    DETAILED PRESENTATION OF PARTICULAR EMBODIMENTS
    In Figures 2 to 5, we can see an embodiment of an oil nozzle according to the present invention adapted to the cooling of a piston or the lubrication of an internal combustion engine chain.
    The oil nozzle 100 comprises a nozzle body 101.
    The nozzle body 101 may be made of metallic material. For example, and without limitation, the nozzle body 101 may be made of steel.
    The nozzle body 101 includes a first end 101a and a second end 101b. The first end has a contact surface 10d, and the second end has an exposed surface 101e. The contact surface 101d and the exposed surface 101e are connected by a side surface 101c.
    The side surface 101c may have symmetry of revolution.
    The nozzle body 101 comprises an axial channel 102, oriented along the axis XX 'in FIG.
    The axial channel 102 opens onto the contact surface 10d of the nozzle body 101. The intersection of the axial channel 102 with the contact surface 10d forms an opening called oil inlet 103. The contact surface 10d of the nozzle body 101 is intended to be brought into contact with a surface element of the engine block. The surface element of the engine block comprises an oil supply intended to be matched with the oil inlet 103.
    The axial channel 102 may also lead to the second end 101b.
    The nozzle body 101 also includes a lateral channel 104. The lateral channel 104 communicates with the axial channel 102, and opens on the side surface 101c. The intersection of the lateral channel 104 with the lateral surface 101c forms an opening called the oil outlet 105.
    The oil nozzle 100 also includes an orientation plate 106 (Figure 3). The orientation plate 106 comprises a first face 106a and a second face 106b interconnected by a second lateral surface 106c.
    Advantageously, the orientation plate 106 may be made of plastic, for example a filled thermoplastic material, preferably polyamide loaded with fiberglass. Plastics have the advantage of making the oil nozzle 100 lighter than the nozzles known from the state of the art. Furthermore, an orientation plate 106 made of plastic material, and more particularly of thermoplastic material, can easily be manufactured by injection / molding processes in a series of repetitive manner.
    The orientation plate 106 may be made of any material, for example a metal alloy.
    The orientation plate 106 comprises a hole 107 passing right through the orientation plate 106. More specifically, the hole 107 opens onto the first face 106a and the second face 106b.
    The hole 107 is intended to house the nozzle body 101. More particularly, the nozzle body 101 is abutted in the hole 107 against the first face 106a. The abutment is produced by abutment means. The stop means are adapted to prevent any movement of the orientation plate along the axis XX 'of the nozzle body 101 when the nozzle 100 is mounted on the block of a motor for example.
    The abutment can be obtained by a shoulder, said first shoulder 10f, of the lateral surface 101c of the nozzle body 101.
    In an advantageous embodiment shown in FIG. 4a, the first shoulder 10f of the lateral surface 101c rests against the first face 106a, so that the inner surface 108 of the hole 107 does not require any complementary shoulder.
    In another advantageous embodiment (FIG. 4b), the inner surface 108 of the hole 107 also comprises a shoulder of shape complementary to the first shoulder, said second shoulder 107a. In this arrangement, the first shoulder rests on the second shoulder so as to ensure the abutment of the nozzle body against the first face 106a.
    The abutment of the nozzle body 101 against the first face 106a is not limited to the formation of shoulders. The side surface 101c and the inner surface 108 may for example be conical.
    We will also see in the following description, and with reference to FIG. 4c, that the abutment of the nozzle body 101 against the first face 106a can be achieved by means of the holding screw 110.
    In addition, according to the invention, the contact surface 101d of the nozzle body 101 is flush with the second face 106b of the orientation plate 106.
    Still according to the invention, the orientation plate 106 and the nozzle body 101 comprise first orientation means complementary to the oil outlet 105.
    Said first complementary orientation means are intended to orient the oil outlet 105 relative to the orientation plate 106. The orientation plate 106 further comprises second orientation means for orienting said orientation plate. 106 in the engine block.
    Thus, the first complementary orientation means and the second orientation means are adapted to allow the orientation of the oil outlet 105 relative to the engine block.
    We will now describe the first complementary means of orientation.
    According to a first embodiment, the first complementary orientation means may be formed by an inner surface 108 of the non-circular hole 107 (not shown). For example, the inner surface of hole 108 may include one or more flats. In addition, the side surface section 101c of the nozzle body 101 in contact with the inner surface 108 of the hole 107 may also include one or more flats to be matched with one or more flats of the interior surface 108 of the hole. 107. Thus, the interlocking, flat (s) against flat (s) of the nozzle body 101 in the hole 107 allow the orientation of the oil outlet 105 relative to the orientation plate 106.
    According to a second alternative and / or complementary embodiment, the nozzle body 101 may comprise an injection tube 112 (FIG. 4b) sealingly connected to the oil outlet 105. Thus, the injection tube 112 includes a first end and a second end, the first end being sealingly connected to the oil outlet 105, and the second end being for directing the jet of oil when the oil nozzle is in operation. The injection tube 112 may advantageously rest on the first face 106a of the orientation plate 106. Furthermore, lateral stops are arranged on the first face 106a and on either side of the injection tube 112 so that to prevent any rotational movement of the nozzle body 101, relative to the orientation plate 106, when inserted into the hole 107. In other words, the injection tube 112 is guided by the lateral stops. The lateral stops may for example be formed by a throat for receiving the injection tube 112 (FIG. 3). Such an arrangement thus makes it possible to orient the oil outlet 105 with respect to the orientation plate 106.
