Liquid reducing agent tank for emission control device of lorry, has removal filters for separating reducing agents from tank, filler pipe conveying agents into tank and comprising prefilter, and pocket region arranged at outlet end of pipe

摘要

#CMT# #/CMT# The tank (1) has removal filters for separating reducing agents from the tank. A filler pipe (5) conveys the reducing agents into the tank and comprises a prefilter (8) i.e. pocket filter. A pocket region (9) of the pocket filter adjacent to the filler pipe has larger dimensions in a longitudinal section viewed along radial direction. The pocket region is arranged at an outlet end (7) of the filler pipe, and a secondary filter region (10) of the pocket filter extends up to an inlet end (6) of an inlet port. A holding unit (14) is designed as a clamping ring (15). #CMT#USE : #/CMT# Liquid reducing agent tank for an emission control device (claimed) of a motor vehicle i.e. lorry. #CMT#ADVANTAGE : #/CMT# The removal filters separate the reducing agents from the tank, and the filler pipe conveys the reducing agents into the tank and comprises the prefilter such that the removal filters filter out dirt sucked with the reducing agent in the reducing agent tank to prevent clogging of metering valve associated with an emission control device or conveyor and damage to operability of the emission control device. The tank exhibits increased service life and low manufacturing cost, and avoids utilization of additional filter materials. The tank prevents damages of the emission control device from the metering valve and the conveyor of a removal device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional perspective view of a reducing agent tank for an emission control device of a motor car with a filler pipe, which comprises a prefilter. 1 : Reducing agent tank 5 : Filler pipe 6 : Inlet end of inlet port 7 : Outlet end of filler pipe 8 : Prefilter 9 : Pocket region 10 : Secondary filter region 14 : Holding unit 15 : Clamping ring.
