Gaswechselventil und Verfahren zum Messen des Druckes in einem Brennraum einer Brennkraftmaschine

摘要

The head (81) of a gas shuttle valve presents on its front face a valve seat (84) which is designed preferably, at least partly, as a membrane (90) and which, owing to the pressure prevailing inside the combustion chamber (83), undergoes a deformation. This deformation can be transferred through a valve stem (82) to a position sensor, with the result that the pressure inside the combustion chamber can be measured (13).
