Description
- The invention relates to a coupling arrangement for coupling an injector to a fluid supply. The coupling arrangement comprises a fuel connection which is cup-shaped having a bottom portion and a side portion. The fuel connection is fixed to a pipe of the fluid supply and communicates with the pipe through a fuel opening in the bottom portion of the fuel connection.

EP 1 255 038 B1 discloses a fuel injection system for the direct injection of fuel into at least one combustion space of an internal combustion engine. The fuel injection system has at least one fuel injection valve for each combustion space. The fuel injection valve can be inserted in each case at an injection portion into an assigned receiving board formed on a cylinder head of the internal combustion engine. - It is an object of the invention to create a coupling arrangement and a connection assembly which enable a proper flexible coupling of an injector to a fluid supply.
- The object is achieved by the features of the independent claims 1 and 7. Advantageous embodiments of the invention are given in the sub-claims.
- The invention is distinguished concerning a first aspect of the invention by a coupling arrangement for coupling an injector to a fluid supply. The coupling arrangement comprises a fuel connection, a locking element, an outer spring, an inner spring, at least one pin of the connecting element, and at least one recess which is formed in the locking element. The fuel connection is cup-shaped and has a bottom portion and a side portion. The fuel connection is fixed to a pipe of the fluid supply and communicates with the pipe through a fuel opening in the bottom portion of the fuel connection. The locking element is cup-shaped and comprises a rim, a bottom portion, and side portion. The locking element is coupled to the fuel connection. At least a part of the side portion of the locking element and of the fuel connection form an overlapping area. The inner spring is arranged in the fuel connection and is fixed to the bottom portion of the fuel connection at an axial end of the inner spring. The outer spring is arranged intermediate the pipe and the locking element. The outer spring has a larger diameter than the inner spring and the outer spring forces the locking element away from the pipe. The pin of the connecting element is arranged in the overlapping area at the fuel connection. The recess is formed in the locking element and extends from the rim of the locking element towards the bottom portion of the locking element. Further, the recess extends at least partly parallel to the bottom portion of the locking element and further extends towards the rim of the locking element to a second end of the recess of the locking element. The second end of the recess of the locking element takes in the pin of the fuel connection.
- The recess of the locking element and the pin of the fuel connection enable a fixation of the locking element to the fuel connection by a positive fit. The outer spring enables the fixation by a press fit. So, the locking element may be fixed to the fuel connection very fast and in a very simple way without the need for special tools. Further, the coupling arrangement enables a light flexible movement in a small range of the locking element relative to the fuel connection. So, the coupling arrangement enables a proper flexible coupling of the locking element to the fuel connection. If the locking element holds an injector, the coupling arrangement contributes to a proper flexible coupling of the injector to the fluid supply.
- In an advantageous embodiment of the first aspect of the invention the locking element has a bigger diameter than the fuel connection. The outer spring is circumferentially arranged around an axial section of the fuel connection.
- The invention is distinguished concerning a second aspect of the invention by the coupling arrangement for coupling the injector to the fluid supply. The coupling arrangement comprises the fuel connection, the locking element, the inner spring, the outer spring, and at least one pin of the locking element, and at least one recess of the fuel connection. The fuel connection is cup-shaped and has a rim, a bottom portion and a side portion. The fuel connection is fixed to the pipe and communicates with the pipe of the fluid supply through a fuel opening in the bottom portion of the fuel connection. The locking element is cup-shaped and comprises the bottom portion and the side portion. The locking element is coupled to the fuel connection. At least the part of the side portions of the locking element and of the fuel connection form the overlapping area. The inner spring is arranged in the fuel connection and is fixed to the bottom portion of the fuel connection at the axial end of the inner spring. The outer spring is arranged intermediate the pipe and the locking element. The outer spring has the larger diameter than the inner spring and the outer spring forces the locking element away from the pipe. The pin of the locking element is arranged in the overlapping area at the locking element. The recess of the fuel connection is formed in the fuel connection and extends from the rim of the fuel connection towards the bottom portion of the fuel connection. Further, the recess of the fuel connection extends at least partly parallel to the bottom portion of the fuel connection and further extends towards the rim of the fuel connection to the second end of the recess of the fuel connection. The second end of the recess of the fuel connection takes in the pin of the locking element. The pin of the locking element and the recess of the fuel connection enable the fixation of the locking element to the fuel connection by the press fit and the mechanical fit. This may contribute to the proper flexible coupling of the injector to the cylinder head.
