Definitions
- the present invention relates to a fluid circulation valve, and more specifically to a fluid circulation valve for a motor vehicle.
- the drive member comprises at least one toothed sector.
- the toothed sector is connected in rotation to a free return wheel in rotation, relative to the body, about an axis of articulation parallel to a longitudinal axis of the control shaft.
- An electric motor rotates the return wheel which in turn rotates the toothed sector and therefore the flap via the control shaft.
- the valve also comprises at least one radial abutment defining an angular stroke of the toothed sector.
- a torsion spring connected to the toothed sector and to the body makes it possible to return the drive member to a position of equilibrium dependent on the radial stops. Through the spring is also provided an axial thrust under the toothed sector so that its vertical position is maintained during its rotation.
- FIG. 1 is an axial sectional view of an exemplary embodiment of a fluid circulation valve according to the invention, according to a first embodiment.
- control shaft 4 is connected in rotation to the shutter 5 by fasteners 14, here for example a screw-nut system, or other, which allows the shutter to rotate with the shaft between two extreme positions.
- fasteners 14 here for example a screw-nut system, or other, which allows the shutter to rotate with the shaft between two extreme positions.
- One of the fully open positions, as in FIG. 1, lets the fluid pass, and the other, not shown, blocks its passage, the shutter then being applied against the lateral wall of the duct 3.
- the valve comprises an electric motor, not shown, in particular a stepping motor.
- the electric motor meshes with a large pinion 36 of the idler wheel 30 while the toothed sector 22 meshes with a small pinion 37 of the latter.
- the actuation of the motor thus causes a rotation of the return wheel 30 which in turn causes rotation of the toothed sector 22 and therefore of the flap 5 via the control shaft 4.
- the drive member 21, the intermediate wheel 30 and / or said motor are positioned in a housing 38 of the valve closed by a cover 40.
- the valve according to the invention comprises a plate 54, in particular a metal plate, defining at least a first radial abutment 56, (FIG. 2) delimiting an angular stroke of the drive member 21. More specifically, the plate 54 is rotatably connected to the control shaft 4 and overmolded by the drive member 21. In the extreme angular positions of the valve, the radial stop 56 comes into operation. contact of a stop 200 angular visible in Figure 3. The stop stop 200 angular is thus arranged to stop the radial abutment 56.
- the drive member comprises a second radial abutment 56 'visible in FIG.
