摘要： Disclosed is a filter device (10), particularly a liquid filter, comprising a filter element (16) that is disposed in a filter housing (12, 14) and a heater (28) for heating medium flowing through the filter device (10). The inventive filter device (10) is characterized in that the heater (28) is designed with at least one heating circuit (30) that is molded into the filter housing (12, 14). Alternatively or additionally, the heater (28) is designed with at least one heating circuit (30) which is provided with an electrical contact (34) in at least one of the final zones thereof, said electrical contact (34) being riveted to the heating circuit (28).

摘要： The invention is based on an exhaust gas aftertreatment device for the aftertreatment of exhaust gases in an exhaust gas system of an internal combustion engine in which a catalyst for the reduction of NOx constituents of the exhaust gas of the internal combustion engine is arranged, and having a device for introducing a reducing agent via an exhaust gas pipe (11) into the catalyst, wherein the device comprises a metering valve (10). It is proposed that the exhaust gas pipe (11) be designed for avoiding direct input of heat into the metering valve (10) and/or for permitting increased heat dissipation from the metering valve (10).

摘要： The invention relates to a dosing valve system comprising a dosing valve (12) for proportioning a liquid, especially an aqueous urea solution used for aftertreating exhaust gases from combustion engines, the liquid being conveyed to the dosing valve (12) in a specific transport direction (24). A mixing chamber (13) is provided in which the liquid can be mixed with a gas in a gas flow. According to the invention, the dosing valve (12) can be emptied counter to the transport direction (24).

摘要： The invention relates to a device for the post-treatment of exhaust gases of an internal combustion engine, using a reductant that is to be introduced into the exhaust gases, in particular urea or a urea-water solution, comprising a mixing chamber, or relates to a mixing chamber, into which stored reductant can be introduced via a reductant conduit and compressed air can be introduced via a compressed air conduit to create a reductant-air mixture. The invention is provided with elements for preventing a reflux of reductant or the reductant-air mixture from the mixing chamber into the compressed air conduit. Said elements have a spring-loaded (112, 114) sealing hose (110). Said arrangement ensures that a connectable compressed air system can be reliably sealed against the corrosive reductant.
