Definitions
- the present invention relates to the field of electromechanical fluid dosing valves, including gas dosing valves, in particular hot gas, that is to say whose temperature can reach more than 500 ° C, or 700 ° C, fluctuating between a low temperature such as room temperature and a high temperature.
- valve-mushroom or piston (in English "poppet") moved by a linear actuator, replacing the traditional flap valves generally used for dosing applications of hot gases.
- valve gate In a valve gate, the fluid is diverted to the valve inlet to the valve that modulates the flow rate as a function of its distance, or its opening, relative to the seat of the valve.
- a particular field of the invention is that of bypass valves arranged in the supercharging circuit of an internal combustion engine, for controlling the flow of hot gas passing through a bypass or discharge path, called "bypass" In English, to momentarily discharge the turbocharger and / or to increase the temperature in the exhaust system.
- the proposed valve has, like all valves "poppet" of the prior art, a curve "flow / position of the piston" very stiff in the opening sequence.
- the valve proposed in the prior art claims to allow a more progressive curve, close to a straight line, but does not allow to define a very gradual curve, allowing a fine metering at the opening.
- This is a real disadvantage for certain applications requiring a very gradual opening, with an "S" curve for example (on an imaginary pressure diagram depending on the opening), such as gas diversion applications for a turbocharger.
- Another disadvantage of the solutions of the prior art is that the valve forms a protrusion disrupting the fluid flow and, in some applications such as turbocharger discharge applications, disrupts the fluid mixture controlled by the valve with a fluid flowing in a main conduit.
- the invention aims to solve the aforementioned drawbacks in particular to provide a metering valve ensuring precise dosing while ensuring a good seal in the closed position.
- the invention relates to a motorized fluid metering valve comprising an inlet duct, an exhaust duct and a motor displacing a linearly movable piston between a closed position in which the distal end of said piston comes from in sealing contact with a seat of complementary shape, and an open position, said valve being configured to have a variable flow rate continuously between said closed position and said open position as a function of the axial position of said piston, said duct an inlet opening into the periphery of the exhaust duct, with a constant protrusion irrespective of the position of said piston, said protuberance not extending radially beyond the centroid of said exhaust duct characterized in that said motor is a rotary electric motor driving said piston in translation.
- This configuration makes it possible not to disturb the flow of fluid regardless of the setting position of the valve.
- said motor is a rotary electric motor driving said piston through an axis whose end opposite said piston is threaded and cooperates with a fixed nut in translation driven directly by the rotor of said electric motor.
- said inlet duct opens into the periphery of the exhaust duct, with a constant protrusion regardless of the position of said piston, said protuberance not radially exceeding the barycenter of said exhaust duct.
- said axis has an anti-rotation element which cooperates with a fixed element of the motor, said inlet duct opens radially into said exhaust duct, said inlet duct opens tangentially into said exhaust duct, said piston is actuated integrally with a drive shaft of a motor,
- said distal end of said piston comes into sealed contact with a seat of complementary shape when said piston is in the close position of said engine
- said piston has at least one sealing segment
- said piston is hollow and opening in the direction of a sealing valve forming the distal end contacting said seat in the closed position
- said piston is movable in a jacket encased in said inlet duct
- said piston having at its distal portion means for sealing with respect to said liner, in order to cool the engine of actuation of the valve
- the valve comprises a flange on which is fixed the engine and which comprises circu tion of a heat transfer fluid, the flange is hollow, said inlet duct has a hollow receiving structure to accommodate said hollow flange and in that a seal is positioned at the interface of said flange and said
- the axis of said inlet duct is disposed in a transverse plane of said exhaust duct, said inlet duct having an orifice opening tangentially to the periphery of the exhaust duct.
- the axis of said inlet duct is disposed radially in a transverse plane of said exhaust duct, said inlet duct having an orifice opening into a peripheral zone of said exhaust duct without forming protuberance at the axis of said exhaust duct.
- the invention also relates to a burnt gas recirculation valve using a fluid metering valve as described above.
- FIG. 4 an isolated exploded view of a valve according to the invention
- FIGS. 6a to 6f views from below of a valve according to the first embodiment, making it possible to appreciate the gradual opening of the shut-off orifice;
- - Figures 7a and 7b sectional views of a valve according to an embodiment called "closed push", showing different openings of the closure orifice;
- FIG. 8a and 8b sectional views of a valve according to an embodiment called “pulled closure", showing different openings of the closure orifice;
- a metering valve (8) according to the invention is positioned in a turbocharger discharge application, according to a so-called “tangent” embodiment, referring to the position of the actuating axis relative to the exhaust duct (2).
- the turbocharger comprises a turbine (9), to which is connected the metering valve (8), and a compressor (10), whose operating details are not repeated here because corresponding to a conventional architecture in a modern automobile (car or truck).
- the metering valve (8) acts on the periphery of an exhaust duct (2) of the turbine, and achieves a more or less important and adjustable discharge, a gas from a duct of entrance (1).
- the inlet duct (1) is charged with hot gas from the exhaust (12) of the internal combustion engine. It joins the turbine (9) to drive the compressor (10) of fresh air to join the intake of the internal combustion engine.
