Abstract: An air outlet device has a supporting structure suitable for communicating, in use, with an air ventilation system, and an outlet member that is configured so as to supply an air flow along an outlet axis and is coupled to the supporting structure so as to rotate by 180° about a joint axis orthogonal to the outlet axis, to assume two opposite configurations. The outlet member comprises a plurality of deflecting walls defining a plurality of air ducts, which are arranged about the outlet axis and distributed axially in sequence. The deflecting walls are shaped and/or positioned so as to guide the air in the air ducts in directions having a radial component. At least one of the deflecting walls has a series of through-holes made in positions that are spaced apart about the outlet axis.

Abstract: Described herein is a unit for conversion of thermal energy including: —a first heat-exchange unit defining a first flow path for a first thermovector fluid; and—a second heat-exchange unit defining a second flow path for a second thermovector fluid. The second flow path is obtained by a plurality of cartridge elements each including at least one element made of thermoelectric material. The second heat-exchange unit includes a first manifold element and a second manifold element, each including a connection interface to said plurality of cartridge elements, which is configured for providing a hydraulic connection with inlet orifices and outlet orifices of the cartridge elements, and an electrical connection to first electrodes and second electrodes of said plurality of cartridge elements electrically connected to the elements made of thermoelectric material.

Abstract: A system for distributing air in the passenger compartment of a vehicle, e.g. of a motor vehicle, comprises at least one outlet for the outflow of air in the passenger compartment which can be activated placing a hand at a short distance therefrom without touching it.

Abstract: A system for air distribution in the passenger compartment of a vehicle, for example a motor vehicle, includes at least one outlet for outflow of air into the passenger compartment, which can be activated by putting one's hand at a short distance therefrom without touching it. Associated to the air outlet is an optical sensor, which is set at distance from the air outlet and is optically connected to a window adjacent to the air outlet.

Abstract: A sealing ring is set between the engine block of an internal-combustion engine and a cylinder head fixed to the engine block, within a seat set concentrically around a cylinder of the engine. The sealing ring has a composite structure, with an external hollow annular body made of superelastic material, and an internal hollow annular body including a shape-memory alloy.

Abstract: A flow of air coming out of a louver facing the internal space of the passenger compartment of a vehicle is oriented, exploiting the Coanda effect, in an area adjacent to a first surface of the passenger compartment or in an area adjacent to a second surface of the passenger compartment.

Abstract: A vehicle seat comprises at least one passage for a heating or conditioning air flow and a flow deviating device associated to the seat to control the flow of air through such passage. The flow deviating device comprises at least one Coanda effect deviating device. In the case of application to the front seat of a car, the passage internal to the seat for the ventilation air flow has an upstream end communicating with an air supplying duct, and a downstream end communicating with a discharge duct whose outlet opens at the rear of the seat, to ventilate the rear part of the car passenger compartment. Said passage inside the seat is formed on the surface of the seat padding in the area of contact with the user's body, immediately below the cover of the padding. The discharge duct is arranged such that the flow of air through the passage carries out a flushing action of the area of contact with the user's body and is not forced to flow substantially through the cover.

Abstract: A motor vehicle air conditioning system including a Coanda effect air distributor device and mixing means which allow to vary the temperature of the air available to the different outlet conduits of the distributor device for the same setting of the means for regulating the temperature of the system. In this way, for a same setting of the temperature regulating means, the air conveyed to the outlets situated at the base of the windshield is at a higher temperature than the air conveyed to the other outlets and in particular to those adjacent to the floor of the motor vehicle passenger compartment. Preferably, a third, still lower temperature level is available to the outlets situated in the front part of the dashboard of the motor vehicle in the direction of the motor vehicle occupants.

Abstract: An electrical energy generator device comprising an array of micro-fans each associated to a respective dynamo-electric generator by means of a respective connecting shaft, further comprises, for at least some of the micro-fans (3), a lug element (6) associated to the respective connecting shaft (4) which mechanically co-operates at each revolution with a piezoelectric element (7), for the production of additional electrical energy. In addition or instead of the aforesaid arrangement, it is possible to provide plates (10) made of piezoelectric material which vibrate in the flow of air that invests them, thereby producing electrical energy.
