Definitions

  • the present invention essentially relates to a device for controlling a throttle valve for admitting gases into an internal or external combustion engine.
  • the present invention aims to remedy these drawbacks by proposing a device for controlling a throttle valve which is of a simplified structure and which advantageously provides damping at the start of opening and closing of the butterfly.
  • Also known from document FR-A-2 528 113 is a device for controlling an intake throttle of the type described in the preamble to claim 1.
  • the subject of the invention is a device for controlling a throttle valve for admitting gases into a combustion engine and of the type in which an operating pedal is connected to the throttle valve by connection means which comprise a spring element and the part between the spring and the butterfly is connected to a damper which is mounted between two points of articulation, one of which is articulated on a part pivoting on a fixed axis, the damper being of the single-acting type and arranged so as to act only when its line of action approaches the fixed axis, characterized in that the line of action of the shock absorber passes through said fixed axis when the butterfly is in a position partial opening, and is located on one side or the other of this fixed axis when the throttle is in the large opening or closing position.
  • this device is further characterized in that the aforementioned articulation point of the damper to the workpiece is integral with a throttle control cable, while the other articulation point this shock absorber is fixed.
  • the other point of articulation of the damper is articulated on the end of a lever integral with the butterfly and the other end of which is articulated on the part by means of a link.
  • the aforementioned part has a cam shape on which the aforementioned link is articulated.
  • FIG. 1 there is shown a device for controlling a throttle valve 1 for admitting gases into a combustion engine, said throttle valve being controlled by an accelerator pedal 2 articulated at 3 on the vehicle.
  • the pedal 2 is connected to the butterfly 1 by means of an elastic element 4, for example forming a spring.
  • an elastic element 4 for example forming a spring.
  • a damper 5 of a type known per se and essentially comprising, as can be seen in Figures 1 and 3 a body 6 in which is housed a deformable membrane 7 biased by a spring 8 and comprising, as is clearly visible in FIG. 3, a restricted orifice 9 establishing permanent communication between the two chambers separated by the membrane 7.
  • the damper 5 is mounted by its ends between two articulation points 10, 11 one of which 11 is articulated on a part 12 capable of pivoting about a fixed axis 13 so that, as we understand, the line of action of the shock absorber 5 can either pass through the fixed axis 13 or be located on one side or the other of this fixed axis as a function of the pressure exerted on the pedal 2.
  • the articulation point 11 of the damper 5 to the part 12 is integral with a cable 14 for controlling the throttle 1.
  • This cable 14 is connected at 15 to the pedal 2 and at 16 to a reel 17 for controlling the butterfly valve 1, the latter being biased by a return spring shown diagrammatically at 18.
  • the spring 4 mentioned previously is here interposed on the cable 14 between point 15 and the point of articulation 11 of the damper on the part 12 and on said cable 14.
  • the other point 10 of articulation of the damper 5 is a fixed point, so that the damper can pivot around this point, just as the articulation point 13 of the part 12 is also a fixed point .
  • This part 12 is constituted by a push rod, but, for a better understanding of the invention, the following will explain how the device which has just been described works with the aid of FIG. 2.
  • the cable 14 actuable by the accelerator pedal is connected, via the spring 4, to a part 12 which, here, has the shape of a cam pivoting around the fixed axis 13.
  • the articulation point 11 of the rod 19 of the damper 5 is articulated on the part 12.
  • the other point 10 of articulation of the damper 5 is no longer a fixed point of articulation, but is articulated on the end of a lever 20 secured by its part 20a of the axis 20b throttle valve 1.
  • the butterfly 1 is controlled indirectly by a lever 20 and link 22 system allowing a reduction in the start of opening of the butterfly 1.
  • the relative position of the points of articulation 10 and 11 relative to the fixed axes 13 and 20b of the cam 12 and of the butterfly 1 respectively determines the variation in distance which occurs during the movement between the points d hinge 10 and 11.
  • the distance between the points of articulation 10 and 11 will stop decreasing, so that the opening of the butterfly will be done without delay.
  • the spring 4 can be replaced by another elastic means, for example integral with the connecting rod 22, the latter being able to be produced so as to constitute itself a spring.
