Definitions
- the present invention relates to a valve, in particular for a heat engine.
- the invention applies in particular when the heat engine is used for the propulsion of a vehicle, for example a motor vehicle. It can be an engine whose fuel is gasoline or diesel.
- the valve can be integrated in the air circuit of the engine.
- the term "thermal engine air circuit” designates the circuit between the intake inlet and the exhaust outlet of the engine.
- the valve can be arranged in the intake circuit, the exhaust circuit, or a recirculation loop through which the exhaust gases fed back to the inlet (EGR in English) pass.
- a flap mounted movably in the body between an open position and a closed position in which it must close the duct
- the body 102 has a joint plane P coming into contact with a joint plane P 'of the flap 105 when the flap is in the closed position to close the duct formed in the body 102. Because of the rigid nature contacts between the flap and the body, it is found that the jamming of the flap 105 against the wall of the body 102 is avoided when the distance Dv, measured between the center of the shaft 107 for pivoting the flap 105 in the body 102 and the joint plane P 'of the flap 105 is less than or equal to the distance De, measured between the center of the housing 108 of the body 102 in which the shaft 107 is received and the joint plane P of the body 102.
- This dimensional constraint must also be increased, to take into account the inaccuracies on the dimensions of the different parts of the valve during the manufacture thereof. Because of this increase, relatively large empty sections can exist between the body and the flap when the flap is in the closed position, these empty sections, also called “sections of leakage ", which may cause leakage greater than can be tolerated when the flap is in the closed position.
- the radial displacement tends to move the shaft away from one of the walls of the duct, so that in the closed position, leakage sections of relatively large size appear between the flap and the duct wall, thus affecting the duct. sealing the shutter in the closed position.
- the radial displacement may be any radius.
- the compensation of any differences between distances De and Dv above may be accompanied by a displacement of the shaft having the effect of increasing the leakage sections existing between the shutter and the body of the valve when the flap is in the closed position.
- the invention responds to this need with the aid of a valve, particularly for a heat engine, comprising:
- a body in which are formed: a housing in which is disposed at least one bearing, and a conduit adapted to be traversed by a fluid, and
- a drive member configured to move the shaft so that the flap pivots between:
- a closed position in which it comes into contact with the body by a first contact area of the flap located on a first side of the shaft and by a second contact zone of the flap located on a second side of the shaft opposite said first side, the bearing being configured to allow radial displacement of the shaft in the bearing when the flap is moved from the open position to the closed position, and
- the drive member being configured to guide said radial displacement of the shaft in a predetermined direction.
- the drive member is a drive wheel of the shaft, configured to guide said radial displacement of the shaft in the direction
- the drive member is a drive wheel of a wheel integral with the shaft.
- the valve comprises an actuator flap, said actuator comprising an electric motor whose torque is transmitted to the shaft to move the flap at least through the drive member.
- the drive wheel being a part already present in the assembly consisting of an actuator and a gear train.
- the position of the drive wheel which meshes directly with the wheel secured to the shaft may be chosen relative to this integral wheel so that the direction of the tangential force transmitted to the shaft is such as to guide the radial displacement. of the tree in the predetermined direction.
- This position can be combined with the direction of rotation of the drive wheel to close the flap to provide the direction of the tangential force in a direction to guide the radial displacement of the shaft in the predetermined direction.
- the body may have a body joint plane contacting the first and second contact zone of the flap when the flap is in the closed position and the first and second contact zone of the flap may belong to a flap joint plane .
- each contact zone of the shutter then forming with the joint plane of the body a plane contact when the shutter is in the closed position.
- the shutter can then be self-centering, because the contacts between the shutter and the body are effected in one and the same plane when the shutter is in the closed position and a radial clearance exists in the bearing or bearings.
- the contacts between the flap and the body can allow the immobilization of the shaft perpendicular to the single joint plane, without the shaft being in contact with the bearings.
- the component comprises:
- a first part having a first surface, a portion of which defines the first contact zone when the flap is in the closed position
- the first surface and the second surface being partially in contact with each other and being coplanar, the first portion having a length measured along the axis of the upper shaft; that of the second part, and the guidance in the predefined direction to prevent the first part of the flap away from the area of the body coming into contact with the second contact zone.
- the first and second contact areas belong in this example to opposite surfaces of the shutter while being in the same plane.
