Abstract
Die Erfindung geht aus von einem Failsafe-Ventil (38, 50, 57) für die Verwendung in einem Kühlwasserkreislauf eines Kraftfahrzeuges, mit einem Ventilraum (40, 52), einem mit dem Ventilraum (40, 52) verbundenen Ein- und Auslasskanal (43, 56, 58), sowie mit mindestens einem den Auslasskanal (43, 56, 58) überwachenden Stellglied. Es wird vorgeschlagen, dass das Stellglied als Bimetallelement (42, 54, 60, 62) ausgebildet ist.The invention is based on a fail-safe valve (38, 50, 57) for use in a cooling water circuit of a motor vehicle, with a valve chamber (40, 52), an inlet and outlet channel (43) connected to the valve chamber (40, 52) , 56, 58), and with at least one actuator that monitors the outlet channel (43, 56, 58). It is proposed that the actuator be designed as a bimetal element (42, 54, 60, 62).
Description
Die vorliegende Erfindung geht aus von einem Failsafe-Ventil für einen Kühlwasserkreislauf eines Kraftfahrzeuges gemäß den Merkmalen der Oberbegriffe der Ansprüche 1 und 9.The present invention is based on a failsafe valve for a cooling water circuit of a motor vehicle according to the features of the preambles of claims 1 and 9.
Aus der
Aufgabe der Erfindung ist es im vorliegenden Fall, ein konstruktiv einfaches, kostengünstiges und zuverlässig funktionierendes Ventil bereit zu stellen, welches bei einer Fehlfunktion eines im Kühlwasserkreislauf angeordneten Regelventils eine Grundkühlleistung sicherstellt, die eine Überhitzung des Motors bzw. entsprechender Komponenten davon, zuverlässig verhindert.The object of the invention is to provide in the present case, a structurally simple, inexpensive and reliable functioning valve, which ensures a malfunction of arranged in the cooling water control valve control a basic cooling capacity, which reliably prevents overheating of the engine or corresponding components thereof.
Die Lösung der Aufgabe erfolgt dabei durch die im Anspruch 1 und 9 angegebenen Merkmale.The solution of the problem is carried out by the features specified in claim 1 and 9 features.
Das Failsafe-Ventil besteht im wesentlichen aus einem Failsafe-Kanal, der durch eine temperaturempfindliches Stellglied in Form eines Bimetallelements überwacht ist. Durch den Einsatz nur weniger Bauteile ist das Failsafe-Ventil robust und funktionssicher und schützt damit den Motor bei einem Ausfall der Ansteuerung oder bei einem Blockieren des Ventils zuverlässig vor Überhitzung.The failsafe valve consists essentially of a failsafe channel, which is monitored by a temperature-sensitive actuator in the form of a bimetallic element. By using only a few components, the fail-safe valve is robust and functionally reliable, thus reliably protecting the motor from overheating in the event of a drive failure or blocking of the valve.
In den Unteransprüchen sind weitere vorteilhafte Ausgestaltungen und Verbesserungen des erfindungsgemäßen Kühlkreislaufs sowie des Failsafe-Ventils aufgeführt.In the dependent claims further advantageous embodiments and improvements of the cooling circuit according to the invention and the failsafe valve are listed.
In einer ersten vorteilhaften Ausführungsform ist das Bimetallelement in einem Ventilgehäuse einseitig fixiert und dichtet den Failsafe- Kanal in axialer Richtung ab.In a first advantageous embodiment, the bimetallic element is fixed on one side in a valve housing and seals off the failsafe channel in the axial direction.
In einer zweiten vorteilhaften Ausführungsform ist das Bimetallelement wiederum einseitig im Ventilgehäuse eingespannt bzw. befestigt und verschließt bzw. öffnet den Failsafe- Kanal in tangentialer Richtung.In a second advantageous embodiment, the bimetallic element is in turn clamped or fastened on one side in the valve housing and closes or opens the failsafe channel in the tangential direction.
In einer dritten vorteilhaften Ausführungsform sind zwei Bimetallelemente als Stellglied vorgesehen, die jeweils diametral gegenüber liegend am bzw. im Failsafe- Kanal befestigt sind und sich entsprechend überlappen, so dass der Failsafe- Kanal stirnseitig verschlossen, oder freigeben wird.In a third advantageous embodiment, two bimetallic elements are provided as an actuator, which are each mounted diametrically opposite lying on or in Failsafe- channel and overlap accordingly, so that the failsafe channel is closed at the front, or release.
Drei Ausführungsbeispiele der Erfindung sind in der nachfolgenden Beschreibung und Zeichnung näher erläutert.Three embodiments of the invention are explained in more detail in the following description and drawings.
