Abstract: A device for regulating a through-flow and expanding a fluid in a fluid circuit, in particular a refrigerant in a refrigerant circuit of an air-conditioning system of a motor vehicle. The device has a housing and a valve element arranged in the interior of the housing as well as at least one sealing element.

Abstract: An expansion and isolation valve, specifically an electric expansion and isolation valve for operation with the coolant R744, featuring a valve body arranged in a valve body chamber, a seal seat, and a seal, which are arranged along an axial movement direction of the valve body in the expansion valve. The expansion valve is further designed such that in a closed state of the expansion valve, there is a pressure bypass to the valve body chamber, and preferentially, that a valve body diameter at the positions of the seal seat and the seal corresponds with the respective seal diameters.

Abstract: The present invention relates to a heat exchanger for exhaust gas cooling, in particular for motor vehicles. The heat exchanger includes a flow duct which is formed from heat exchange tubes being arranged in parallel to one another, and through which the exhaust gas to be cooled can flow and around which a liquid coolant can flow, and secondly includes a housing having a housing wall and tube bottoms. The housing wall and the tube bottoms delimit a flow chamber for the coolant. The heat exchange tubes being arranged so as to form a tube bundle are formed with straight sections and deflection zones, wherein the heat exchange tubes in at least two deflection zones sweep an angle of at least 90°.

Abstract: A heat exchanger is disclosed for the exhaust gas train of a motor vehicle with an exhaust gas carrying exchanger tube that is formed separately and is disposed in a closed housing formed separately, a coolant flowing through the housing and around the outer side of the exchanger tube. The housing forms at least one housing cover and one housing case, the housing case being tightly closed by the housing cover. Both ends of the exchanger tube are conducted for gas and liquid tight connection through the housing cover so that the inlet and the outlet of the exchanger tube are disposed outside of the housing.

Abstract: The invention relates to a bypass valve, particularly a two-way valve for exhaust gas flows from motor vehicles, having a valve housing and an actuating mechanism with a valve flap and two ports for fluid outlet, which are embodied as alternately sealable by the valve flap, and one port for fluid intake, characterized in that at each of the ports for fluid outlet an adapter and sealing ring is provided, arranged at least partially and fluid-tight in the valve housing, wherein the valve flap can be positioned fluid-tight on the adapter and sealing ring.

Abstract: A heat exchanger is disclosed for the exhaust gas train of a motor vehicle. The heat exchanger includes a bundle of separately formed exhaust gas carrying exchanger tubes that is disposed in a closed housing formed separately, a coolant flowing through the housing and around the outside of the exchanger tubes. A bandage is disposed on the bundle of exchanger tubes mechanically connecting a plurality of the exchanger tubes to militate against an oscillation of the exchanger tubes.

Abstract: A heat exchanger for an exhaust gas train of a motor vehicle with an exhaust gas carrying exchanger tube that is formed separately and is disposed in a closed housing formed separately, a coolant flowing through the housing and around the outer surface of the exchanger tube. The housing includes a housing portion that forms one common mechanical interface for connecting the heat exchanger to the exhaust gas train and a coolant circuit of the motor vehicle.

Abstract: A device for cooling a gas stream of a combustion engine is disclosed, the cooling accomplished by means of a cooling medium with a housing in which at least a first channel is placed for conducting the gas flow through and a second channel for conducting the cooling medium through, whereby the first and the second channel are in thermal contact with each other. The housing includes an extruded part, in which at least one channel of the first and second channel are formed.

Abstract: A heat exchanger is disclosed for the exhaust gas line of a motor vehicle including at least one exchanger tube that is formed separately and disposed in a closed housing formed separately, a coolant flowing through the housing and around the outside of the exchanger tube. An inlet and/or an outlet of the exchanger tube are located outside the housing, wherein the exchanger tube is guided through a wall of the housing at a feed-through point in a coolant- and/or exhaust gas-tight manner. Additionally, a manufacturing method for the heat exchanger and an assembly tool which can be advantageously used in the method are disclosed.
