Definitions

  • the invention relates to an electromagnetic actuation device of valve (s) for internal combustion engine.
  • valves minus one per cylinder, for the admission or exhaust of gases. These valves are controlled in synchronism with the operation of the engine. Their opening or closing moment must be checked from very precise way.
  • These electromechanical type control devices for opening or valve closure include a pallet or magnetic tray cooperating with one or two electromagnets and springs.
  • the palette is moves between the two electromagnets.
  • One end of the race of the pallet corresponds to the closed position of the valve and the other end of the race corresponds to the open position. In each of the positions end, a spring is compressed and another spring is relaxed.
  • the electromagnet serves to hold the pallet in each end position while the springs help move the pallet from one end from his race to the next.
  • a particularly simple type of actuating device has been described in European Patent No. 1,174,596.
  • This device is shown on the In this known embodiment, there is provided a single electromagnet 1 to inside which is disposed a permanent magnet 5.

  • the magnetic induction created by the permanent magnet 5 holds the pallet In each of the end positions, either against the ends of the branches 8 and 9, against the ends of the branches 10 and 11.
  • a coiled coil 2 is fed around a branch of the magnetic circuit so as to create a field magnetic which opposes the effect of the magnet.
  • the compressed spring pushes the pallet 15 towards the other end position.
  • the spring 18 compressed pushes the pallet 15 towards the ends of the branches 10 and 11.
  • This actuating device is particularly simple and the Electricity consumption is low.
  • this structure has a footprint that is not easily compatible with compactness sought for the realization of engines.
  • the startup is difficult from the halfway position which corresponds to the position of balance of the springs.
  • the object of the invention is to enable the realization of a device polarized type (ie permanent magnet) reduced size and which is easily manufactured in large series.
  • the actuating device comprises two parts substantially C-shaped ferromagnets in planes different and separated by two permanent magnets whose fields are substantially parallel and in the same direction, the plans of the two ferromagnetic parts in C being parallel or forming a angle, the pallet being arranged to be able to move between ends of said branches of the two parts in C and a coil is wrapped around a branch of each C, preferably around the main branch, the windings of these two coils being in sense inverses.
  • the C magnetic parts have good rigidity, which is important for motor vehicle parts.
  • the magnet or magnets are between the parts Magnetic C, it can (or they can) extend into a larger volume important than in the known structure. It follows that the field Remanent magnet (or magnets) may be weaker. In addition, the structure can be such that the magnet can be easily replaced.
  • the structure of the actuating device is also such that the pallet is of a size and therefore of a reduced weight.
  • the C-shaped magnetic parts are produced in laminated sheets.
  • the device comprises a second magnet connecting the faces lateral to both parts.
  • the first and / or second coil is, for example, on a branch opposite to the open branch of the first or second part.
  • the magnet (or magnets) has (s) at least one substantially co-planar slice (52, 54) with slices of the two parts of the magnetic circuit.
  • the two parts of the magnetic circuit are, preferably, sheet metal flaky.
  • the pallet has two end portions of which each has the same shape and dimensions as the slices corresponding ends of the open branches of the circuit parts magnetic in C.
  • Each of the two parts of the magnetic circuit presents in a embodiment a substantially flat shape and these two planar parts, separated by one or two magnets, are substantially parallel.
  • the two parts of the magnetic circuit can be practically identical and arranged symmetrically with respect to a median plane parallel to these two parts.
  • the two full branches of each C part of the magnetic circuit are opposite each other in projection on a plane parallel to the two parts.
  • each of the two parts of the magnetic circuit has a substantially flat shape and these two flat parts are separated by one or two magnets and form between them an acute angle of way that the distance separating the ends of the open branches of the C lower than the distance between the major branches of the parts in C.
  • each of the two parts of the circuit C-shaped magnet has a substantially shaped first section plane and parallel to the corresponding section of the other part, the magnet or the magnets being disposed between these two parallel sections and a second section of form and layout such as the distance separating ends of the open branches of the C be lower than the distance separating the major branches of the two parts in C.
  • At least one face of the pallet may have at least one shoulder to which corresponds a shoulder of one end of an open branch part of the C-circuit.
  • the shoulder may extend as rectilinear or curvilinear direction.
  • the pallet may have a generally rectangular, orthogonal or circular.
  • the section of the magnet or magnets in contact with both parts of magnetic circuit is for example greater than the section of the ends two open branches of the two parts C of the magnetic circuit.
  • the magnet or magnets are (are) ferrite.
  • the invention also relates to a set of at least two devices valve actuators arranged in such a way that the coils of the two actuators are moved away from each other.
  • the invention also relates to an internal combustion engine comprising at least one actuating device of the type defined above.
