摘要:
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.

A shape memory bistable actuator includes an element movable mounted on a fixed support structure, having an intermediate position of dead center and two end positions. Spring means tend to return the movable element towards either end positions, depending on that it is on either part with respect to the dead center position. Shape memory means are provided for causing a displacement of the movable element from either end positions, against the action of the spring means, at least until the dead center position is exceeded. After this exceeding, the activation of the shape memory means can be stopped, as the spring means provide to proceed the movable element toward the new desired working position, and to hold it in such a position, despite the shape memory means are deactivated.
摘要:
A motor-vehicle dashboard incorporating an air distribution system that includes suitable means for controlling the deviation of airflow in the various ducts (3) associated with the outlet vents (2) on the dashboard, using the Coanda effect.
摘要:
A system for the distribution of air to a row of seats in a passenger compartment of a means of transport, such as for example an aeroplane, train or bus, or in the room of a building, comprises a main duct and a series of outlets. The outlets are without valves for opening and closing, and the flow of the air through the outlets is controlled by control means associated to each outlet that exploit the Coanda effect.
摘要:
An air-mixing system comprises a fluid deflector device with analogical operation which enables continuous regulation of the distribution of a main flow coming from a main duct into two secondary ducts.
摘要:
An air-distribution device based upon the Coanda-effect comprises two mobile elements that move in synchronism and in phase opposition for distributing an air flow into two ducts.
摘要:
Controlled oscillating damper, comprising: a housing (12) provided with a cavity (14), an oscillating element (18) moving sealingly within the cavity (14), in which the housing (12) and the oscillating element (18) have respective walls defining at least one chamber (44) filled with magneto-rheological or electro-rheological damping fluid, and at least one electrically controlled excitation device (46) equipped with at least one fluid passage (52) which a fluid flow gets through during the motion of the oscillating element (18). The excitation device (46) is stationary with respect to the housing (12) and is arranged so as to divide the damping chamber (44) into two sections of variable volume (44a, 44b) communicating one with the other through the passage (52).
摘要:
An air-distribution system for the dashboard of a motor vehicle comprises a plurality of auxiliary ducts that branch off in parallel from a manifold. Associated to each auxiliary duct is an additional and independent unit for regulating the flow rate and/or the temperature of the air flow that traverses the respective auxiliary duct. Each auxiliary duct branches off into a number of terminal ducts and is provided with means for the distribution of the air to the terminal ducts, which are preferably of the type comprising means of deviation of the air by the Coanda effect.

摘要:
A fluid distribution system comprised of an inlet duct (1) and two outlet ducts (6 and 7) including deviating means for directing the inlet flow into one or the other outlet ducts (6 and 7) composed of a mobile wall (2) suitable for making the flow adhere to the walls of one duct or the other due to the Coanda effect. In a first position, the mobile wall (2) is incorporated into the side wall (3) of the inlet conduct (1) that extends into one of the two outlet ducts. From this position, the mobile wall (2) can be moved to a second position where its upstream end protrudes inside the duct to create a step-like irregularity (4) on the duct's internal surface.
