Abstract

Die Erfindung betrifft eine AGR-Regelung mit mechanischer Temperaturregelung. Eine derartige AGR-Regelung wird an Brennkraftmaschinen (1) mit einer Ansaugleitung (2) zur Zuführung der Ansaugluft zu den einzelnen Brennräumen (3), mit einer Abgasleitung (4) zur Abführung der Abgase aus den Brennräumen (3) und mit einer die Ansaugleitung (2) und die Abgasleitung (4) verbindenden Abgasrückführleitung (5) verwendet, wobei in der Abgasleitung (4) ein Temperatursensor angeordnet ist, dessen Temperaturwert zur Steuerung der durch die Abgasrückführleitung (5) rückgeführten Abgase verwendet wird. Erfindungsgemäß ist der Temperatursensor ein mechanisches Thermoelement (6), dessen temperaturabhängige Auslenkung eine Abgasklappe (7) mechanisch steuert.