- In an advantageous embodiment of the second aspect of the invention the locking element has the bigger diameter than the fuel connection and the outer spring is circumferentially arranged around the axial section of the fuel connection.
- The invention is distinguished concerning a third aspect of the invention by a connection assembly for connecting the injector to the fluid supply. The connection assembly comprises the coupling arrangement and a connection section of the injector. The connection section is radially surrounded by the locking element. The connection section protrudes into the coupling arrangement through an injector opening in the bottom portion of the locking element. The connection section has a fixation body which is fixed to the connection section of the injector and which has at least partly a larger diameter than the injector opening of the bottom portion of the locking element.
- In an advantageous embodiment of the third aspect of the invention the injector opening of the bottom portion of the locking element and at least a part of the connecting section of the injector are formed and arranged in such a way that the locking element holds the injector in its position respectively a rotation of the injector around an axis of the injector.
- The invention is explained in the following with the help of schematic drawings.
- These are as follows:
- figure 1
- a first embodiment of a connection assembly,
- figure 2
- a cut through the connection assembly according to
figure 1 , - figure 3
- a side view of a locking element,
- figure 4
- a coupling arrangement of a second embodiment of the connection assembly,
- figure 5
- a part of a fuel connection.
- Elements with the same design or function that appear in the different illustrations are identified by the same reference characters.
- A cylinder head 2 (
figure 1 ) has a recess 4. Aninjector 6 is arranged in the recess 4 of thecylinder head 2. Theinjector 6 is coupled to apipe 8 of a fluid supply by a connection assembly. The connection assembly comprises acoupling arrangement 10 and a connectingsection 10 of theinjector 6. - The
coupling arrangement 10 comprises afuel connection 12 and a lockingelement 14. - The
fuel connection 12 is cup-shaped comprising arim 11, a bottom portion and a side portion of thefuel connection 12. Thefuel connection 12 communicates with thepipe 8 through afuel opening 13 in the bottom portion of thefuel connection 12. Apin 26 of thefuel connection 12 is arranged at an outside of the side portion of thefuel connection 12 in an overlapping area which is formed by at least a part of the side portion of the lockingelement 14 and by at least a part of the side portion of thefuel connection 12. - The locking
element 14 is cup-shaped having arim 17 of the lockingelement 14, a side portion, and a bottom portion. Theinjector 6 protrudes into thecoupling arrangement 10 through aninjector opening 15 of the lockingelement 14 at the bottom portion of the lockingelement 14. Theinjector 6 has a connectingsection 20 which is radially surrounded by thecoupling arrangement 10 and, in particular, by the lockingelement 14. The connectingsection 20 has afixation body 22. Preferably, thefixation body 22 is a washer which is fixed to theinjector 6 at the inside of the washer and which has a larger outer diameter than theinjector opening 15 of the lockingelement 14. - The locking
element 14 is pressed away from thepipe 8 by anouter spring 16. Theouter spring 16 is circumferentially arranged around an axial section of thefuel connection 12 and intermediate thepipe 8 and the lockingelement 14. Aninner spring 18 is arranged in thefuel connection 12 and is fixed to the bottom portion of thefuel connection 12 at one axial end of theinner spring 18. Theinner spring 18 forces theinjector 6 away from thepipe 8 in its seat in the recess 4 of thecylinder head 2. - Preferably, the
connection section 20 of theinjector 6 and theinjector opening 15 of the lockingelement 14 are formed and arranged in such a way that theinjector 6 is held in its position according to a rotation of theinjector 6 around an axis X of theinjector 6 by theinjector opening 15 of the locking element 14 (figure 2 ). For example, a part of theinjector opening 15 has a spherical shape and an other part of theinjector opening 15 has a linear shape. Then, theinjector 6 comprises a similar shape in an corresponding area at theconnection section 20 at its outer shell. So, the rotation of theinjector 6 around its axis X is prevented by the mechanical fit between theinjector opening 15 of the lockingelement 14 and the corresponding area at theconnection section 20 of theinjector 6. - A recess 28 (
