium through the first valve opening 2 in the third valve housing chamber 32 from the second valve housing chamber 31 can occur ,

Ferner ist auf dem ersten Führungselement 9 eine Membran 14 derart angeordnet, dass sie Schmutz von dem ersten Führungselement 9 befreit und gleichzeitig den Raum 32 gegenüber einem vierten Ventilgehäuseraum 35 abdichtet. In dem vierten Ventilgehäuseraum 35 sind insbesondere der Elektromagnet 7 sowie die Spule 6, das erste Federelement 11 und das zweite Führungselement 2 angeordnet. Die Membran 14 weist eine im Wesentlichen mit der Querschnittsfläche des ersten Führungselements 9 korrespondierende Öffnung auf. Die Membran 14 ist beispielsweise aus Gummi oder einem sonstigen Dichtmaterial ausgebildet. Im dargestellten Ausführungsbeispiel ist die Membran 14 einteilig mit einem ersten Dichtungselement 22 ausgebildet. In einem anderen Ausführungsbeispiel sind das erste Dichtungselement 22 und die Membran 14 nicht einteilig ausgebildet. Das erste Dichtungselement 22 ist beispielsweise aus Gummi oder aus einem anderen Dichtmaterial ausgebildet und verhindert, dass Medium vom dritten Ventilgehäuseraum 32 in den vierten Ventilgehäuseraum 35 eintritt und beispielsweise die Spule 6 oder den zumindest einen Elektromagneten 7 sowie die elektrischen Anschlüsse 13 schädigt, indem beispielsweise Flüssigkeit wie beispielsweise Kühlmedium oder anderes Medium in den vierten Ventilgehäuseraum 35 eintritt. Zumindest ein zweites Dichtungselement 23 und/oder zumindest ein drittes Dichtungselement 27 verhindert ebenfalls, dass beispielsweise Medium wie insbesondere Kühlmedium, insbesondere wasserhaltige Kühlflüssigkeit, zu dem zumindest einen Elektromagneten bzw. zu der zumindest einen Spule 6 gelangt und diese schädigt.Further, on the first guide member 9, a diaphragm 14 is arranged such that it frees dirt from the first guide member 9 and at the same time the space 32 against a fourth valve housing chamber 35 seals. In particular, the electromagnet 7 and the coil 6, the first spring element 11 and the second guide element 2 are arranged in the fourth valve housing space 35. The membrane 14 has an opening substantially corresponding to the cross-sectional area of the first guide element 9. The membrane 14 is formed for example of rubber or other sealing material. In the illustrated embodiment the membrane 14 is integrally formed with a first sealing element 22. In another embodiment, the first sealing element 22 and the membrane 14 are not formed in one piece. The first sealing element 22 is formed for example of rubber or other sealing material and prevents medium from the third valve housing chamber 32 enters the fourth valve housing chamber 35 and, for example, the coil 6 or the at least one electromagnet 7 and the electrical connections 13 damages, for example by liquid such as cooling medium or other medium enters the fourth valve housing chamber 35.
