VALVE SEAT DEVICE FOR A METERING VALVE OF AN EXHAUST TREATMENT STATION |
摘要 |
<p>An uncontrolled heat pipe (20) is used in a valve seat device (19) for transferring the waste heat from the exhaust gas acting on the metering valve (15) to a condensation zone (21) which is situated in an environment which is at a lower temperature, whereby the metering valve is cooled sufficiently to prevent a chemical change of a reducing agent which otherwise can be caused by high temperatures.</p> |
