Definitions
- Tubular pipe element comprising a rigid longitudinal part and a flexible longitudinal part in one piece-
- the present invention relates to a tubular pipe element comprising a rigid longitudinal part and a flexible longitudinal part.
- Such elements are known, for example, forming tubular elements for joining two thermoplastic pipes or a thermoplastic pipe to a nipple.
- One . such an element is intended, for example, to be installed in the fuel supply circuit of a motor vehicle in order to connect the teat of the tank to the pipe connected to the fuel injection system in the combustion chambers of the engine.
- the pipe element ensuring the junction of the thermoplastic pipe to the nipple of the reservoir must make a tight junction, resistant to tearing and relatively flexible in order to avoid that the forces and the vibrations to which the junction during vehicle operation does not cause leaks or even rupture of the junction.
- the assembly rates are high and the connection of the pipe to the nipple must therefore be carried out quickly without requiring delicate tooling.
- the pipe thus equipped can then be mounted on a vehicle on the assembly line and be connected to the nipple of the tank or of another element of the vehicle. This operation is carried out manually by an operator who threads the free end of the flexible sleeve onto the reservoir teat and tightens the latter on the teat using a clamp.
- the junction thus produced satisfactorily meets the above-mentioned requirements.
- the structure of the junction thus produced is complex and requires a relatively large number of parts (four parts: a rigid end piece, a flexible sleeve and two clamps). This involves expensive assembly operations and complicates inventory management.
- the minimum length of the junction corresponds substantially to the length of the flexible sleeve, that is to say to the sum of the length of the reservoir teat, the length of the teat of the nozzle and the distance separating the teat from the reservoir from the teat from the nozzle.
- This length makes it difficult to install the junction in vehicles in which the space available for the components is increasingly reduced.
- the junction is relatively heavy, which goes against the current trend encountered in the automobile where manufacturers seek to reduce the weight of vehicles in order to limit their fuel consumption.
- a pipe element having a longitudinal axis along which a rigid part and a flexible tubular part extend consecutively and in one piece, the rigid part comprising an end having a substantially radial connection surface.
- the rigid part comprising an end having a substantially radial connection surface.
- the means for defining an additional connection surface allow the reinforcement of the connection between the rigid part and the flexible part both with tearing forces parallel to the longitudinal axis and with transverse bending forces, the resistance to these efforts being in particular improved by the part of the additional contact surface extending substantially parallel to the longitudinal axis of the pipe element.
- the pipe element is furthermore of simple structure, compact and relatively light.
- the pipe element can also be made of bi-material injection so that it is inexpensive.
- the means for defining the additional connection surface comprise a ring coaxial with the longitudinal axis of the element and at least partially embedded in the end portion of the flexible part, the ring having a free edge possibly having a step projecting radially in the extreme portion of the flexible part.
- the rigid part thus has a simple structure and the connection between the rigid part and the flexible part is particularly resistant to transverse forces.
- the means for defining an additional connection surface comprise lamellae extending substantially parallel to the longitudinal axis of the pipe element, the lamellae being embedded in the end portion of the flexible part and reinforcing in a radial direction said flexible part.
- the blades then make it possible to increase the resistance of the flexible part to the pressure of the fluid circulating in the circuit in which the pipe element is implanted while retaining flexibility sufficient of the flexible part.
- the pipe element forms a tubular element for joining a thermoplastic pipe to a nipple
- the rigid part comprising a male portion provided with external steps to be introduced into the pipe and a shoulder integral with said end of the rigid part having opposite the male portion, a surface forming the radial surface for connection to the flexible part, the flexible part being formed of a flexible sleeve intended to receive the teat on a side opposite to the rigid part .
- the weight of the junction produced in this way is also limited.
- the length of the junction then corresponds to the length of the nipple to which is added the distance separating the nipple from the rigid part of the tubular junction element.
- the junction therefore has a relatively short length.
- the flexible sleeve has externally at least one raised mark for the positioning of a clamp, the mark being for example a groove or an annular bead.
- the positioning mark allows the operator responsible for mounting the flexible sleeve on the nipple to precisely place the clamp on the portion of the sleeve extending around the nipple.
