Definitions
- the present invention relates to a device advanced air flow regulator usable in a ventilation system, air conditioning or the like, depending on the preamble of claim 1.
- the object of the present invention is to overcome these disadvantages of the known regulating device.
- Figure 1 is a schematic and cross-sectional view longitudinal of a compliant regulating device to the principles of the invention.
- Figure 2 is still a schematic view and in longitudinal section, but showing another mode of realization of this regulating device.
- Figure 3 is a view similar to the previous ones but schematically showing yet another embodiment of this device.
- Figure 4 is still a schematic view of a another embodiment of a regulating device according to this invention.
- Figure 5 is a perspective view of a device regulator according to this invention and whose structure corresponds to that shown schematically on the figure 1.
- Figure 6 is a sectional view along substantially line VI-VI of Figure 5.
- Figure 7 is a perspective view of another mode realization of regulating device according to this invention and corresponding substantially to that shown schematically in Figure 3.
- a device air flow regulator essentially comprises a body 1 provided with an inlet constituting the upstream part 2 of the body 1 and of a outlet constituting the downstream part 3 of the body, this body therefore allowing the next air passage the arrows marked F and whose flow will be automatically regulated.
- the body 1 forms a conduit which can be by example mounted in a pipe belonging to a ventilation or conditioning system of air, this pipe being marked at 4 on the Figures 1 to 4 and in Figure 7.
- the body 1 is equipped with a single flap 5 which is mounted articulated on the part upstream 2 of the body 1.
- a single flap 5 which is mounted articulated on the part upstream 2 of the body 1.
- a wall 7 secured to the body 1 and defining with flap 5 a channel 8 for the passage of air from the upstream part 2 to the downstream part 3 of the body 1, as shown by the arrows F.
- the wall 7, as clearly seen in the figures, extends in an inclined direction towards the axis of channel 8 from upstream to downstream of body 1, said axis being marked X-X 'in Figures 1 to 4.
- the wall 7 can be fixed on the body 1, as shown in the figures, or else can be mounted adjustable on this body to allow the calibration of the air flow, although this is not shown in the figures.
- the wall 7 and the articulated flap 5 define a channel 8 which is convergent, and which is always maintained converge, in the direction of air flow following the arrows F for any open position of the shutter.
- the angle of convergence marked ⁇ in Figure 1 will preferably be relatively large and that the channel converge 8 will be relatively long.
- the noise generated by the movement of the flap 5 allowing the regulation is minimum, regardless of the value and the variations of the angle ⁇ of convergence, that is to say whatever the position of the flap 5 in body 1. This means that for a flow rate fixed in a determined pressure range, regulation provided by the device according to this invention exhibits excellent acoustic behavior.
- flap 5 extends beyond the section channel 8 minimum.
- flap 5a we have identified in 5a in the figures, the extension or extension of part 5, beyond the minimum section in question, that is to say beyond from the end 7a of the wall 7.
- the extension 5a of the flap 5 which extends beyond the minimum section of channel 8 is exposed to the upstream-downstream pressure difference, i.e. the maximum pressure difference.
- the part flap 5 below the minimum section is exposed to a lesser pressure difference which is increasing along the air flow. Therefore, the couple exerted on the flap 5 is maximized, limiting the harmful effects such as friction and fluctuation of pressure.
- shutter 5 is permanently requested towards a maximum opening position of channel 8 by a spring 9.
- the upstream part 2 of the body 1 has an opening or air intake 10, so as to obtain an air pressure upstream in a pressure chamber 11 formed under the articulated flap 5, between this flap and the body 1 on which is fixed to one end of the spring 9.
- the extension or extension 5a of the flap 5 ends by a fallen edge 12 cooperating with a wall 13 of the body 1 protruding inwards, this fallen edge 12 and this wall 13 in a way delimiting the pressure chamber 11.
- the component here includes a upstream end 17 having a neck-shaped profile of nozzle and which defines with the body 1 the opening of air intake 10 communicating with the pressure chamber 11.
- the flap 5 is here articulated in 6 on the body 1 around its center of gravity so any possible influence of weight and the orientation of the flap 5 will advantageously deleted.
