Description

BRIEF DESCRIPTION OF THE FIGURES

[0026] Further features, details and advantages of the disclosure emerge from the text of the claims and from the following description of illustrative embodiments with reference to the drawings, wherein:

[0027] FIG. 1 shows a lateral sectional view of a connector according to the disclosure,

[0028] FIG. 2 shows a top view of the connector in FIG. 1,

[0029] FIG. 3 shows a perspective side view of a further embodiment of a connector according to the disclosure.

DETAILED DESCRIPTION

[0030] FIG. 1 shows a connector 1 according to the disclosure, comprising a housing 2. The housing 2 has a first end 3 and a second end 4, between which a first duct 5 for a first fluid is configured. A second duct 6 for a second fluid is arranged at least partially within the first duct 5 and exits coaxially through the second end 4. The housing 2 has an outlet portion 7 having an outlet opening 8, through which the second duct 6 exits the housing 2. The outlet portion 7 with the outlet opening 8 is arranged in a wall 9 of the first duct 5.

[0031] Through the outlet opening 8 in the outlet portion 7, the second duct 6 for a second fluid is introduced into the first duct 5. A line-in-line system is thereby formed. The fluid systems of the first and second fluid are here configured separate from one another. The arrangement of the first and second duct 5, 6 in the connector is realized such that they are completely fluid-tight and can be flowed through.

[0032] The first and second fluid can be both different fluids and the same fluid. The connector 1 can be used for fluid such as, for instance, liquids, solutions and gases.

[0033] The second duct 6 connects a third end 10 and a fourth end 11 to one other. The ends 3, 4, 10, 11 serve for the connection of the connector to corresponding fluid lines or further connecting elements. It is therefore provided, in this embodiment, that the ends 3, 4, 10, 11 respectively have a suitable connection geometry.

[0034] In FIG. 1, the second end 4 and the fourth end 11 are configured, as connecting branches 12, 13, respectively with a spike profile 14. This enables a hose to be easily slipped onto the appropriate connecting branch 12, 13. The second duct 6 here reaches so far out of the second end 4 of the first duct 5 that the fourth end 11, which is configured as a connecting branch 13, is arranged fully outside the second end. A hose which conducts the second fluid can thereby be easily connected. A second hose can subsequently be slipped onto the connecting branch 12 of the second end, so that the hose for the second fluid is disposed within the hose for the first fluid. The connecting branch 12 of the second end 4 here has a greater diameter than the second duct 6 and the fourth end 11.

[0035] In this embodiment, the second duct 6 is arranged such that it is radially centered, at least in the region of the second end 4. As a result, the second duct 6 can be evenly flowed around by the first fluid.

[0036] As an alternative connection geometry, a circumferential protuberance 15 is suitable, as is shown in FIG. 1 for the third end 10. The protuberance 15 can be brought into connection with a further connecting element, for instance a plug connector.

[0037] A further alternative connection geometry is constituted by a receiving chamber 16 having locking elements 17, as is shown in FIG. 1 for the first end 3. Into the receiving chamber 16 a connecting element can be introduced, for instance with a protuberance. The locking elements then engage behind the connecting element and in this way prevent the connecting element from sliding out of the receiving chamber.

[0038] Between the first duct 5 and the second duct 6 a web 18 is additionally provided, which connects the two ducts 5, 6 to one other and thus stabilizes the second duct 6 within the first duct 5.

[0039] The connector 1 can be designed such that the first duct 5 has a 90-degree curvature. The second duct 6 can then have a substantially elongated course, without curvature.

[0040] FIG. 2 shows a top view of the connector 1 shown in FIG. 1.

[0041] FIG. 3 shows another embodiment of a connector 1 according to the disclosure. Therein, the first duct 5 is of elongated configuration, without curvature. By contrast, the second duct 6 has a curvature which is disposed within the first duct 5. Further features can be identical to the embodiment in FIG. 1.

[0043] All features and advantages deriving from the claims, the description and the drawing, inclusive of design details, spatial arrangements and method steps, can be fundamental to the invention both in their own right and in a wide variety of combinations.
