Abstract
Component of tank of liquid additive of system for treating exhaust gases of internal combustion engine, has body positioned in fluid-tight way at opening of the tank and incorporates plurality of functional devices for managing liquid additive to be delivered to treatment system. Body of tank component is moulded using plastic material chemically resistant to liquid additive and is provided with at least one passageway for liquid additive. The plurality of functional devices comprises pump and pressure sensor having pressure-sensitive element. Passageway comprises delivery path for the liquid additive, which is defined at least in part in first wall of body of tank component and has inlet end configured for connection to delivery duct of the pump. Defined at outer side of first wall is at least one seat for positioning at least one part of pressure sensor. Moreover defined in the first wall is at least one passage for setting delivery path for liquid additive in fluid communication with sensitive element of pressure sensor.
