Definitions

  • the invention relates to a fuel distribution device for supplying the cylinders of an internal combustion engine, in particular a direct injection engine and more particularly an engine powered by relatively high pressure.
  • the invention particularly relates to a new mode of realization of such a device, easy to manufacture, easy to install and low return price.
  • the fuel distributor in an internal combustion engine, with direct injection, has an elongated body, of general shape tubular, connected by an axial end to the outlet of a fuel pump and comprising, arranged along its length, several outlet sockets made at the favor of protruding bosses. These output sockets are connected to the different injectors. Other sockets are possibly provided to be connected to pressure and / or temperature sensors, a damper or a regulator.
  • the tubular, elongated body is difficult to achieve. One piece must be made heavy, which must in any case be resumed in machining.
  • Such an elongated tubular body also comprises several supports or anchoring lugs for fixing on the cylinder head.
  • the very form of such distributor and the need to fix it at several points practically means that define a specific model for each type of engine.
  • European patent application No. 0 427 977 describes a dispenser comprising an elongated and short length cavity mounted on a base comprising a pressure and / or temperature sensor. Access to cavity including the input connected to the pump and the outputs connected to the injectors, are grouped on one end of the body. These accesses communicate with the cavity by holes. Most of these holes are made at an angle and lead to the upper part of the cavity. Such dispenser is delicate and expensive to make. The thickness of the walls of the body is relatively large and the piece is heavy.
  • the invention proposes a new type of distribution device for fuel, easy to produce in large series with relatively low cost prices.
  • One of the aims of the invention is to provide a distributor space and reduced weight particularly resistant to high pressures.
  • Another object of the invention is to propose such a distributor which can have a large number of ports, for connections to the different cylinders and engine sensors, which can be arranged in numerous locations of said body.
  • Another object of the invention is to provide a dispenser whose cavity has a particularly low volume but nevertheless capable of feeding under high pressure a relatively large displacement engine, all other things being equal elsewhere.
  • the invention relates to a dispensing device fuel for supplying the cylinders of an internal combustion engine, type comprising a hollow body in the wall of which are made accesses intended to be connected, in particular, to a fuel supply source under pressure and a plurality of injectors for supplying said cylinders, said body hollow comprising a part of a cavity and a bore, in which is engaged a closure arrangement constituting a part of the internal face of said cavity, and which extends between said portion of cavity and an orifice of said body, characterized in that that the cavity is at least approximately spherical or oblong in profile, in that that said bore is shouldered, extending substantially radially between said part of cavity and said orifice of the body and comprising, separated by a shoulder, a first section, interior, communicating with said cavity part, and a second section, exterior, threaded, and in that the plugging arrangement of said bore has an inner part engaged in said first section, constituting the part of the internal face of said cavity, and
  • the cavity can be spherical, substantially spherical or profiled slightly oblong.
  • Said inner part of the closure arrangement may include a recess completing said cavity.
  • a joint can be interposed between the plugging arrangement and said drilling.
  • the spherical or almost spherical shape of the cavity is advantageous insofar as all accesses can communicate with the cavity by means of holes of which the internal terminal parts, at least, extend substantially radially. This allows you to organize access to any body locations all around the spherical cavity or practically spherical.
  • the mounting screwed between the hollow body and the arrangement of plugging makes it possible to very significantly reduce manufacturing costs for a surprisingly high pressure resistance.
  • the inner part of the closure arrangement is separate from the threaded part.
  • This part interior may include a first shoulder cooperating with that of the drilling and, in this case, the seal, mounted between said body and said part interior, not likely to be damaged when screwing said part threaded.
  • This shoulder will be referred to hereinafter as "first shoulder"
  • the seal can be housed in an annular groove made on a portion cylindrical of said inner part.
  • This joint can also be compressed between two shoulders including that of said bore.
  • the shoulder of the drilling can be chamfered to create an annular space capable of to accommodate a seal of suitable shape.
  • an at least approximately flat seal interposed between the shoulder of the bore and said first shoulder of said part interior.
  • the shoulder of said stepped hole can be chamfered to define an enlarged annular space with said first shoulder of said inner part.
  • said relatively flat seal has a annular allowance in the vicinity of its inner edge, suitable for occupying the enlarged annular space.
  • the interior portion of the closure arrangement and the threaded part can form a single piece.
  • the volume of the cavity can be relatively reduced taking into account the displacement of the motor to be supplied.
  • the volume of the cavity can be reduced to 30 cm 3 .
  • a fuel distribution device 11 for supplying the cylinders of a internal combustion engine, for example a diesel or petrol engine, piloted direct injection, under relatively high pressure.
  • the dispensing device essentially comprises a hollow body 12 in the wall of which are provided access points 14 intended to be connected, in particular, to a pressurized fuel supply source (the pump) and to a plurality of injectors respectively supplying the cylinders of the engine.
