摘要:
A control valve unit for a liquid circuit of an internal combustion engine, includes a valve housing (1) having at least one inlet opening (2) or outlet opening (2′) and at least two outlet openings (31, 32, 33) or inlet openings (31′, 32′, 33′) and at least two closing elements (41, 42, 43) actuated by a control device (22). The closing elements selectively open or close an associated outlet or inlet opening. The closing elements may be continuously adjusted between maximum open and closed positions. The control device (22) includes at least one displaceable or rotatable cam (6) and includes at least two cam tracks (71, 72, 73), each of which is assigned to a closing element (41, 42, 43) and acts on at least one driving pin (11) that is in contact with said closing element (41, 42, 43). The cams (6) are adjusted by an actuator (8).

摘要:
A self-cooling exhaust gas injection device making it possible to inject heated gases, for example recycled exhaust gases from an internal combustion engine, into the air intake distributor of this engine, characterized in that it comprises a return pipe for the exhaust gases (1) which extends in the distributor (2) to the downstream end thereof in the direction of the transfer of the recycled gasses and is equipped in this area with a series of outlet orifices (4) positioned so as to uniformly distribute these gases between each of the cylinders of the engine.
摘要:
An air intake tract arrangement for an internal combustion engine includes an exhaust gas inlet device arranged at the inlet side of a charge air cooler and configured to direct injected EGR exhaust gas substantially in a direction towards an inlet of said charge air cooler, thereby enabling the use of plastic intake tract components.

摘要:
A device for exhaust gas recirculation for a combustion engine is provided that includes an exhaust gas pipe configured to conduct exhaust gas and a channel configured to conduct air to the combustion engine. The exhaust gas pipe terminates in the channel, wherein the exhaust gas pipe, in an area of insertion in the channel exhaust, is in thermal exchange with a coolant from a coolant circuit.

摘要:
A vehicle seat comprising a back and a seat proper which includes a rigid frame supported by a raising mechanism for moving the seat upwards or downwards, the raising mechanism being controlled by an actuator which comprises a tube provided with a nut and a screw which co-operates with the nut, the screw being provided with a free end situated inside the tube, the raising mechanism further comprising an elastically-deformable member for assisting the motor of the actuator. The elastically-deformable member is housed inside the tube of the actuator between the free end of the screw and a support element secured to the actuator tube.