- the turbine In order to discharge the turbine, that is to say to avoid too high a rotation speed of the latter which could damage the system, or simply because we want to reduce the air compression, it it is necessary to discharge a portion of the hot gas supplied by the engine exhaust duct (12) to the exhaust duct (2) through the inlet duct (1).
- the metering valve (8) allows this function advantageously thanks to the concept proposed by the present invention, minimizing the intrusion into the exhaust duct (2), far from the barycenter of the latter, and allowing a fine adjustment and ensuring a good seal of the valve.
- This metering valve (8) comprises in particular a motor (1 1) moving a piston (3) obstructing an orifice (13) located at the periphery of the exhaust duct (2).
- the engine is positioned along its axis of operation, which is oriented perpendicular to the exhaust duct. This position at the periphery, remote from the barycentre (7) of the exhaust duct (2), ie away from the center of said duct (2), makes it possible to minimize the intrusion of the metering valve (8) into the mechanical flow of gases expelled by said exhaust pipe (2), and this, regardless of the actual metering position, as shown through various positions of the piston (3) more or less obstructing the orifice (13) by Figures 6a to 6f.
- the metering valve (8) is easily fixed to the inlet duct (1) by, for example, several screws (14), as shown in Figure 2 in a view exploded.
- the concept of valve is flexible and allows to position the electrical connector (18) on several sides, as shown in Figures 3a and 3b.
- the metering valve (8) has, as can be appreciated in FIG. 4 in an exploded view, a motor (1 1), acting on a piston (3), via a screw ( 19) integral with an axis (28), said piston (3) being moved inside a liner (15) which forms the interface between the inlet duct (1) and the piston (3).
- the screw has an anti-rotation element (20). ) which cooperates with a fixed element of the motor (1 1).
- the movement of the piston can also be helical, depending on the type of motion transformation used.
- FIG. 5a A second embodiment, called “radial”, is shown in Figures 5a and 5b, referring to the actuation direction relative to the exhaust duct (2).
- the engine is positioned along its axis of operation, which is oriented perpendicular to the exhaust duct.
- FIG. 5b These sectional views, which show the exhaust duct (2), the inlet duct (1) - in part - and the motor (1 1), also make it possible to appreciate the interior of said engine (1 1). which comprises a wound stator part (21) and a rotor (22) connected to a nut (23) fixed in translation.
- the rotor (22) causes the linear displacement of the screw (19) and therefore the piston (3) via the nut (23).
- the piston can therefore go from an open position, as in FIG. 5a, where the discharge of the turbocharger is maximum, to a closed position, as in FIG. 5b, where the discharge is not allowed by the total obstruction of the air duct.
- inlet (2) by the piston (3) which bears on the seat (
- seals (24), O-ring type or more generally ring-like rings, on the piston (3) are placed seals (24), O-ring type or more generally ring-like rings, on the piston (3).
- the number of these segments is not limiting and may vary.
- two segments can be used.
- FIGS. 5a and 5b corresponds to a mode called "push closure” in the sense that the motor (1 1) pushes the piston (3) to obstruct the orifice (13).
- FIGS. 7a and 7b represent a so-called "pulling closed” mode, in the sense that the motor (1 1) pulls on the piston (3) to obstruct the orifice (13).
- the choice of one or the other of the closing modes, as well as the choice of the tangent or radial orientation of the metering valve (8) can be dictated by reasons of clutter or achievements that are not described here.
- each of them makes it possible to act on the periphery of the exhaust duct (2) without hindering the dynamics of the fluid flowing in said duct (2) and this, whatever the closed position of said duct d entry (1).
- the embodiments of Figures 1a, 1b and 2 form a protuberance (25) minimum in the exhaust duct (2), while the embodiments of Figures 5a and 5b, for example, have a protuberance (25). ) slightly larger, without however hinder the main volume of the exhaust duct (2), away from the center of gravity (7) of said duct (2).
- FIGS. 8a and 8b The configuration shown in FIGS. 8a and 8b, called “pulled closure", has a hollow piston (3) extended by a valve (26) which comes, in the closed position (FIG. 8b), to sit against a seat (FIG. 27), integral with the liner (15).
- This liner (15) therefore has several advantages: absorbing the positioning tolerances between the inlet duct (1) and the metering valve (8), sealing the motor (1 1) using the seals ( 24), ensure the valve seat (27) (26), ensure an adjustment of the geometry of the window regardless of the surface resulting from the intersection of the two inlet ducts (1) and exhaust (2).
- Said cooling principle is therefore implemented with the flange (16) on the one hand which corresponds to a first hollow portion, which is housed on the host structure (29) of the inlet duct (1). ).
- This reception structure (29) is also hollow and a seal (30) is at the interface between this reception structure (29) and the flange (16).
- the coolant, coming and draining through the channels (17) therefore circulates in the hollow flange (16) and the receiving structure (29) also hollow.
- Figure 9 shows an alternative embodiment in said "tangent closed pull" mode in which the sleeve (15) is removed to minimize the number of parts.
- the seal is made directly between the inlet duct (1) and the piston (3).
- a metering valve (8) according to the invention are to achieve a precise continuous dosing, that is to say a partial obstruction controlled finely by the motor (1 1) via the piston ( 3), while ensuring a very good seal by the fact that the piston (3) comes completely and hermetically close the orifice (13).
