Abstract: The invention relates to a metering device (10) for introducing a process liquid or auxiliary agent into a flow pipe of an internal combustion engine, in particular for introducing a reducing agent into an exhaust gas pipe (12). Said device comprises an injection valve (22) and a receiving device (50) comprising a heat sink element (46) and a cover element (48). The injection valve (22) and the receiving device (50) are combined to form a structural unit by means of bonded connections (62, 64).

Abstract: The invention relates to a metering module (10) for metering a reduction means in an exhaust system of an internal combustion engine. The metering module (10) comprises at least one cooling element (22, 24) through which cooling fluid flows. The metering module (10) has a cooled connection piece (44) that is actively cooled by the cooling fluid.

Abstract: The invention relates to a device for cooling a metering module (10) for dispensing a process liquid/auxiliary agent into the exhaust gas system of an internal combustion engine. The metering module (10) comprises a housing (12) with a plurality of housing sections (19), (20), (28), (29). A first housing section (19), (20), on which a supply line (18) for the process liquid/auxiliary agent is located, is situated in a region (62) of the metering module (10) that is exposed to varying temperatures, said section being made of metal.

Abstract: The invention relates to a metering module (10) including a metering valve (12). The metering module further includes a cooling device through which a cooling fluid flows. Said cooling device comprises a first chamber (26) that has a cooling fluid inlet (42). The metering valve (12) has an additional cooling member (36) containing a second chamber (52) which is hydraulically connected to the first chamber (26) via at least one opening (50).

Abstract: A method for granulating a particle-containing material from an industrial process includes mixing the particle-containing material in the presence of water with a material that consists of or comprises a water-absorbing and swellable organic polymer compound which is insoluble in water so as to obtain granulates.

Abstract: The invention relates to a dosing module (10) for metering a reducing agent into an exhaust system of an internal combustion engine. Said dosing module (10) comprises at least one cooling member (22, 24) through which a cooling fluid flows that is used to cool the internal combustion engine. An electric contact (20) is located in the top region of the dosing module (10). The dosing module (10) is enclosed in a full housing (38) that comprises an upper and a lower cooling member (22, 24, 24) through which a directed cooling fluid stream (34) flows that runs from the valve tip region (18) in the direction of the electric contact (20).
