Abstract: The invention relates to a valve arrangement (2) for an exhaust gas recirculation device of an internal combustion engine, especially in a motor vehicle. Said valve arrangement (2) comprises a first valve (9) which is used to control a first gas path (7) and is mobile between an open position, a closed position, and at least one intermediate position. The inventive valve arrangement (2) also comprises a second valve (10) for controlling a second gas path (8) which is separate from the first gas path (7), said second valve being mobile between an open position, a closed position and at least one intermediate position independently from the first valve (9). The valve arrangement (2) also comprises a common housing (6) which contains both valves (9, 10) and through which the two gas paths (7, 8) are guided.

Abstract: A charge air cooler for an internal combustion engine is disclosed. The charge air cooler includes at least one connecting piece for connection to at least one cooling circuit configured to conduct coolant. The charge air cooler includes at least one coolant pump for circulating the coolant. The at least one coolant pump is integrated in at least one flow path within the charge air cooler.

Abstract: A fluid conditioning module, comprising: a pump and at least one additional conditioning device, wherein the pump generates a fluid cycle of at least one fluid to be conditioned between a fluid sump, the pump and the conditioning device, and wherein the at least one fluid is substantially at rest in the fluid sump.

Abstract: The invention relates to an exhaust gas recirculation device (5) for an internal combustion engine (1), especially in a motor vehicle, said device comprising an exhaust gas recirculation line (6) and an exhaust gas cooler (7) which is built into the exhaust gas recirculation line (6) and connected to a cooling circuit (8) operating by means of a liquid coolant. The exhaust gas recirculation cooler (7) comprises a cooler housing (9) which comprises at least one exhaust gas inlet (10), an exhaust gas outlet (11), a coolant inlet (12) and a coolant outlet (13), and through which a coolant flows. In order to be able to improve the adjustment of the cooling power, the exhaust gas recirculation cooler (7) contains, in the cooler housing (9) thereof, a first cooling tube arrangement (14) and a second cooling tube arrangement (15) which enables a larger heating flow between the exhaust gas and the coolant than the first cooling tube arrangement (14).

Abstract: The invention relates to a cooling system (1) in a motor vehicle with a cooling circuit in which at least one internal combustion engine (2), one pump (3) and one cooling device (4) are arranged, wherein a short circuit line (5) which bypasses the pump (3) is provided, which connects a pressure side to an intake side of the pump (3), a valve device (6) which can be switched between at least two positions is provided in the region of the short circuit line (5), in the first position the entire coolant flow flows through the short circuit line (5) and in the second position preferably the entire coolant flow flows through the internal combustion engine (2) and not through the short circuit line (5).

Abstract: The invention relates to a valve device (2) in a flow line (1) of an internal combustion engine, in particular in a cooling or an oil circuit. Pertinent to the invention is that the valve device (2) is designed in such a manner that it exhibits, at least in an open state, no or only very minimal flow resistance.
