A method of regenerating an exhaust gas purification filter, in particular for internal combustion engines, uses a vaporized liquid that is to be introduced into the exhaust gas flow. A surface temperature of a heating element in a vaporizer chamber is limited to a maximum of 700 to 750&#xb0; C.

A valve device, in particular for an exhaust system of an internal combustion engine, has a valve flap which is arranged in a tube and can assume a basic position and an actuating position. A motor-driven valve drive that is arranged outside the tube and is coupled to a shaft of the valve flap by a force transmission element. A mechanical restoring element urges the valve flap into the basic position. The valve drive works against the mechanical restoring element as far as to the actuating position. A lever is connected to one end of the force transmission element and when in the actuating position of the valve flap, is in or near the dead-center position with respect to the force transmission direction from or to the force transmission element. In an alternative configuration, the lever is coupled to the shaft of the valve flap and, in the actuating position of the valve flap, is in a position in which the distance between the force transmission direction from or to the force transmission element and the pivot axis of the lever is at least approximately a maximum.

A muffler for pulsating gases, especially exhaust gases of internal combustion engines, comprises a housing into which an inlet conduit enters, from which at least on outlet conduit exits and which is divided by at least one partition wall into at least two chambers. In this muffler the flow cross section of a flow path connecting two chambers and/or of an outlet conduit can be varied by means of an adjustable closure element. An actuating element acting on the closure element is provided in the region of the exit cross section of the inlet conduit.