- the drive member contributes to imposing a predefined direction to the radial displacement.
- This predefined direction makes it possible to avoid that, in the closed position, too large leakage sections exist because of the distance of the first part of the shutter from the zone of the body coming into contact with the second contact zone. distance being likely to be caused by the displacement of the tree through play in the bearing or bearings.
- the flap being according to this example formed by two parts of different length, the relative lengths of the first and second parts that there is a portion of the duct in the joint plane of the body which is not closed by the body , nor by the shutter although the latter is in the closed position, thus forming a leakage section.
- the predefined direction can even bring the first part of the body part door closer to the second contact area.
- the valve can be arranged to define an angle, measured between:
- Such an angle can be used to orient the resulting tangential force transmitted to the shaft so that it is likely to guide the radial displacement of the shaft in the predetermined direction.
- the angle can be chosen so that its value is substantially equal to 110 °.
- the radial guide of the shutter according to the predefined direction can then have two beneficial effects: the one mentioned above in connection with the respect of dimensional constraints and that of reducing the leakage sections in the closed position.
- the first and second parts may each be a separate part, said parts being rigidly coupled together to form the shutter.
- Each of these parts is for example a plate.
- Said parts are in particular rigidly coupled together at the joint plane of the flap.
- the portion of the duct in which the flap moves can be formed in two parts of the body rigidly coupled to each other at the joint plane of the body.
- a part of the joint plane of the body may be defined by a second surface of one of these body parts which then comes into contact with the part of the second surface of the second part of the shutter forming the second contact zone when the shutter is in the closed position while another part of the joint plane of the body may be defined by the first surface of another part of the body which then comes into contact with the part of the first surface of the first part of the shutter forming the first contact zone when the flap is in the closed position.
- the valve may be a valve arranged in the intake circuit of the engine, in the exhaust circuit of the engine, or in an exhaust gas recirculation loop allowing the latter to be reinjected at the intake of the engine.
- This recirculation loop can be "low pressure” or "high pressure”.
- the valve is in particular a so-called "two-way" valve.
- the valve may be a so-called "three-way” valve.
- the valve can then be placed at the inlet of the recirculation loop, that is to say at the location of the exhaust circuit where the recirculation loop originates.
- the so-called "three-way” valve may alternatively be disposed at the outlet of the recirculation loop, that is to say at the location of the intake circuit where the exhaust gases are reinjected at the inlet.
- the valve is advantageously devoid of flexible element interposed between the flap and the body when the flap is in the closed position.
- Flexible is used here as opposed to “rigid”, the body and the shutter being then rigid.
- Such a flexible element is for example a seal.
- the flap and the shaft may be connected by a support extending along at least a portion of the shaft.
- the valve thus has a shaft offset relative to the flap, unlike the valves in which the shaft and the flap are arranged in the same planes.
- the shaft and the flap can be arranged in the same planes.
- the distance between the center of the housing and the joint plane of the body may be greater than the distance between the center of the shaft and the joint plane of the flap.
- This dimensional constraint generally imposed, avoids jamming of the flap against the duct wall when the flap passes into the closed position.
- the clearance of the bearing is not necessary to prevent jamming of the flap against the wall of the duct.
- the second zone of contact of the flap against the body can prevent excessive displacement of the shaft in the bearing, and thus prevent too large leakage sections exist when the flap is in the closed position . This reduces the use of the radial clearance available in the or the bearings, since the movement of the shutter due to this game to avoid jamming is not necessary.
- the distance between the center of the housing and the joint plane of the body may be less than the distance between the center of the shaft and the joint plane of the flap.
- the clearance in the bearing or bearings may be sized to be greater than or equal to a predefined global imprecision rate for the flap and the part of the duct in which the flap moves, this predefined overall imprecision rate resulting in particular from the combination linear predefined unit rate of inaccuracy for each dimension of the flap and the portion of the duct in which the flap moves.
- Each predefined unit inaccuracy rate is for example set according to the experience feedback on the technique used to manufacture the corresponding part of the valve.
- the flap may have a rectangular section in section and the first contact zone and the second contact zone may be located at opposite ends of the flap.
- the flap may have a section in the form of a half-moon whose diameter is extended by a rectangle and the first contact zone may be located on the circle of the half moon while the second contact zone is borne by the side of the rectangle opposite the side of the rectangle coinciding with the diameter of the half-moon.
