                Application 10/479,696                                                                       


                connected to the relief valve, and the additional line is connected to the                   
                pneumatic connection.                                                                        
                      21.  The device according to claim 13, wherein the pressure                            
                recording element includes a pressure sensor.                                                
                      22.  The device according to claim 21, further comprising a                            
                regulator connected to the pressure sensor and integrated into a control unit                
                which is adapted to control the means for regulating and the metering device                 
                as a function of the pressure changes.                                                       
                      25.  The device according to claim 13, wherein the metering device                     
                is mounted on an exhaust gas pipe that leads to the catalytic converter                      
                system, the output side of the metering device facing away from the line                     
                penetrating into the exhaust gas pipe.                                                       
                      26. A method for metering a reducing agent comprising:                                 
                      supplying the reducing agent in a metered manner to a catalytic                        
                converter system for a removal of nitrogen oxides from exhaust gases with                    
                the aid of a metering device,                                                                
                      regulating a pressure of the reducing agent; and                                       
                      recording pressure changes at a side of the metering device facing the                 
                catalytic converter system, the pressure changes having an influence on the                  
                pressure regulation.                                                                         
                      The Examiner relies on the following prior art reference as evidence                   
                of unpatentability:
