Definitions
- the invention relates to a control valve for a flow of gas flowing in a gas circuit of a motor vehicle.
- motor vehicles operating with a heat engine implement a gas circuit for supplying said engine during certain phases of use of the vehicle.
- a gas circuit has an external air inlet to the vehicle, and includes an air supply circuit located in the air and an exhaust system located therein. downstream of said engine to evacuate the flue gases.
- EGR loop Exhaust Gas Recirculation
- a portion of the flue gases for reinjecting them into the supply circuit
- the engine gas supply is provided by a mixture of incident fresh air and burnt gas.
- the flow rate of the gases in these EGR loops is regulated by means of a valve coupled to a cooler, for cooling said gases during certain temporary and specific phases of use of the engine.
- These valves therefore comprise a gas inlet and two gas outlets.
- a first outlet is provided for directly conveying the burnt gases to the supply circuit located upstream of the engine, and a second outlet is designed to previously direct said burnt gases to the cooler to cool beforehand before they arrive. in said supply circuit.
- valves are equipped with a rotary shutter, pivotable between a first position for which it closes the second outlet and causes the passage of gas to the first outlet, and a second position for which it closes the first outlet and causes the passage gases to the second exit.
- the rotation of the shutter is controlled and is performed automatically from a central computing unit that sends a suitable electrical signal at the appropriate time.
- the current valves have a flap dimensioned in a somewhat limited way so that it can pivot easily in the valve, so that the flap leaves gaps of passage of the gas at the level of the duct that is supposed to close, said interstices being rather localized around this component. This results in an approximate and poorly controlled operation of the EGR loops, which may affect the operation of the gas supply flow of the engine.
- valves according to the invention implement a flap associated with a particular internal structure of said valve, said flap and said interacting structure to ensure a perfect seal of the flap in at least one of its closed positions.
- the opening and closing phases of the valve are clean, without leaving any fraction of residual gas, thus making the gas supply circuit perfectly reliable and fully effective.
- the invention relates to a valve for regulating a gas flow in an EG R loop of a gas supply stream of a vehicle engine, comprising a gas inlet, a first outlet of gas for directly conveying the gases in the supply circuit, and a second gas outlet for passing said gases through a duct passing through a cooler before injecting them into said supply circuit, said valve having a rotary flap adapted to pivoting between a first position for which it closes the second output while opening the first output, and u second position so that it closes the first output while opening the second output.
- the flap comprises a planar main body adapted to open or close the cond u it, the internal structure of the valve having a flat flange, so that the main body of the shutter comes into contact year against led it rim when led it flap is found in its second position.
- the shutter of the valve according to the invention makes it possible to open and exit the other outlet simultaneously, and vice versa.
- the valve according to the invention has thus undergone a dual arrangement, at the level of both the duct and the shutter, so that the main body of the shutter comes into plane contact with the duct, to ensure sealed opening of the second outlet, without loss of gas to the first outlet.
- the valve can flow cleanly and thus without loss, exhaust gases to the cooler of the EGR loop, before sending them into the main gas supply circuit of the engine.
- the duct forms a loop with an inlet extending the second outlet of the valve and an outlet opening at the first outlet of said valve
- the flap may have a secondary secondary body in continuity with the main body, said shutter being positioned in the valve so that it can pivot about an axis of rotation between the main body and the secondary body, the secondary body being adapted to open or close the outlet of said conduit.
- the main body and the secondary body are rigidly connected to each other.
- the main body extends in a direction perpendicular to the axis of rotation, while the secondary body extends in a direction parallel to said axis of rotation.
- the two lateral edges of the main body each have a relief, the internal structure of the valve having complementary reliefs, so that the reliefs of the main body come into bearing against the complementary reliefs of said structure to ensure sealing of the conduit.
- the lateral edges of the main body of the flap are located symmetrically on either side of the longitudinal axis of said main body. This complementarity of the rel iefs allows the shutter to ensure at its main body closure of the conduit with a maximized sealing.
- a valve according to the invention thus has a flap for sealing the duct, and a sealed opening of said duct, without loss of gas to the first outlet.
- a relief can just as easily be materialized by a hollow or a projecting element.
- the complementary reliefs are positioned at the periphery of an orifice of the internal structure of the valve.
- the complementary relief or reliefs can be obtained by machining the internal structure of the valve.
- the reliefs of the main body are represented by two elongate protuberances extending laterally along the body, which is rotated so that it rests on a section, the complementary elements being embodied by parts dug in the structure i nte rne dela va nn e.
- the essential for this configuration is that the protuberances are placed in said excavated parts, to ensure a close contact between the internal structure and the flap.
- the fact that the protuberances have a rounded shape privileges the sealing conditions by avoiding introducing angles that could be sources of gas passage.
- each protuberance and which is furthest from the secondary body is rounded, to best fit the excavated parts of the internal structure of the valve. These additional rounded portions further accentuate the sealing conditions between the flap and the entrance of the duct.
- the main body and the two protuberances are made in one piece, said protuberances corresponding to two stamped areas of the main body. This shutter configuration is the simplest and the fastest to burn. The embossing is an operation also making it possible to obtain a part having a precise geometry.
- the free end of the secondary body and which is farthest from the main body is delimited by a rectilinear flange extending parallel to the axis of rotation, said end being beveled.
- this end is gradually refined to end with a ridge.
- This bevel therefore increases the amplitude of rotation of the flap, so that it occupies a satisfactory position for which it will ensure the opening of the duct without loss of gas and ensure a tight closure of the first outlet.
- the bevel can also reduce the clearance between the end of the flap and the bar.
- the shutter is made of sheet metal.
- This material gives a certain flexibility to the flap, which can thus be deformed slightly in contact with the cond u it, in order to fully ensure its function of éta nchéotti l ors the opening or closing of said conduit.
- the valves according to the invention have the advantage of function ner neatly, both during the closing phase of the pipe and during its opening phase, by providing an improved seal by means of judicious arrangements. simple and quick to implement, and therefore inexpensive. Indeed, these arrangements consist of making small machining retouches at the entrance of the duct and to slightly modify the geometry of the shutter, so that the interaction of the shutter with the duct is optimized.
