摘要： A method and a device for controlling the exhaust gas recirculation in an internal-combustion engine are described herein. The engine is provided with an air-intake system, a gas-exhaust system, and an exhaust-gas-recirculation system. A linear oxygen sensor is arranged along the air-intake system in a section traversed, in use, by the air/recirculated-exhaust-gas mixture, for measuring the oxygen concentration in the mixture itself An electronic control unit is connected to the oxygen sensor and to the exhaust-gas-recirculation system for controlling the flow rate of recirculated exhaust gases on the basis of the oxygen concentration in the mixture taken in by the engine. In particular, the oxygen sensor is a UHEGO probe.

摘要： An actuator comprises an elongated shape-memory element wound around a first element and having one first end connected to the first element and one second end connected to a second element. Heating means are provided for heating the shape-memory element in order to obtain a displacement of one of the ends thereof. The elongated shape-memory element is guided so that it can slide within a closed channel made of a material having a low coefficient of friction, for example defined by a sheath.

摘要： A valve for gases, liquids or powdery material, comprises a diaphragm shutter element having a central part and a peripheral edge connected, respectively, to a central support and to a peripheral support. Said supports can be displaced axially with respect to one another between a first relative end position and a second relative end position corresponding, respectively, to the open condition and to the closed condition of the valve, or vice versa. The relative displacement in the axial direction of said first and second supports is controlled by shape-memory means, preferably formed by a first shape-memory wire and a second shape-memory wire set on the two opposite faces of the diaphragm shutter element.

摘要： The lighting device comprises a light source and an associated hollow reflector of transparent material having an internal surface and an external surface which are close to and far away from the source respectively. The inner surface of the reflector has in cross section at least one transverse plane passing through the source a discontinuous profile forming a plurality of adjacent steps each of which has a first face through which rays originating from the source can pass and a second face essentially parallel to the rays originating from the source. The outer surface of the reflector has a profile comprising one or more arcs of curves. The reflector is constructed and positioned in such a way that in the said transverse plane most of the rays emitted by the source are reflected through the first face of the steps on its inner surface and strike its outer surface undergoing total internal reflection and after passing back through the reflector emerge from it through the second faces of the steps on its inner surface undergoing a second refraction.
