Abstract

The circulatory cooling requires channels (4,7) in the valve (1) on the compression side, connected on the induction side to channels (15,12) via the dish cavity. The coolant comes in via the annular compression channel (6) and goes out via the annular induction channel (13). The height of the annular channels corresponds to the max. lift of the valve. This ensures a continuous supply of coolant. Due to the offset position of the annular channels, the coolant also rotates the valve.

Description

Die Erfindung betrifft eine Vorrichtung zur Kühlung von Ventilen nach der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a device for cooling valves according to the preamble of Claim 1 mentioned type.

Ventile dieser Art werden in vielfältigen Technologien und Ausführungsformen hergestellt.Valves of this type are manufactured in a variety of technologies and designs.

Die Vorrichtung der Eingangs genannten Art unterscheidet sich in Bezug auf den Stand der Technik vorrangig dadurch, daß nicht das in das Ventil hermetisch dicht eingeschlossene Natrium als oszillierendes Kühlmittel fungiert, sondern daß während des Ventilbetriebs eine kontinuierliche Kühlung des Ventils mittels eines umlaufenden Kühlmittels ermöglicht wird.The device of the type mentioned differs in relation to the prior art primarily because the sodium, which is hermetically sealed in the valve, does not oscillate Coolant acts, but that means a continuous cooling of the valve during valve operation a circulating coolant is made possible.

Ausgehend von dem zuvor genannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine funktionssichere und kostengünstige Ventilkühlung nach der im Oberbegriff des Anspruch 1 genannten Art, als Ventilumlaufkühlung einsetzen zu können.Starting from the aforementioned prior art, the invention is based on the object Reliable and inexpensive valve cooling according to the type mentioned in the preamble of claim 1 To be able to use valve circulation cooling.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind durch die von diesem Anspruch abhängigen Ansprüche gekennzeichnet.This problem is solved by the characterizing features of claim 1. Advantageous Further developments of the invention are characterized by the claims dependent on this claim.

In Folgendem wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit einer Zeichnung beschrieben. Dabei zeigtIn the following the invention based on a preferred embodiment in conjunction with a Drawing described. It shows

Fig. 1 eine vereinfachte Schnittzeichnung des Ventils (1) mit dem Druckkanaleinlaß (4), den Druckkanal (7), der über den Tellerhohlraum (17) mit dem Saugkanal (15) und dem Saugkanalauslaß (12) derart verbunden ist, daß die auf der Druckseite und in die Ventilführung (3) eingelassenen Elemente in Form der Druckleitung (5) in den Druckringkanal (6) gedrückte Kühlmittel, als Motoröl oder andere Kühlmittel, nach Durchströmung und Kühlung der zuvor genannten Räume, auf der Saugseite über den Saugringkanal (13) und die Saugleitung (14) wieder austritt, um dem Kühlkreislauf erneut wieder zugeführt zu werden. Die Höhe des Druckringkanals (6) und des Saugringkanals (13) sind mindestens so hoch, wie der maximale Ventilhub lang ist, um eine laufende Kühlung während des Ventilbetriebs sicherzustellen. Da die Fläche des Ventilsitzes (16) und die Wandung des Ventilschaftes (11) einer starken Abnutzung unterliegen und eine zusätzliche laufende Reinigung dieser Flächen erwünscht ist, dreht das Ventil nach dem Stand der Technik während des Betriebs über eine Ventildrehvorrichtung. Daher ist eine Trennung von Einlaß und Auslaß der Umlaufkühlung in Form des versetzten Druckringkanals (6), gegenüber dem des Saugringkanals (13), vorgesehen. Fig. 1 is a simplified sectional drawing of the valve ( 1 ) with the pressure channel inlet ( 4 ), the pressure channel ( 7 ), which is connected via the plate cavity ( 17 ) with the suction channel ( 15 ) and the suction channel outlet ( 12 ) such that the on the pressure side and in the valve guide ( 3 ) elements in the form of the pressure line ( 5 ), coolant pressed into the pressure ring channel ( 6 ), as engine oil or other coolant, after flowing through and cooling the previously mentioned spaces, on the suction side via the suction ring channel ( 13 ) and the suction line ( 14 ) exits again in order to be fed back into the cooling circuit. The height of the pressure ring channel ( 6 ) and the suction ring channel ( 13 ) are at least as high as the maximum valve stroke is long in order to ensure ongoing cooling during valve operation. Since the surface of the valve seat ( 16 ) and the wall of the valve stem ( 11 ) are subject to severe wear and tear and an additional ongoing cleaning of these surfaces is desired, the valve according to the prior art rotates during operation via a valve rotating device. Therefore, a separation of the inlet and outlet of the circulation cooling in the form of the offset pressure ring channel ( 6 ), compared to that of the suction ring channel ( 13 ) is provided.
