Definitions
- the invention relates to throttle bodies for fuel injection device for combustion engine internal, and more particularly relates to a body butterfly comprising a housing, in which is formed a air intake duct, and comprising a butterfly disc shape substantially circular or weakly elliptical, mounted on a median axis of rotation, transverse to the duct, and movable between an open position minimum, possibly zero, and an open position maximum for which the butterfly plane is oriented substantially parallel to the axis of the intake duct, in order to regulate the air flow admitted into the engine and the amount of fuel injected per engine cycle must be linked.
- the most commonly used throttle bodies have a thin circular disc-shaped butterfly of constant thickness, and a cylinder-shaped duct circular in the area where the butterfly pivots, the section of air passage between the butterfly and the wall of the rapidly varying duct during angular displacement initial of the butterfly from its open position minimum, especially when the latter is practically nothing.
- FR-A-2 674 573 describes a butterfly body as above defined, in which the side of the butterfly that turns upstream, from the minimum opening position, has, on its downstream face, a bulge of cross section (in a plane orthogonal to the axis of rotation) sufficiently low to allow rotation of the butterfly.
- the side of butterfly turning downstream at opening and section right of duct downstream of minimum open position said side turning downstream have, in general, shapes cooperating to give the cross section of the passage of air between them a law of variation as a function the angle of rotation whose initial slope is lower at the maximum slope of the law of variation during the opening.
- the side of the butterfly turning downstream is in the form of a thin half-disc and that the intake duct presents, from the position minimum butterfly opening, a straight section circular descending downstream, which makes a butterfly of complex shape with an intake duct to wall of complex shape.
- FR-2 663 710 describes a butterfly body as defined above, whose intake duct is present, upstream as downstream of the axis of rotation, a portion of which one half is semicircular and of constant radius, and of which the other half present, at each level along the axis of the intake duct, an elliptical cross section, the complex surface with elliptical cross section located in upstream respectively downstream of the axis of rotation being of side of the butterfly which pivots upstream respectively towards downstream, at the opening.
- FR-A-2 694 963 describes a butterfly body as above defined, and the type in which the side of the butterfly which turns upstream, respectively downstream, at from the minimum open position has a form of flat half disc, and the intake duct has a wall which present, on the side of the butterfly flat half-disc and in upstream and downstream respectively of the open position minimum of the butterfly, a scalable portion of surface complex shape cooperating with this side in a flat half-disc of the butterfly so that the passage section demarcated between increases at the start of the butterfly opening, depending on the opening angle, slower than in the case of a cylindrical conduit.
- the intake duct has a cylindrical section section right corresponding to the shape of the butterfly in the minimum open position, extending upstream and downstream of this minimum opening position, and present, in upstream and downstream of the cylindrical section and along the path followed by the upstream and downstream sections of the butterfly up to a determined opening angle of the latter, of the zones respective delimited by arcs of a circle centered on the axis of the intake duct and radii decreasing at from the cylindrical section, and thus forming two scalable surface portions of complex shape, which can be symmetrical to each other with respect to the axis of rotation, and each cooperating with one respectively, by shape of a flat half-disc, of the two halves of the butterfly.
- the disadvantages of the state butterfly bodies technique presented above resides in their cost of achievement when they are metallic and in complexity of their mold and in difficulties encountered during demolding, when these butterfly bodies are molded from a synthetic material, for example a material thermoplastic.
- the molding in material synthetic butterfly body according to FR-2 663 710 and FR-A-2 694 963 requires, due to the complex forms of wall portions of the intake duct, the use of complex cores, comprising several parts, to be able to be free from molded forms, but without being able to avoid formation of plastic burrs at the parting planes of the core. It is therefore not possible to mold such butterfly bodies to their shape directly usable, without machining or deburring finish.
- the present invention aims to provide a body butterfly responding better than those previously known to requirements of the practice, especially in that it allows obtain the required opening progressivity while can be produced by molding in synthetic material without having the disadvantages mentioned above, that is, being obtainable directly from the form definable usable, without particular difficulty of mold release or particular complexity of making the mold.