figure 3 ) of the lockingelement 40 extends from afirst end 30 of therecess 28 of the lockingelement 14 towards the bottom portion of the lockingelement 14 and then further therecess 28 of the lockingelement 14 extends at least partly parallel to the bottom portion of the lockingelement 14. Therecess 28 of the lockingelement 14 further extends from the at least partly parallel part of therecess 28 of the lockingelement 14 towards therim 13 of the lockingelement 14 to asecond end 32 of therecess 28 of the lockingelement 14. The extension of therecess 28 of the lockingelement 14 enables a mechanical fit between the lockingelement 14 and thefuel connection 12. - If the
injector 6 is assembled to the fluid supply, at first the lockingelement 14 is pre-assembled to theinjector 6 in such a way that the bottom portion of the lockingelement 14 is axially arranged between thefixation body 22 of theinjector 6 and that part of theinjector 6 which is arranged in the recess 4 of thecylinder head 2. Then, theinjector 6 is stuck into thefuel connection 12 and the lockingelement 14 is stuck onto thefuel connection 12 in such a way that thefirst end 30 of therecess 28 of the lockingelement 14 takes in thepin 26 of thefuel connection 12. Then, the lockingelement 14 is forced further towards thepipe 8 and so thepin 26 of thefuel connection 12 follows therecess 28 of the lockingelement 14. If thepin 26 of thefuel connection 12 reaches the at least partly parallel part of therecess 28 of the lockingelement 14 the lockingelement 14 has to be turned in such way that after the turn thepin 26 of the lockingelement 14 is arranged underneath thesecond end 26 of therecess 28 of the lockingelement 14, with respect tofigure 3 . Then, theouter spring 16 presses the lockingelement 14 away from thepipe 8 in such a way that thesecond end 32 of therecess 28 of the locking element is pressed against thepin 26 of thefuel connection 12. So, theouter spring 16 enables a press fit of the lockingelement 14 to thefuel connection 12. - In this way, the locking
element 14 and, respectively, theinjector 6, are fixed to thefuel connection 12 by a positive fit and by a press fit. This contributes to a proper coupling of theinjector 6 to the fluid supply in a very easy and very fast way. This contributes to low costs for manufacturing the connection assembly. - In an alternative embodiment (
figure 4 ) thefuel connection 12 has a recess 40 (figure 5 ). Further, the lockingelement 14 has apin 46 of the lockingelement 14. - The
recess 40 of thefuel connection 12 extends from therim 11 of thefuel connection 12 towards thepipe 8 and further at least partly parallel to the bottom portion of thefuel connection 12 and further towards therim 11 of thefuel connection 12 to asecond end 44 of therecess 40 of thefuel connection 12. - If the locking
element 14 is assembled onto thefuel connection 12, thepin 46 of the lockingelement 14 is introduced into therecess 40 of thefuel connection 12. Then theouter spring 16 has to be compressed in such a way that thepin 46 of the lockingelement 14 arrives in the parallel part of therecess 40 of thefuel connection 12. Then, the lockingelement 14 has to be turned around its axis X in such a way that thepin 46 of the lockingelement 40 is arranged above thesecond end 44 of the lockingelement 14, with respect tofigure 5 . Then, theouter spring 16 may force thepin 46 of the lockingelement 14 against thesecond end 44 of therecess 40 of thefuel connection 12. - Preferably, an 0-
ring seal 24 is arranged between theinjector 6 and thefuel connection 12, in order to have a proper sealing between theinjector 6 and thefuel connection 12. - The invention is not restricted by the explained embodiment. For example, the recesses of the
fuel connection 12 and of the lockingelement 14 comprise alternative shapes. Further, thefuel connection 12 and/or the lockingelement 14 may comprise one or more pins. Further, thefuel connection 12 and/or the lockingelement 14 may comprise thepin 26 and therecess 28 of thefluid connection 12 and, respectively, thepin 46 and therecess 40 of the locking element.
