Abstract

Eine Vorfilteranordnung für Gasanalysesysteme, insbesondere für Abgasanalysesysteme für Verbrennungskraftmaschinen, weist in einem gemeinsamen Gehäuse einen Eingangsanschluss (1) für die Probenahmeleitung, daran anschließend ein Einlassventil (2), ein Haupt-Filterelement (3), ein Auslassventil (4) und einen Ausgangsanschluss (5) für die Leitung zum Gasanalysesystem auf. Gegebenenfalls kann eine Schnittstelle zu einer Steuereinrichtung und gegebenenfalls auch zumindest eine interne Temperaturregeleinrichtung integriert sein.Um bei kompaktem Aufbau einen flexibleren Einsatz und mehr Möglichkeiten für unterschiedliche Betriebsarten zu bieten, ist am oder unmittelbar hinter dem Einlassventil (2) zusätzlich ein weiterer Anschluss für eine Spül- und/oder Testgasleitung (11) vorgesehen, und ist am Auslassventil (4) oder unmittelbar davor zusätzlich ein Eingangsanschluss für eine Rückspülleitung (15) vorgesehen.A pre-filter arrangement for gas analysis systems, in particular for exhaust gas analysis systems for internal combustion engines, has in a common housing an inlet connection (1) for the sampling line, subsequently an inlet valve (2), a main filter element (3), an outlet valve (4) and an outlet connection ( 5) for the line to the gas analysis system. Optionally, an interface to a control device and possibly also at least one internal temperature control device be integrated. In order to offer a more flexible use and more options for different operating modes in a compact design, is on or immediately behind the inlet valve (2) additionally another connection for a purge - And / or test gas line (11), and is provided at the outlet valve (4) or immediately before an additional input port for a backwash line (15).
