A device for controlling a flow rate and expanding a fluid in a fluid circuit. The device is formed with an enclosure and a valve element arranged inside the enclosure. The valve element which is arranged movably in a linear movement in the direction of a longitudinal axis relative to the enclosure has a sealing surface and a control area formed at a first end face of the valve element and arranged adjacent to the sealing surface in the axial direction. The sealing surface is formed as a lateral surface of a straight circular cylinder with a constant outer diameter. An outer diameter of a surface of the control area corresponds to the outer diameter of the sealing surface. The control area has throughflow apertures and at least one control aperture. The valve element in the control area is formed with a substantially hollow circular cylindrical-shaped wall.

Device for controlling a flow rate and expanding a fluid in a fluid circuit and method for operating the device

An exhaust gas cooler comprises at least one exhaust gas pipe for exhaust gas being cooled and is characterized in that at least one gap is provided between the wall of the exhaust gas pipe and laterally adjacent components at the inlet of at least one exhaust gas pipe in the direction of extension of at least one wall perpendicular to the flow direction of the exhaust gas.

Exhaust gas cooler and exhaust gas recirculation system with an exhaust gas cooler

A coiling heat exchanger, characterized by a heat exchanger spiral consisting of a liquid shield with fins, whereby neighboring coils of the spiral of the liquid shield are spaced apart from one another by the fins and connected to one another in a heat exchanging manner and that the liquid shield is perfused by liquid, whereby gas flows between the neighboring coils of the spiral of the liquid shield along the coiling axis.

Rolled fin spiral EGR cooler

An engine exhaust gas circuit includes a primary circuit in fluid communication with an intake of an engine and an outlet of the engine. The primary circuit conveys a gas from the outlet of the engine to the inlet of the engine. The primary circuit including a valve body having a rotary flap rotatably disposed in the valve body. A bypass circuit extends from a branch point intermediate the outlet of the engine and the valve body to the valve body.

Multifunctional rotary valve module

A device of a system for air ducting of an internal combustion engine in a motor vehicle with a turbocharger arranged between an exhaust gas line and an intake line. The device includes a high pressure flow pathway with a valve branching from the exhaust gas line between the internal combustion engine and a turbine side of the turbocharger, a low pressure flow pathway with a valve branching in the flow direction of the exhaust gas downstream from the turbine side of the turbocharger, and an exhaust gas heat exchanger. A first flow pathway with a valve and a second flow pathway with a valve merge into a mouth region with a third flow pathway. At least one section of the high pressure flow pathway, the low pressure flow pathway, the flow pathways, and the exhaust gas heat exchanger are integrated inside a housing formed as a continuous compact unit.

High and low pressure EGR with a common valve housing

A device for the recycling of exhaust gas of an internal combustion engine in a motor vehicle. The device comprises an exhaust gas heat exchanger constructed with a first housing element with an inlet and an outlet for the exhaust gas and at least one inlet and at least one outlet for a coolant, and a compressor which is constructed with a second housing element with an inlet and an outlet for the exhaust gas. The first housing element of the exhaust gas heat exchanger and the second housing element of the compressor are constructed as a housing connected to a cohesive, compact component so that the exhaust gas heat exchanger and the compressor are arranged inside the housing.
