DETAILED DESCRIPTION

[0043] The following detailed description is merely illustrative in nature and is not intended to limit the embodiments of the subject matter or the application and uses of such embodiments. As used herein, the word exemplary means serving as an example, instance, or illustration. Any implementation described herein as exemplary is not necessarily to be construed as preferred or advantageous over other implementations. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.

[0044] FIG. 1 shows a detail of a hydraulic component system 2 in section. By way of example, it shows a hydraulic component 4 which is produced at least in part by a generative stratified construction method. Particularly the region which is visible in FIG. 1 is produced by a method of this kind, and therefore all the components depicted form a single integral part. In the foreground, the figure shows a line end 6, which is embodied as a pipe section and has a receiving section 8.

[0045] The receiving section 8 is designed to receive a hydraulic line 10 and to enter into a high-pressure-resistant joint therewith. For this purpose, the receiving section 8 has an opening 12, which is of conical design in an end region 14, with the result that the cross section of the opening 12 tapers into the line end 6 from a first cross section A to a second cross section B. Directly adjoining this there is a cylindrical section 16, the inside diameter of which is matched to an outside diameter of the hydraulic line 10. An end of the cylindrical region 16 which faces away from the conical region 14 has an annular boundary surface 18, which is configured to correspond to an annular end face 20 of the hydraulic line 10. The hydraulic line 10 can therefore be inserted into the receiving section 8 through the conical region 14, wherein the insertion depth is limited by the annular boundary surface 18.

[0046] A sealing means in the form of a cutting ring 22 is arranged on the hydraulic line 10 and has a first end region 24 shaped in the form of a sleeve. This end region has an end edge 26 and a second end region 28 facing away therefrom. The outside diameter of the first end region 24 increases slightly over a relatively short distance in the direction of the second end region 28 and then remains constant. Consequently, the end edge 26 is a kind of cutting edge. The surface gradient over the conical first end region 24 corresponds to the surface gradient of the conically shaped region of the opening 12. As a result, the cutting ring 22 can give rise to a uniform force which causes surface pressure in the radial direction, i.e. a force acting in the direction of a center line 32, when it is moved in the direction of the opening 12.

[0047] The second end region 28 has a first axial contact surface 30. By way of example, this is likewise of conical configuration. The outside diameter of the first axial contact surface 30 increases over a relatively short distance in the direction of the end edge 26 and then remains constant over a certain region.

[0048] A fastening element 34 has an engagement region 36, which surrounds the receiving section 8 in the illustration shown. Arranged opposite is a clamping region 38, which, on an inner side facing the engagement region 36, has a second axial contact surface 40 designed to correspond to the first axial contact surface 30. Both axial contact surfaces 30 and 40 are in surface contact with one another, and the fastening element 34 completely surrounds the cutting ring 22.

[0049] On an outer circumferential surface 42, the receiving section 8 has first engagement means 44, which are arranged by means of second engagement means 46 on an inner side of the engagement region 36. These can be embodied as threads, for example. The fastening element 34 can be firmly connected to the receiving section 8 by engagement of the engagement means 44 and 46, with the result that the cutting ring 22 is pressed into the opening 12. As a consequence, there is a build-up of material on the hydraulic line 10, which brings about sealing resistant to high pressure.

[0050] The receiving section has a first annular stop surface 48, with which a correspondingly shaped second annular stop surface 50 of the fastening element 34 comes into surface contact. The first annular stop surface 48 is arranged in a transitional region 52 of the receiving section 8 which performs a continuous taper or expansion of the outside diameter of the line end 6. A force acting locally in the axial direction can thereby be introduced very effectively into the line end 6 without causing notch effects.

[0051] FIG. 2 depicts a hydraulic subassembly 54 with a number of hydraulic components 4, which are all equipped with a receiving section 8 explained above in order to implement an advantageous weight- and space-saving connection with hydraulic lines.

[0052] FIG. 3 shows an aircraft 56 which has at least one hydraulic component system 2 of this kind. The use of a hydraulic component system according to the disclosure to save weight and reduce production costs is suitable precisely in an aircraft.

[0053] For the sake of completeness, it should be noted that having does not exclude any other elements or steps and a or an does not exclude a multiplicity. It should furthermore be noted that features which have been described with reference to one of the above embodiment examples can also be used in combination with other features of other embodiment examples described above. Reference signs in the claims should not be regarded as restrictive.

[0054] While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or embodiments described herein are not intended to limit the scope, applicability, or configuration of the claimed subject matter in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing the described embodiment or embodiments. It should be understood that various changes can be made in the function and arrangement of elements without departing from the scope defined by the claims, which includes known equivalents and foreseeable equivalents at the time of filing this patent application.