- FIG. 1 is a longitudinal half-section view of a pipe element forming a tubular element ⁇ junction of a pipe to a nipple, according to a first embodiment of the invention

- FIG. 3 is a view similar to FIG. 1 of a tubular junction element according to a third embodiment
- FIG. 4 is an end view of the rigid part of the tubular junction element according to the third embodiment
- FIG. 5 is a view in longitudinal section of the rigid part according to this third embodiment.
- FIG. 6 and 7 are elevation views, with cutaway, of a tubular junction element according to alternative embodiments, the flexible sleeve being provided internally with a diaphragm
- - Figure 8 is a view similar to the figure 1 of a pipe element according to a fourth embodiment, the pipe element connecting two pipes of thermoplastic material to one another,
- FIGS. 9 and 10 are views similar to Figure 1 of alternative embodiments of one of the rigid parts of the pipe element according to the fourth embodiment.
- the pipe element according to the first three embodiments of the invention forms a tubular junction element generally designated at 1, intended to allow the connection of a pipe C of thermoplastic material to a teat T also made of thermoplastic material and comprising, in a manner known per se, a tubular cylindrical part Tl having a free end provided with an external bead T2.
- L a pipe C and the teat T are represented in Figure 1 by double broken lines.
- the tubular junction element 1 has a longitudinal axis 2 along which extend a rigid part 3 and a flexible sleeve 4 coaxial with the rigid part 3 and in one piece with it.
- the rigid part 3 is tubular and comprises a male portion 5 externally having annular steps 6 of the fir tree type.
- the male portion is intended to be introduced into the pipe C.
- the rigid part 3 is here shown straight but could of course be bent.
- One end 7 of the rigid part 3 opposite the end by which the male portion 5 is intended to be introduced into the pipe C forms a shoulder.
- the shoulder 7 has, opposite the male portion 5, a radial surface 8 cooperating closely with an end portion 11 of the flexible sleeve 4 to form a radial connection surface of the rigid part 3 to the flexible sleeve 4.
- the rigid part 3 also comprises, at the radial connection surface 8, means 9 for defining an additional surface 10 cooperating closely with the end portion 11 of the flexible sleeve 4 to form an additional connection surface. At least part of the additional connection surface 10 extends parallel to the longitudinal axis 2.
- the flexible sleeve 4 is intended to receive the teat T on the side opposite to the end portion 11 and to the rigid part 3.
- the flexible sleeve 4 is shown straight in the figures but could of course be bent.
- the tubular junction element is here produced by a bi-material injection process.
- the rigid part 3 is for example made of polyamide modified for the implementation of this process and the flexible sleeve is made of elastomer such than a carboxylated nitrile rubber (XNBR) so as to form a chemical bond between the polyamide of the rigid part 3 and the ela ⁇ tomer of the flexible sleeve 4 at the radial bonding surface 8 and the additional bonding surface 10.
- XNBR carboxylated nitrile rubber
- tubular junction element and more particularly means for defining the additional connection surface 10 will now be described in relation to FIGS. 1 to 3.
- FPM fluorocarbon rubber
- HNBR hydrogenated nitrile rubber
- the additional connection surface 10 is defined by the surface of a ring 9 extending projecting from the radial connection surface 8.
- the ring 9 has a central axis corresponding to the longitudinal axis 2 and here has a dimension of 5 mm, parallel to the central axis.
- the crown 9 is embedded in the material constituting the end portion 11 of the flexible sleeve 4.
- a groove 12 extends externally around the flexible sleeve 4. The groove 12 is produced during the injection of the flexible sleeve 4.
- the free end T2 of the teat T extends away from the free edge of the crown 9 so that the junction retains some flexibility.
- the groove 12 extends at the level of the cylindrical part Tl of the teat.
- a clamp S shown before attachment in Figure 1 in double phantom, disposed in the groove 12, then extends in an ideal position to ensure effective securing of the flexible sleeve 4 on the teat T.
- the means for defining the additional connection surface 10 are formed of a ring 9, of central axis corresponding to the longitudinal axis 2, partially embedded in the material forming the end portion 11 of the flexible sleeve 4 so that the additional connection surface 10 is formed by the external surface of the crown 9.
- the crown 9 has a free edge 13 forming an external step projecting radially in the end portion 11. This step strengthens the connection of the rigid part 3 to the flexible sleeve 4 by forming an obstacle opposing the tearing of the rigid part 3 of the sleeve 4. A mechanical connection is thus formed between the rigid part 3 and the flexible sleeve 4.