  • the valve actuator shown in FIGS. 2 and 3 comprises a magnetic circuit formed of two pieces 30 and 32 each of which has the form
  • the two magnetic pieces 30 and 32 are made of laminated sheet and are identical. Each of them has a branch central coil around which is wound a coil 34, 36. These two coils have windings that generate fields magnetic in opposite directions.
  • the open branch 38 of the C spans a space 40 in which is disposed a magnetic pallet 42 for moving in this space (air gap) 40 in a direction parallel to the main branches of C.
  • the two parts 30 and 32 have flat lateral faces. They are arranged parallel to each other and, in the example, so that the four edges of the wafer are aligned. For example, the edge 44 1 of the piece 30 is aligned with the edge 44 2 of the piece 32.
  • the actuating device has two permanent magnets, respectively 46 and 48, which are identical and whose magnetizations are in the same direction.
  • Each of the magnets presents a slice in the same plane as the slice upper or lower C parts and another slice in the same plane as the outer edge of the C-pieces.
  • upper 52 of the magnet 46 is coplanar with the upper slices parts 30 and 32 and the outer vertical edge 54 of the magnet 46 is coplanar with the vertical outer edge of the C 30 and 32 pieces.
  • Both magnets 46 and 48 play a similar role in creating the magnetic field of polarization.
  • a single magnet is used (46 for example) that can be achieved by a single magnet or by several magnets magnetized in the same direction.
  • the parts magnetic circuits 30 and 32 may be made from plates relatively thin. Magnets 46 and 48 also have a thickness moderate.
  • This device is easily industrializable by making parts magnetic laminated material. We can use magnets from relatively small residual field because, compared to the magnet shown in Figure 1, they occupy a substantially larger volume. In in addition, in the structure shown in FIG. 2, the magnets are not surrounded by the coils 34 and 36 and are accessible from outside the structure. As a result, they are easily replaceable.
  • the actuator is installed in the direction shown, its bulk in the direction f 1 ( Figure 2) is low, which allows to use it in combination with another actuator of the same type for a multi-valve motor in which the distance between the valves is relatively small.
  • the structure is such that the pallet 40 has a small footprint and therefore a low mass, which minimizes the operating energy of the device.
  • An advantage of making the magnetic parts 30 and 32 in laminated sheet lies in the fact that the induction created by the coils 34 and 36 is in the plane of these sheets (as shown in Figure 2) and, consequently, the induced currents are in the perpendicular direction, that is to say they are cut by the open circuits between sheets.
  • FIG. 3 shows the rod 50 integral with the pallet 42 which cooperates with the valve stem (not shown in Figures 2 and 3).
  • the magnetic fields produced by the magnets 46 and 48 are represented by double arrows while magnetic fields produced by the coils 34 and 36 are represented by a simple arrow.
  • the magnetic flux created by the magnets is added to the pallet 40.
  • the polarization magnetic circuit created by the magnets
  • the magnetic induction B a is maximum while in the lower air gap, between the pallet 40 and the circuits C 30 and 32, the magnetic induction created by the magnets is zero.
  • the magnets 46 and 48 play a similar role in the creation of the polarization magnetic field.
  • a single magnet 46 for example
  • a single magnet 46 for example
  • the magnetic flux created by the coils 34, 36 passes through the closed gap and an air gap 52 of the order of 8 mm.
  • the induction created by coils remains weak but sufficient to allow operation.
  • part of the coil flow closes directly between the laminated magnetic circuits at magnets 46 and 48.
  • FIG. 5 shows a variant in which, as in the embodiment shown in FIGS. 2 and 3, the two magnetic circuits in C 30 1 and 32 1 are flat parts also in laminated sheet and these flat parts are in substantially parallel planes. .
  • the main branches are not close but opposite. It is the same with the coils 34 1 , 36 1 .
  • the magnets 46 1 and 48 1 have substantially the width of the open branches of the C and connect the facing faces of these C.
  • the magnet 46 1 has an upper edge 60 aligned with the upper edge 62 of the part 30 1 on the side of the open branch of C.
  • the other upper edge 64 of the magnet 46 1 is aligned with the upper edge 66 of the C side of the part 32 1 .
  • the magnet 48 1 is arranged in a similar manner to the magnet 46 1 . However, it has an opening (not shown) for passing the valve stem or the stem of the pallet 42 1 , this tail or this rod also not being shown in FIG. 5.
  • the parts magnets are farther apart, which reduces leakage magnetic field. Indeed, in the embodiment shown in FIG. there may be magnetic leakage between the parts 68 of the parts 30 and 32 which are not separated by the magnets 46 and 48.
  • FIGS. 6, 7 and 8 differs from that shown in FIGS. 2 and 3 in that the magnetic parts 30 2 and 32 2 are not parallel but form an acute angle in such a way that they are close to the side of the open branch of the C to minimize the size and therefore the mass of the pallet 42 2 .