- the invention proposes a butterfly body of the type above defined and known by FR-A-2 694 963, and which is characterized in that said scalable surface portion of complex shape, which cooperates with the half-disc side dish of the butterfly which turns upstream, respectively downstream, at the opening, presents, at each level the along the axis of the intake duct and on half of the cross section of the duct on the same side of the duct axis than the flat semi-disc side of the butterfly, a section substantially in the shape of a half ellipse, half of which is small axis, perpendicular to the axis of rotation, decreases gradually to a determined opening angle of the butterfly, while upstream, respectively downstream, of this portion of scalable area and over the same half of cross section of the duct, as well as on the other half of the cross section of the duct, on the side of the butterfly which turns downstream, respectively upstream, at the opening, and up to the level along the axis of the intake duct which corresponds to the downstream edge,
- the latter in the open position minimum of the butterfly, is arranged in a section right cylindrical central circular section of the duct intake, said central section being substantially symmetrical along the axis of the intake duct, on both sides across the axis of rotation, so that the throttle, preferably slightly elliptical in shape, may apply by its edge against the wall of the conduit in this section central cylindrical, for an inclination of the butterfly by relation to a plane transverse to the axis of the duct which is about 5 °, and without risk of jamming of the butterfly.
- the sections diverging downstream or respectively converging upstream of intake ducts are advantageously frustoconical from downstream edge, respectively upstream of said central section cylindrical up to the exit, respectively the entry of the intake duct, the half angle at the top of the form frustoconical can be chosen to correspond to an angle of favorable draft.
- the clearance thus achieved in the duct facilitates mounting of a butterfly locally thickened, for example in the center, for passage or integration of an axis of rotation, or on an edge.
- the section converge, respectively divergent, from half the wall of the intake duct upstream and downstream respectively of the open position minimum of the throttle valve and on the same side of the axis of rotation as the side of the butterfly that rotates downstream, respectively upstream, at the opening is advantageously a portion of frustoconical surface converging from the entrance, respectively from the outlet, from the duct to the upstream edge, respectively downstream, from the central cylindrical section, so that the diameter of the intake duct, in the introduction plane of the butterfly defined above, always remains greater than diameter of the butterfly.
- the shoulder on one side of the butterfly advantageously has a shape substantially ellipsoidal cap of major axis substantially parallel to the axis of rotation but slightly offset downstream of the latter, and the periphery of which is connected at the edge of the butterfly side turning downstream, respectively upstream.
- the butterfly can thus be made of synthetic material, for example thermoplastic, and include a flat disc on which said shoulder is molded or attached, for example fixed by ultrasonic welding, the shoulder can, for example, be formed by a cup defining a closed space, or be molded with the butterfly by defining an open space downstream in the drove.
- the housing with its intake duct can be molded in one piece to the final shape a synthetic material, for example thermoplastic.
- the butterfly body 1 has a case 2 made by molding in a synthetic material such as a thermoplastic material and obtained in its shape final without additional machining or deburring.
- a intake duct 3, of longitudinal axis 4, is formed in the case 2.
- the axis of rotation 5 is mounted swiveling in a central section 7 of the conduit 3.
- the wall of the duct 3 is a straight cylindrical wall of circular section, which extends substantially symmetrically on either side of the axis of rotation 5, along the axis longitudinal 4 of the conduit 3.
- the conduit 3 Downstream of the downstream edge 8 of the central section 7, the conduit 3 has a downstream section divergent 9, which is frustoconical from the downstream edge 8 to the outlet 10 of conduit 3, below in FIG. 1.
- the cross section of the conduit 3 is therefore circular with a gradually increasing radius, monotonously from upstream to downstream.
- the wall of conduit 3 Upstream of the upstream edge 11 of the central section 7, the wall of conduit 3 is asymmetrical with respect to the plane diametral passing through the axis 4 of the conduit 3 and the center of the axis of rotation 5.
- the wall of conduit 3 On one half, located to the right of the axis of rotation 5 in FIG. 1, of the cross section of the conduit 3, the wall of conduit 3 is defined by a section of frustoconical surface 12, which is coaxial with axis 4 as the divergent 9 downstream, but converging from the input 13 of the conduit 3, in the upper part in FIG. 1, to the edge upstream 11 of the central cylindrical section 7.
- the wall of the conduit 3 is delimited by a evolving surface portion 14, of complex shape, extending upstream of the upstream edge 11 of the central section 7 up to a position opposite the edge of the butterfly 6 when the latter is inclined on the transverse plane, perpendicular to axis 4 of conduit 3 and passing through the center of the axis of rotation 5, of a particular angle, between about 30 ° and about 50 °, and upstream of this portion of evolutive surface 14, the wall of the conduit 3 is delimited by a section of converging surface 15, which converges from entrance 13 of conduit 3.
- half of corresponding cross section of conduit 3 has a shape substantially semi-elliptical, which evolves gradually of a semi-circular shape at the upstream edge 11 of the central section 7 to a semi-elliptical half-straight section smaller semi-minor axis at the connection between the evolving surface portion 14 and the converging surface section 15.
- the straight half-section corresponding of conduit 3 has the shape of a half-ellipse of which the semi-minor axis, perpendicular to the axis of rotation 5, gradually decreases, while its large axis remains constant and equal to the diameter of the central section cylindrical 7.