    The orientation plate 106 also comprises second orientation means for orienting said plate 106 relative to the engine block. The second orientation means, illustrated in FIG. 3, may comprise, for example, a lug 109 disposed on the second face 106b of the plate 106 and intended to be inserted into a hole of the engine block (not shown).
    Alternatively, as shown in FIG. 5, the second orientation means may also comprise a flat surface formed on the lateral surface 106c of the plate 106. The orientation plate 106 may have several flats, for example 2, 3 or 4 flats so as to give said plate a square shape.
    A complementary shape is also formed on the engine block, for example flat, intended to cooperate with the flat formed on the lateral surface 106c of the orientation plate 106.
    Thus, the orientation of the orientation plate 106 with respect to the engine block, and the orientation of the oil outlet 105 with respect to said plate 106 makes it possible to obtain a precise orientation of the oil outlet 105 in the engine block.
    The first complementary orientation means and the second orientation means do not require soldering to fix the orientation of the nozzle body 101 with respect to the orientation plate 106 and with respect to the engine block.
    The nozzle 100 also comprises a retaining screw 110 opening out from the contact surface 10d of the nozzle body 101. The retaining screw 110 is intended to exert a tight seal of the contact surface 101d of the body of the nozzle 101 against the casing of the internal combustion engine, and sealingly match the oil inlet 103 of the nozzle body 101, and the oil supply of said housing.
    Advantageously, the holding screw 110 is coaxially mounted to the axial channel 102 so that it opens out of the contact surface 10d of the nozzle body 101 at the oil inlet 103. The clamping of the The engine oil feed hole holding screw keeps the oil nozzle 100 in a stable position.
    The retaining screw 110 is also adapted to allow the flow of oil from the motor feed hole to the axial channel. To this end, a groove 115 (Figure 4a) can be formed along the thread of the screw along its axis of revolution. The holding screw 110 may also be hollow, namely to include a channel formed in its volume along its axis of revolution so as to guide oil from the oil inlet to the side channel 104.
    The holding screw can pass right through the nozzle body 101 from its exposed surface 101e to its contact surface 10d.
    Alternatively to the embodiments of the abutment means illustrated in Figures 4a and 4b, we present in Figure 4c another embodiment of the abutment means. In this embodiment, the stop means comprise the screw head 110a of the holding screw 110. When the holding screw 110 clamps the contact surface 10d against, for example, the motor block, the screw head 110a of the holding screw rests against the first face 106a of the orientation plate so as to prevent any movement of the orientation plate 106 along the axis XX 'of the nozzle body 101 when the nozzle 100.
    Particularly advantageously, having the contact surface 10d flush with the second face 106b of the orientation plate 106 makes it possible to minimize the stresses exerted on said plate when the retaining screw 110 seals tightly. the contact surfacelOld of the body of the nozzle 101 against the casing of an internal combustion engine.
    Thus, the minimization of the stresses on said plate allows the use of plastics, such as thermoplastic materials filled with fiberglass. On the other hand, when using plastics for forming the orientation plate 106, the tightening of the holding screw can be adjusted so that the stress exerted on said plate 106 is less than the yield strength. of the plastic material.
    In addition, the use of a plastic orientation plate 106 has no effect on the mechanical strength and / or degradation of the function of the nozzle 100 according to the invention.
    We will now describe the assembly of the nozzle 100 of Figure 4b.
    The assembly comprises the supply of the nozzle body 101. The injection tube 112 is also then introduced into the oil outlet hole 105. The injection tube 112 / nozzle body assembly 101 is then brazed so as to fix permanently and sealing the injection tube 112 to the nozzle body 101. The brazing step is performed by techniques known to those skilled in the art and is therefore not described in the present description. The injection tube assembly 112 / nozzle body 101 is introduced into the hole 107 by the first face 106a of the orientation plate 106, and abuts against said first face 106a. The stop function is performed by the first shoulder 10f, and optionally the second shoulder 107a described above. The orientation of the oil outlet 105 relative to the orientation plate 106 is achieved by the first complementary orientation means during the insertion of the nozzle body 101 into the hole 107. The orientation of the outlet oil can, for example, be performed by the introduction of the injection tube 112 between the two lateral stops or in the groove. The injection tube 112 can be folded so as to orient the jet of oil.
    Finally, the assembly comprising the nozzle body 101, the injection tube 112 and the orientation plate 106 can then be assembled to the engine block so as to match the oil inlet 103 of the nozzle plate. orientation with an oil supply of said engine.
    During the assembly step the orientation plate 106 is oriented relative to the motor housing using the second orientation means. The lug 109 is for example inserted into a hole formed in the crankcase of the engine.
    The clamping screw 110 then steadily fixes the nozzle thus formed.
    This manufacturing process requires fewer assembly steps compared to nozzles known from the state of the art.
    Furthermore, the nozzle 100 according to the invention makes possible the use of plastics for the realization of the orientation plate 106, which reduces the production costs.
