Description

MAGNETIC HP CONNECTOR
TECHNICAL FIELD
The present invention relates to a magnetic high pressure connector adapted to be arranged in a fuel injection equipment to retain metallic particles present in the flow.
BACKGROUND OF THE INVENTION
In fuel injection equipment, fuel is pressurised in a high pressure pump and is ultimately delivered to fuel injectors which spray said fuel in the cylinders of an internal combustion engine. Despite filters arranged in the equipment, some metallic particles present in the fuel flow find a way through and damage the fuel injectors. A simple and efficient device retaining said particles is necessary.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to resolve the above mentioned problems in providing a high pressure connector adapted to be inserted between the outlet of a high pressure pump and the inlet of a fuel injector of an fuel injection equipment of an internal combustion engine.
Advantageously, said high pressure connector comprises an annular magnet member defining a central opening for the fuel to flow through in use so that, metallic particles present in the fuel are trapped.
The high pressure connector further comprises a body, the annular magnetic member being arranged onto said body.
Also, an inner passage extends between the opposed openings of the body, said passage defining a slow-down chamber around which is arranged the magnet member so that, in use, the fuel flow entering said chamber slows down for the magnetic member to attract and retain more easily the metallic particles.
Also, the body comprises an upstream member fixed to a downstream member, one of said upstream or downstream members defining connection means, for complementary fixing arrangement of said connector to the pump or the injector or another component of the fuel injection equipment.
Also, the other of one of said upstream or downstream members defines a holding means for holding the connector while fixing it onto said another component of the fuel injection equipment.
Also, the upstream member has a threaded outer face defining said connection means and, the downstream member has a polygonal outer face defining said holding means.
Also, the high pressure connector further defines a narrow inlet conduit drilled in the upstream member and opening in said slow-down chamber wherein the flow section enlarges so that, in use, the flow speed decreases.
Also, the high pressure connector further comprises a chicane member arranged in said slow-down chamber so that, in use, fuel flow is forced toward the peripheral area of said chamber where in the magnetic field is stronger.
Also, said chicane member defines a cone portion which apex points to the inlet narrow conduit.
Also, the cone portion is provided with apertures through which fuel flows.
Also, said chicane member is fixed in place between the upstream member and the downstream member.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention is now described by way of example with reference to the accompanying drawings in which:
Figure 1 is a 3D view of a magnetic high pressure connector as per the invention.
Figure 2 is an axial section of the connector of figure 1.
Figures 3 and 4 are axial sections of an alternative embodiment of the connector of figure 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
In reference to the figures is described a high pressure (HP) magnetic connector 10 adapted to be inserted in the high pressure circuit of a fuel injection equipment arranged on an internal combustion engine. More precisely, such injection equipment comprises a HP pump delivering, in use, pressurised fuel to a common rail which distributes said pressurised fuel to fuel injectors, ultimately spraying the fuel in the cylinders of the engine. The connector 10 is placed on the fuel flow circuit, between the outlet of the HP pump and the inlet of an injector in order to prevent some particles present in the fuel to enter the injector.
More precisely, the HP connector 10 comprises a generally cylindrical tubular body 12 which, in consideration of the fuel flow direction indicated with arrow A, extends along a main axis X from an upstream end 14, to a downstream end 16. The body 12 itself comprises an upstream member 18 fixed to a downstream member 20. Said two complementary members may we welded together or fixed with other known means.
The body 12 defines an inner through passage 22 extending between the said ends 14, 16n said passage 22, in following the general flow direction, comprises a first upstream narrow conduit 24, a chamber 26 and a cylindrical downstream recess 28 establishing together a permanent fluid communication between the upstream end 14 and the downstream end 16.
The chamber 26 has a section that enlarges in a first conical portion 30 from the opening of the narrow conduit 24 to a large central section 32, from which, said chamber section restricts in a second conical portion 34 ending in an outlet 36 that centrally opens in the bottom face of the cylindrical downstream recess 28.
In an alternative shown on the figures, between the first 30 and the second 34 conical portions, the chamber 26 is provided with a short cylindrical central portion 38 wherein is defined said large central section 32. Said first conical portion 30 is machined in the upstream member 18 of the body and, the second conical portion 34 is provided in the downstream member 20 of the body. The parting line shown on the figures indicating the faces
Also, an annular magnet member 40 arranged on the external face of the body 12 at substantially equal distances between the upstream 14 and the downstream 16 ends surrounds said central portion 38 and the large central section 32. As it is visible on figure 2, said annular magnet member 40 is arranged in an annular external groove provided in body. To enable such arrangement, the magnetic member comprises several portions that are arranged one by one in said groove.
In use, a pressurised fuel flow enters the HP connector 10 via the narrow conduit 20 wherein said flow has an inlet speed SI then, the fuel enters the chamber 22 wherein the speed reduces down to a central speed S2 because the section enlarges and, finally, the flow exits the chamber 22 and continues in the downstream recess 24 flowing toward an injector. As an illustration, test have shown that flow having a maximum value of 150 L/hour resulting in a inlet velocity SI close to lm/s slows down to a central speed S2 of around 0.8m/s at the widest section. When entering the chamber 22 and flowing at its lowest speed, the central speed S2, metallic particles present in the fuel are attracted by the magnetic field of said annular magnet member 34 toward the lateral face of the chamber, and preferably by the largest central section 28 where said field is the strongest.
Externally, the connector 10 is designed to sealingly interconnect components of the fuel equipment. In the embodiment presented on the figures the external face of the upstream end 14 is threaded 42 for complementary tightening for instance in the outlet of the HP pump and, the downstream end 16 is externally shaped with an hexagon 44 for complementary engagement of a tightening tool, a spanner or a wrench and, the lateral face of the recess 28 is internally threaded 46 for complementary connection of the end of a HP pipe. Other connection means than threads can be utilised such as clips or flanges. Also other tools can be used requiring other complementary shapes than an hexagon such as simple flats or any type of polygons or other means.
In an alternative presented on figures 3 and 4, the connector 10 further comprises a chicane member 48 arranged within the inner through passage 22 for disrupting the fuel flow, further slowing it down and forcing an external path for enabling easier trap by the magnet member 34 of said metallic particles.
In the embodiment presented said chicane member 48 is a circular plate having a central conical portion 50 and a peripheral annular area 52. The central conical portion 50 is oriented toward the upstream end 14 so pointing against the flow direction, and the peripheral annular area 52 is tightened between the upstream 18 and downstream 20 members of the body. As shown, the central conical portion 50 extends in the largest part of the first conical portion 30 of the chamber 26 and, said central portion 50 is provided with apertures 54 opening a fluid communication between the first 30 and second 32 conical portions of the chamber. Said apertures 54 are arranged in the largest part of the cone, close to the peripheral area 52 and in use, the fuel flow entering the chamber 26 slows down because of the enlarging section of the chamber, and also because of the chicane member 48 which disturbs the flown and laterally orients it toward the largest area of the chamber 22, where the wall thickness of the connector body is the thinnest, the magnetic field being the strongest so having a maximum influence to retain the metallic particles.