- the additional connecting surface 10 is formed by the surface envelope of lamellae 9 parallel to the longitudinal axis 2 and embedded in the material constituting the end portion 11 of the flexible sleeve 4.
- the lamellae reinforce transversely the end portion 11 of the flexible sleeve 4.
- the flange T2 extends away from the free end of the strips. The strips thus make it possible to increase the resistance of the end portion 11 to the pressure of the fluid circulating in the circuit in which the tubular junction element is implanted and to adapt it to the pressure / temperature properties of this fluid.
- the flexible sleeve 4 is provided internally with a diaphragm shown at 14 in FIGS. 6 and 7.
- the diaphragm 14 extends transversely in the flexible sleeve 4 and is here produced in one piece with the flexible sleeve during the injection of the latter.
- the diaphragm 14 is produced in XNBR (or in another rubber such as those mentioned above) to be deformable between a state of rest (shown in FIGS. 6 and 7) in which the diaphragm 14 closes the flexible sleeve 4 and a state of deformation in which the diaphragm 14 delimits an orifice.
- the diaphragm 14 extends adjacent to the rigid part 3 so that once the junction element 1 is connected to the circuit, the diaphragm is brought into its deformation state by the fluid circulating in the sleeve 4 in direction E and in its rest state as soon as the fluid circulates in the opposite direction, the diaphragm then closing off the flexible sleeve to form a non-return valve.
- the diaphragm 14 extends from the side of the flexible sleeve 4 opposite the rigid part 3 so that, during the introduction of the teat T into the flexible sleeve 4, the teat deforms the diaphragm 14 and opens the conduit of the sleeve, the deformation possibly going beyond the elastic limit of the diaphragm 14.
- the diaphragm performs a function sealing the sleeve to prevent particles from entering the pipe before connecting it to the nipple. This function is advantageous in particular in the case where the tubular junction element 1 is intended to be installed in the fuel supply circuit of a vehicle, such particles running the risk of clogging the injectors of the fuel circuit.
- the sleeve 4 can also have an internal relief forming a step, preferably made in one piece with the sleeve, constituting an obstacle opposing the tearing of the teat from the sleeve.
- the sleeve 4 may further include an inner annular lip serving as a lip seal and strengthening the tightness of the junction.
- the pipe element according to the fourth embodiment is intended to allow the connection to one another of two pipes of thermoplastic material (pipes C in the figure 8, C and C in Figure 9, C and C "in Figure 10).
- the pipe element 1 has a longitudinal axis 2, a rigid part 3 comprising a male portion 5 and a shoulder 7 having a radial surface 8 for connection to an end portion il of a flexible part formed of a sleeve 4, and means 9, here a crown, delimiting an additional connection surface 10, a part of which extends parallel to the longitudinal axis 2.
- the pipe element 1 comprises a second rigid part secured to a second end portion 11 of the sleeve 4 extending opposite to the first end portion 11 mentioned above.
- the second rigid part is here made in one piece with the sleeve 4 and the first rigid part 3 according to the method mentioned above.
- the second rigid part is referenced 3 and is identical to that previously described.
- the second rigid part bears the reference 3 'and includes a circular groove 16' which extends on an end face 15 'of the rigid part 3' and is centered on the longitudinal axis 2.
- the groove 16 ' has transverse dimensions corresponding to those of line C so that line C can be received in groove 16' and be welded therein by rotation. Other forms suitable for rotary welding can be used.
- the rigid part 3 ′ has an end 7 ′ opposite the end face 15 ′ and which has a radial connection surface 8 ′ to the end portion 11 concerned of the sleeve 4.
- the crown 9 ' is embedded in the end portion 11 concerned of the sleeve 4 and defines an additional connection surface 10' to the end portion 11 concerned.
- the second rigid part bears the reference 3 "and includes snap-on means of known type intended to cooperate with a step C ".
- the rigid part 3 “comprises an end 7" having a radial surface 8 "for connection to the end portion 11 concerned of the sleeve 4.
- a ring 9 "extends from the radial surface 8" parallel to the longitudinal axis 2.
- the ring 9 is embedded in the end portion 11 concerned and defines an additional connecting surface 10" of which a part extends parallel to the longitudinal axis 2.
