Abstract: A vehicle system storing an aqueous solution includes: a first compartment; a second compartment; a module that includes a feed pump unit connected for pumping aqueous solution from the first compartment to a feed outlet; and a jet pump having a suction inlet, a pressure inlet and an outlet. The feed pump unit is further connected for pumping aqueous solution along a flow path from the first compartment through the feed pump unit, through the pressure inlet of the jet pump to the outlet of the jet pump. A heater heats the flow path. The suction inlet is connected to a suction line that receives the aqueous solution from the second compartment. The outlet of the jet pump returns aqueous solution from the suction inlet and from the pressure inlet to the first compartment.

Abstract: The invention relates to a pump (2) intended to pump an additive in an SCR system for a vehicle. The pump is configured to rotate in a first direction of rotation in order to convey additive stored in a tank towards an injector via an injection channel. The pump includes a chamber (23) which houses a gear system (22). The chamber (23) is in fluid communication with the tank and the injection channel via an inlet channel (24) and an outlet channel (25) respectively. The pump is such that the inlet channel and the outlet channel are arranged so that after draining the injection channel, the chamber collects and retains the additive.