- the butterfly 6 advantageously in material of synthesis such as a thermoplastic material, is made of a disc 16 which is substantially circular or slightly elliptical, of generally constant thickness, but able have reinforcing ribs, passing through a slot diametral of the axis of rotation 5, and the side of the butterfly 6 which turns downstream, at the opening of the butterfly, that is to say, taking into account the direction of rotation of the butterfly at the opening indicated by an arrow in figure 1, half the butterfly to the right of axis 5 in this figure 1, is a flat half-disc having, on its upstream face, a shoulder 17 preferably molded from the same synthetic material that the flat disc 16, and attached and fixed, by welding with ultrasound for example on the half-disc which turns towards downstream at the opening of the butterfly 6 so as to delimit a closed space.
- This shoulder 17 is constituted by a bucket projecting upstream from conduit 3 and the periphery of which downstream is connected to the downstream edge of the half-disc of the butterfly 6 which turns downstream at the opening.
- the wall of the cup 17 which is opposite the wall of the conduit 3 a substantially the shape of an ellipsoidal cap whose major axis is parallel to the axis of rotation 5, offset by short distance downstream of this axis 5, and slightly lower to the diameter of the central section 7, and whose minor axis is chosen to give this wall of the shoulder 17 a delimiting profile, with the profile facing the wall of the duct 3, a passage section for the air admitted to the motor which increases more slowly, compared to a butterfly in flat disc rotating in a cylindrical duct, when opening the butterfly 6 from its minimum open position, in which the flat disc 16 and most of the shoulder 17 are housed in the cylindrical central section 7, in a position such that the flat disc 16 is inclined a few degrees on the plane transverse perpendicular to axis 4 passing through the center of the axis
- the half-disc bearing the shoulder 17 and turning downstream at the opening is slightly inclined downstream, while on the opposite side axis 5, the flat half-disc, without shoulder, rotating upstream at the opening of the butterfly 6, is slightly tilted upstream.
- the profile of the shoulder edge 17 is chosen to allow the rotation of the half-disc which carries it downstream, without contact with the shoulder 17 with the wall of the duct 3.
- the butterfly 6 is shown in an intermediate position between its minimum open position and its open position maximum, in which the flat disc 16 of the butterfly 6 is oriented substantially parallel to the axis 4 of the conduit 3.
- this intermediate position for which the angle opening of butterfly 6 is less than the maximum angle tilt data for surface definition scalable 14
- the flat half-disc side of the butterfly 6 which turns upstream at the opening of the butterfly cooperates, by its upstream section, with this evolving surface 14 for define, between it and the upstream edge of the butterfly 6, a air passage section (circulating from top to bottom on the figures) which increases according to the opening angle slower than in the case of a disc butterfly flat rotating in a cylindrical conduit, as long as the butterfly 6 is in the initial opening phase, in which its upstream section is moved opposite the evolving surface 14.
- FIG. 2 The variant of Figure 2 is indistinguishable from the example of FIG. 1 only by making the shoulder, which is a 17 'bucket molded in one piece with the butterfly 6 'so as to delimit, in the half butterfly pivoting downstream at opening, an open space towards downstream in the conduit 3 of the same shape as in FIG. 1, so identical references are used for identify identical parts in shape.
- Figure 3 is not distinguished Figures 1 and 2 only by the realization of the shoulder 17 ", which is solid and molded and attached to the upstream face of the half-disc 16 pivoting downstream upon opening, or possibly molded in one piece with this half of disc 16 to form the 6 "butterfly.
- the housing 2 and its conduit 3 are identical.
- the variant of FIG. 4 is symmetrical with that of Figure 3 relative to the axis of rotation 5 but the air flow always flows from top to bottom in the figure. Therefore, the shoulder 17a is on the downstream face of the half of the disc 16a of the butterfly 6a which pivots upstream at the opening, while the other half of the disc 16a, which swivels downstream at the opening, moves opposite the evolving surface 14a, downstream of the downstream edge 11a of the section circular and straight cylindrical central 7a of the conduit 3a.
- the conduit 3a In downstream of the downstream edge 11a and of the evolving surface 14a, the conduit 3a has respectively a frustoconical divergent 12a and a divergent 15a, on the corresponding halves of the straight section, which extend to exit 13a of conduit 3a.
- the conduit 3a Upstream of the upstream edge 8a of the central section 7a, the conduit 3a has a frustoconical convergent 9a from its entry 10a in the housing 2a of the butterfly body 1a.
- This variant has the same advantages as previous ones concerning ease of molding and progressiveness variation in air flow. But it can be slightly unfavorable in terms of turbulence, in certain conditions of use.
