Liquid extraction module, liquid tank

摘要

The invention relates to a liquid extraction module (1) for extracting liquid from a liquid tank, in particular of an exhaust-gas aftertreatment system of a motor vehicle, comprising a basic body (2) which can be arranged in and/or on the vehicle tank and which bears a liquid extraction device (6) with an extraction orifice (5) that can be assigned to the tank interior, and at least one electric heating element (20). According to the invention, at least one heat-conducting element (18) is provided, said element having at least one first portion (24) assigned to the heating element (20) and one second portion (25) assigned to the extraction orifice (5), in order to transport the heat from the heating element (20) to the extraction orifice (5). The invention further relates to a liquid tank for a vehicle.
