Systems, methods, and devices are disclosed. In an exemplary embodiment, a heating device for heating liquids in a reservoir, such as a tank or a container of a vehicle is disclosed. The heating device may have a housing which is resistant to the liquid to be heated and has a tubular outer casing closed at one end by a base part and at the other end by a cover part. The heating element may also include an insert inserted into the outer casing of the housing and at least one surface heating element arranged between the outer casing and the insert. Connecting conductors of the heating element may be routed out of the housing sealed, and at least one surface heating element may cover the inner surface of the outer casing, viewed in the circumferential direction of the outer casing, at least over a partial circumference, with which the outer casing may be in thermal contact, and the insert, or at least parts thereof, may be pretensioned and press the at least one surface heating element against the inner surface of the outer casing at least in partial regions.

A method for operating a pump assembly, wherein the pump assembly has at least one first drive means for conveying a fluid and an electric motor for driving the first drive means, the electric motor comprising at least one stator and one rotor, the rotor being connected at least to the first drive means via a driveshaft. The electric motor draws power at least: i. in order to heat the rotor by means of induction; or ii. in order to drive the rotor, the driveshaft and the first drive means so that these components rotate about a common rotation axis at a speed of more than 0 revolutions per minute.

An apparatus comprises a reductant storage tank configured to store a reductant, and a reductant delivery conduit. A first end of the reductant delivery conduit is fluidly coupled to the reductant storage tank. A second end of the reductant delivery conduit opposite the first end is configured to be fluidly coupled to a connector of a reductant insertion assembly. At least one bend having a bend angle is provided in the reductant delivery conduit along a length thereof, the at least one bend being configured to inhibit failure at an interface between the second end of the reductant delivery conduit and the connector of the reductant insertion assembly due to freezing of a reductant in the reductant delivery conduit.

A base filter for a diesel exhaust fluid (DEF) filter of a header assembly in a fluid reservoir is disclosed may include first and second semi-cylindrical holder portions having a semi-cylindrical walls concluding at abutment surfaces that face and engage when the base filter is assembled. The semi-cylindrical holder portions have one or more mounting tabs extending inward from inner surfaces of the semi-cylindrical walls. The header assembly may include a header with a cylindrical header boss having mounting recess defined therein. The mounting tabs may be circumferentially spaced about the semi-cylindrical walls to align with and be inserted into the mounting recesses of the header boss the base filter is assembled on the cylindrical header boss. Fasteners may be inserted through fastener bosses of the semi-cylindrical holder portions and into fastener bores of the header boss to hold the semi-cylindrical holder portions together and on the header.

The disclosure relates to a conduit connector for a fluid line, having a housing, which has at least one first connection geometry and one second connection geometry, each for connecting to a fluid line. In the housing, a fluid-conducting channel is formed between the first connection geometry and the second connection geometry. In order to avoid damage due to freezing of a liquid located in the channel or the connected fluid lines, the housing has a volume equalization device, which is connected to the channel.

A metering device for metering water or an aqueous solution, such as an injector for metering a reducing agent liquid into an exhaust gas stream of a combustion system or an injector for metering water or aqueous solution into a combustion chamber or into an intake manifold of an internal combustion engine. The metering device has an inlet and an outlet for the water or aqueous solution and a shut-off device which is arranged between the inlet and the outlet. At least one electrically operated heating element is arranged in the region of the shut-off device so as to heat and avoid freezing of the liquid.

A line section for temperature-controlled guiding of a reductant for the exhaust gas post-treatment of an internal combustion engine, comprising a first line for guiding the reductant, a second line for guiding a temperature control agent, and a casing surrounding the first and second lines. The first and second lines are disposed extending adjacent to each other in the casing and guided in a coupling housing connected to the casing. Both the first and second lines are guided through the entire coupling housing while extending adjacent to each other.

A connector includes a thermally conductive body defining a passage for a fluid to flow through a duct and configured with an electric heating apparatus situated around the passage. A clip is situated around a portion of the body including one or more snap-in receptacles situated peripherally with respect to the body and configured to fit an electric connection of the electric heating apparatus.

A connection unit having a connector and at least one fluid line that is connected to the connector, wherein the connector has at least two connection ends and a connector section that connects the connection ends to one another. A fluid line end of a fluid line engages with at least one connection end of the connector. At least one compensation element is connected to the fluid line in the area of the fluid line end of the fluid line, the compensation element being supportable on at least one support stop via at least one spring element. Due to a pressure increase in the connector section, the compensation element is movable against the restoring force of the spring element in the direction of the support stop, with an increase in the internal volume of the connector section.
