Abstract: A system for controlling the temperature of a charge air stream flowing through an air-cooled intercooler of a turbocharged internal combustion engine, with a fan for producing a cooling air stream acting on the intercooler and with an actuation unit for controlling the flow of cooling air as a function of charge pressure present at the intercooler.

Abstract: A connection arrangement for a connection to an intake side of an oil pump in a housing (1) of a vehicle transmission is proposed, in which a separate intake connection element (4, 4?) with integrated intake booster is provided.

Abstract: A fan assembly for an agricultural tractor includes a rotatable fan mechanically driven by a drive shaft coupled to an internal combustion engine. A fan shroud encloses the outer periphery of the fan and is mechanically connected to the engine. A bearing is mounted on the drive shaft and supports the fan shroud so that the drive shaft is rotatable with respect to the fan shroud. The bearing prevents radial and axial movement of the fan shroud relative to the drive shaft. A fan housing is connected to a radiator which is connected to the engine. The fan housing is coupled to an end of the fan shroud by a friction coupler which prevents rotation of the fan shroud.

Abstract: A control valve (12) comprising a valve housing (13) having two inflow openings (6, 7) and one outflow opening (8), in whose inner valve chamber (14), which is filled with a pressurized medium, a switching mechanism (20, 32) is displaceably arranged between two switching positions, while the switching mechanism (20, 32) respectively opens one of the inflow openings of the valve housing (13) and respectively closes the other inflow opening in both switching positions. In order to shorten the switching time in a control valve of this kind, it is provided that the switching mechanism (20, 32) comprises at least two separate sealing mechanisms (17, 18; 24, 25), which are movably arranged along respectively allocated circular arc sections approximately coaxially to the inflow openings (6, 7) in order to open and close the two openings (6, 7).

Abstract: A cooling system for a motor vehicle includes an engine cooling circuit in which an engine cooling circuit coolant pump pumps the coolant through at least one engine cooling system and an engine cooling circuit heat exchanger. The cooling system also includes a separate supercharger air cooling circuit in which a supercharger air cooling circuit coolant pump pumps the coolant through at least one supercharger air cooler and a supercharger air cooling circuit heat exchanger. The two cooling circuits are connected with a common expansion tank via ventilation lines which connect each cooling circuit with an upper portion of the expansion tank.
