The device comprises a tubular stator intended to be fixed in a pipe, so as to be traversed, in use, by said stream of fluid, and in which there is axially mounted a rotor which has a central hub from which extends a plurality of blades and which is capable of being operated in rotation by said stream, like a turbine, at a velocity variable according to the flow rate, and at least one permanent magnet integral with the rotor, disposed eccentrically with respect to the axis of rotation of said rotor. Fixed to the hub of the rotor is a shaped support bush mounted rotatable about a fixed pin or shaft which extends, projecting in the opposite direction to the operational direction of flow of the stream, from a central support integral with the axial outlet portion of the stator. The magnet is held in a housing defined between the support bush and the rotor.

Device for measuring the flow rate of fluids

The electric fan assembly includes an electric motor composed of a rotor (11) having a fan wheel (12), and a stator (10) fitted with a card (50) supporting a printed circuit for determining operation of the motor. The stator includes a bearing (60) having two main opposite faces, a lower face and an upper face, for mounting the stator (10), defines a seat (62) for the assembly formed by the card (50) and a plurality of MOSs (54) projecting from the edges of the card, where the MOSs are coplanar to the card. The seat (62) has a depth dimensioned to receive a layer of solidifying resin covering and protecting the printed circuit and the relevant connections. The stator bearing (60) is axially crossed by channels (65) providing electric connection between the stator winding leads (30) and electric contacts (52) located on the card (50) proximate to an opening (51) obtained in the card at the channels (65). Axial fins (31) extend from the upper face of the stator bearing (60) for engaging the stator (10) axially and radially.

Electronic switching fan assembly for a vehicle

A relay for use particularly in motor vehicles has a stable ferromagnetic core, an excitation coil wound around the core, a movable assembly composed of at least one movable ferromagnetic armature, a flexible foil or leaf spring fixed at a determined point of the movable armature and a contact. The relay also includes a return spring to maintain a maximum air gap for the armature with respect to the core when the device is in a release condition. At least one closure and/or opening contact is activated by the movable armature, through its contact when it is drawn or released by the core. An intermediate support element for the flexible foil is provided on one of the elements of the movable assembly.