  • the different accesses are not differentiated. They are formed on a solid crown 16 in one piece with said hollow body, possibly coming from molding, forging or other technique.
  • the hollow body has a part 18 of a cavity 17 substantially spherical. Said part of cavity formed in the hollow body is here substantially larger than a hemisphere. Typically, it should constitute at least half of the cavity and, in the case of a cavity rigorously spherical, at least half a sphere.
  • Each access 14 includes a hole 19 of small internal section, substantially radial orientation and a tapped hole 20 of larger diameter emerging on the outside, here on the crown 16 and connecting to the weak hole section.
  • each small section hole 19 extends perpendicularly to the outer surface 16a of the crown, that is to say radially relative to the cavity 17 when it is spherical.
  • the hollow body also includes a stepped hole 22 extending substantially radially between said portion of cavity 16 and an orifice 24 of the hollow body.
  • This bore comprises, separated by a shoulder 26, a first inner section 28, communicating with said cavity part 17 defined in said body and a second section 29, exterior, threaded.
  • the device is completed by a plugging arrangement 30 of this stepped hole 22.
  • This arrangement closure consists of an inner part 32 engaged in said first section and one end face of which has a recess 34 supplementing said cavity, i.e. connecting with the cavity part 16 defined in said body and a threaded part 36 screwed into said second section 29.
  • At least one gasket 40 is interposed between said plugging arrangement 30 and the bore 22.
  • said inner part and said part threaded plugging arrangement 30 form a single piece.
  • the seal 40 is here a seal at least relatively flat, interposed between the shoulder 26 of the drilling and a shoulder 42 of this part, here defined between said part inner 32 and said threaded portion 36.
  • This shoulder 42 will be called “first shoulder ".
  • the inner edge of the shoulder of said shouldered drilling 22 made in the body is chamfered (chamfer 45) to define an enlarged annular space with the single part composed of said inner part 32 and said threaded part 36.
  • the seal at least relatively flat, however has an annular allowance in the vicinity of its edge interior, which is adapted to occupy this enlarged annular space.
  • the inner part 32 has a first shoulder 42 cooperating with that of the drilling (shoulder 26).
  • An O-ring 48 is housed in an annular groove 49 made on a cylindrical portion of said inner part.
  • annular groove 49a can further house an anti-extrusion ring 50, adjoining said seal 48.
  • said first section of the shouldered drilling (i.e. the non-tapped section) has another shoulder 52 cooperating with a second shoulder 54 of said part interior 32. At least one seal 48 is clamped between said first shoulder 42 and said other shoulder 52.
  • an anti-extrusion ring 50 is attached to the joint 48 and the assembly is tightened between these two shoulders.
  • the internal part 32 is further separated from the threaded part 36 and the internal edge of the shoulder of the shouldered hole is chamfered (chamfer 45 a ) to define an enlarged space, here frustoconical, with said inner part 32, in particular its shoulder 42 (previously called the first shoulder) and a seal 56 with a suitable shape (annular seal with triangular section) to occupy this frustoconical annular space.
  • the face outside of the second section has a footprint 58 adapted to receive a screwing tool.
  • the part of the cavity defined in the hollow body 12 a comprises a substantially spherical end part 70, extended by a cylindrical portion 71 (for example of the order of 12 to 20 mm long) into which the accesses 14 a .
  • This cylindrical portion is itself extended by a neck 72, the section of which gradually decreases towards the outside.
  • This neck is extended by said shouldered bore, the inner section of which comprises a cylindrical portion 73 then, a frustoconical bearing 74 widening towards the shoulder.
  • the frustoconical bearing 74 ends in the plane of the shoulder 26 a .
  • the arrangement of closure 30a includes two separate parts.
  • the cavity is closed by an inner portion 32 has engaged in the first section; it forms part of the internal face of the cavity 17 a .
  • This inner part is held in place by a threaded part 36a screwed into said second section 29 a , threaded for this purpose.
  • the inner part of the closure arrangement has the general shape of a relatively thick pellet provided with a frustoconical peripheral portion 79 which comes to bear against the frustoconical bearing surface 74 defined above.
  • the threaded part has a recess in which the inner part 32 a is embedded, which forms a sort of shutter with a conical bearing.
  • the seal is ensured by the tight contact of the frustoconical surfaces 74 and 79.
  • an additional seal relatively compressible can be interposed between the shoulder 26 a formed in the body 12 a and the face of end of the threaded part 36 a .
  • the accesses 14 a are here respectively defined in massive extensions of said body, which extensions form connection end pieces 80.
  • Each access comprises a hole of small section 19 a opening in a substantially equatorial plane of the cavity (perpendicular to the axis yy ). It opens to the outside via a conical mouthpiece 81 and the endpiece 80 has an external thread 84 at its end portion.
  • FIG. 13 one of the end pieces is shown equipped with a pressure 82. External threading can be advantageous.
