  • the supporting housing comprises two half-shells coupled together, and the inlet opening of this housing is defined jointly by respective end portions of the two half- shells, each provided with one or more of the resilient vibration-damping formations.
  • the aforesaid end portion of the supporting housing has a first and a second resilient formation of substantially annular shape, spaced apart from each other longitudinally and interconnected by a plurality of essentially wedge-shaped formations, which are spaced apart angularly and which project outwards progressively from the inlet opening to the outlet openings of the supporting housing.
  • Figure 1 is a perspective view of an air flow temperature and humidity sensor device according to the invention.
  • Figure 2 is a partially exploded perspective view of the sensor device of Figure 1 ;
  • Figure 3 is a partial perspective view which shows, on an enlarged scale, part of a half-shell of the sensor device according to the preceding figures.

  • the upper edge of the half-shell 2b has a plurality of upwardly projecting studs 5, which engage in corresponding recessed seats 6, provided near the lower edge of the half-shell 2a, only one of these seats being shown, in broken lines, in Figures 1 and 2.
  • an inner region or chamber 7 ( Figures 2 and 3) which communicates with the exterior through an inlet opening 8 formed in a front end portion 2c of the housing 2. and also through a ring of outlet openings 9 formed in an intermediate portion 2d of the housing 2.
  • a carrying structure indicated as a whole by 10 in Figure 2.
  • This structure comprises, in particular, a circuit board 1 1 , for example a printed circuit board, which carries, adjacent to the inlet opening 8 of the housing 2, an electrical temperature sensor 12 and an electrical humidity sensor 13.
  • the humidity sensor 13 is substantially cylindrical in shape, and is connected at its base to the board 1 1 , while the temperature sensor 12 extends above the humidity sensor 13.

  • This miniature fan comprises an impeller 15, having a plurality of radial blades 16, connected to a disc 17.
  • the blades 16 of the impeller 15 extend into the proximity of the outlet openings 9 of the supporting housing 2, as can be seen in Figure 1.
  • the miniature fan 14 further comprises an electric motor 18, preferably of the brushless type, on the shaft 18a of which the impeller 15 is fixed ( Figure 2).
  • the circuit board 1 1 also carries a plurality of electrical and/or electronic components of circuits associated with the sensors 12, 13 and with the electric motor 18, together with a multi-pole electrical connector 19 ( Figures 1 and 2) conveniently located in the end portion 2e of the housing opposite to the front inlet portion 2c.
  • the electric motor 18 for driving the miniature fan 14 is fixed to a supporting plate 20 of resilient material, which is clamped between the two half-shells of the supporting housing 2.
  • the resilience of this supporting plate helps to damp the vibrations caused by the motor in use.
  • the front inlet portion 2c of the supporting housing is intended to be coupled to a tubular positioning and retaining formation 51 provided on the rear face of the panel P of the motor vehicle, around the aforementioned opening 50.
  • the edge of the tubular formation 51 facing the sensor device 1 has a plurality of angularly spaced indentations 52.
  • the front end portion 2c of the housing of the sensor 1 is provided with a set of resilient formations adapted to be inserted at least partially into the tubular formation 51 , and if necessary into the indentations 52 of the edge of the latter, to limit the transmission of vibrations from this housing 2 to the panel P during use.
  • These resilient formations are conveniently made of a resilient material, and are overmoulded on the supporting housing 2.
  • the end portion 2c of the supporting housing 2 is provided, in particular, with a first and a second resilient formation of substantially annular shape, indicated by 21 and 22, which are coaxial with the opening 8 and are spaced apart from each other longitudinally.
