Abstract: Proposed is a dosing module for injecting liquid urea-water solution into the exhaust tract of an internal combustion engine, which dosing module is composed of two pumps, specifically a delivery pump (5) and an aeration pump (15). This permits firstly the injection of urea-water solutions and secondly safe and reliable ventilation of the system when the internal combustion engine is to be shut down.

Abstract: 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.

Abstract: The invention relates to a liquid removal module (1) for removing liquid from a liquid tank (18), in particular of an exhaust gas aftertreament system of a motor vehicle, comprising a main body (2) that can be arranged in and/or on the liquid tank (18). The main body has a liquid removal device (36) having at least one removal opening (7) that can be associated with the tank interior (27) and bears at least one filter element (9) associated with the removal opening (7). The filter element (9), which is elastically deformable at least in some areas, is arranged/designed in such a way that the filter element has at least one bulge (17) directed opposite the removal flow direction (26). The invention further relates to a liquid tank (18) for a vehicle, in particular for an exhaust gas aftertreament system of a motor vehicle.

Abstract: A pressure-measuring device is situated in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmitting element that protrudes partly from the housing at a chamber-side opening of the housing, and a pressure sensor that is situated in an interior space of the housing. The pressure sensor stands in effective connection to the force-transmitting element. In addition, a diaphragm is provided that seals the interior space of the housing, in which the pressure sensor is situated, against the chamber-side opening. The diaphragm, which is preferably fashioned as a metal diaphragm, has a force-transmitting segment that is oriented in an axial direction of the force-transmitting element. Moreover, the pressure sensor stands in effective connection with the force-transmitting element via the force-transmitting segment of the diaphragm.

Abstract: A pressure-measuring device is to be placed in a chamber of an internal combustion engine. The pressure-measuring device has a housing, a force-transmission element projecting out of the housing, and a pressure sensor disposed in an interior chamber of the housing. On the one hand, the pressure sensor is braced on a fixation element. On the other hand, to detect a pressure prevailing inside the chamber, the pressure sensor is operatively connected to the force-transmission element. The pressure sensor has a straight-through recess through which an electrical line is routed. In addition, a positioning element is provided, which has a straight-through recess in a guide region, the electrical line being routed through the straight-through recess, and the positioning element having a reduced thickness in the guide region. This makes it possible to reduce friction of the electrical line in the guide region at the straight-through recess, so that the pressure measurement is improved.
