摘要:
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.

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.

摘要:
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.

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:
Described herein is a valve for fluids, liquids or dusts, which can be used to particular advantage for controlling openings for passage of cooling air in refrigerating apparatuses or the like. The valve comprises a diaphragm open/close element having a central part and a peripheral edge connected, respectively, to a central support and to a peripheral support. Said supports are axially displaceable 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 an axial direction of said first and second supports is controlled by shape-memory means, including at least one shape-memory wire, which extends at least in part along the periphery of the diaphragm and is activated by electrical supply means. The heating of the wire is exploited to remove any possible formation of ice or frost that might tend to prevent correct movement of the diaphragm.