  • the coils 76 and 78 are wound around the central part of the full branch of each C-piece.
  • the pallet 42 2 has, in the example, in plan a shape adapted to that of the ends facing the open branches of the C-shaped pieces.
  • the part 42 2 has a central portion 76 in the form of trapezoid whose non-parallel sides are the short sides of rectangles, respectively 78, 80.
  • the rectangle 78 corresponds to the facing ends 82 1 , 82 2 of the open branches of the C of the part 2 and the rectangle 80 corresponds to the corresponding ends for room 32 2 .
  • the mass of the pallet can be further reduced by optimization surfaces facing the magnetic circuits.
  • the small size of the pallet makes it possible to install the device valve actuation for engines whose spacing between valves is weak. We can also, with this realization, maximize the power of the actuating device for a given distance between valves.
  • the magnets are thick, which makes it possible to confer significant efforts to maintain the magnets in the open position of valve or in the closed valve position.
  • each circuit in C has two parts forming between them an obtuse angle, namely a first part 92 having the solid branch around which is wound the corresponding coil 94 and the beginning 96 of the branches perpendicular and, on the other hand, a portion 98 comprising the branch C open (not shown) between which the pallet 100 moves ( Figures 9 and 10).
  • the pallet 100 has a trapezoidal shape as shown in FIG. its two ends corresponding to the ends in the form of parallelograms 102 and 104 of the free ends of the open branches of C.
  • FIGS. 9 and 10 presents the same the advantages shown in Figures 6, 7 and 8. However, the Making the magnet is simpler.
  • the embodiment shown in FIG. 11 differs from that shown in FIG. 3 in that the ends 106, 108 and 110, 112 open branches of each C-shaped magnetic piece form beaks so that these ends are closer to one another than magnetic parts. Under these conditions, the pallet 114 can be of smaller dimension.
  • the pallet magnetic 116 has shoulders 118 and 120 and the ends open branches of the C pieces have shoulders correspondents.
  • the purpose of this provision is to linearize the effort attraction of the magnetic parts on the pallet 116 according to the air gap.
  • the pallet 116 has a greater thickness in its central part and smaller thicknesses at the ends thus providing four shoulders 118, 120, 118 1 , 120 1 .
  • the ends of the C-shaped magnetic parts have shoulders complementary.
  • the end 122 of one of the open branches 124 of a magnetic piece C 126 has a shoulder 128 for come next to the corresponding shoulder 118 when the pallet is attracted to the top.
  • the shoulders 118, 120 and the shoulders 118 1 and 128 1 are straight, while in the example shown in Figure 14, the shoulders 118 ', 120' are curved. It is of course also the corresponding shoulders on the ends of the magnetic parts in "C".
  • the pallet is no longer sensitive to angular offsets of this palette.
  • the shape of the pallet is not limited to that described. So, another example in which the pallet is shown in FIG. has an octagonal section. Such an octagonal palette will be moreover preferred to a rectangular pallet because with such a geometry, it can be shown that for the same mass, the forces exerted on the palette are more important than in the case of a shape pallet rectangular. We can also reduce the weight of the pallet by force of identical attraction.
  • Figures 3a, 3b, 3c and 3d illustrate arrangements for making low-remanent magnetization magnets, particularly ferrite magnets, while generating high levels of induction in the magnetic circuit and in the air gap, in order to optimize the force of attraction and to minimize the mass of the magnetic circuit.
  • the principle of the flux concentration is used which consists in conferring a section S a (FIG. 3b) of magnet greater than the section of the ferromagnetic circuits S f (FIGS. 3a, 3c and 3d) and that of the air-gaps .
  • the length of the pallet is reduced in the same proportions as the distance between the lateral faces external parts of the two magnetic parts.
  • FIG. 16 shows two control devices of the type of those described in relation to FIGS. 2 and 3, one of which, 130, is intended for order a first valve and the other, 132, is intended for order a second valve near the first.
  • These two control devices are arranged so that the plans of the parts magnetic are parallel. However, the main branches of magnetic circuits and therefore the coils are in opposite positions.
  • the distance L between the axes of the two valves, controlled by devices 130 and 132 is substantially equal to the thickness e of a device of control without taking into account the overthickness of the coils 134.
  • the thickness e is the distance separating the external faces of the two parts magnetic devices of a control device.
  • Figure 17 is a figure similar to that of Figure 16 but in the case where two control devices 136 and 138 of the type of those shown in Figure 5.
  • FIG. 18 shows two control devices 140 and 142 of the type shown in Figures 6 and 7. It can be seen that compared to Figures 16 and 17, it is possible to reduce the distance between two valves. This achievement is therefore particularly interesting for equipping a small displacement engine or to obtain significant efforts, for example in the case of actuators for the exhaust.
