A drive-component venting apparatus comprising: the connection device according to claim 6, wherein the connection piece, at a first axial end, is connected in a fluid-conducting manner to a ventilation component, and wherein the at least one connecting rocker and a second axial end of the connection piece are configured to form a form-fitting connection to a media conduit.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a perspective view of a transmission venting apparatus,

(2) FIG. 2 shows a first sectional illustration of the connection device,

(3) FIG. 3 shows a second sectional illustration of the connection device.

DETAILED DESCRIPTION

(4) FIG. 1 shows a perspective view of a venting apparatus having a transmission vent and having the described connection device, this consequently forming a transmission venting apparatus having a connector 1 and having a transmission vent 2. The transmission vent 2 is connected to the connector 1. The connector has the torsion ring 7, which is held on the connection piece 1 via the connecting arm 13. The torsion ring 7 is connected in the connecting region 12 to the connecting rocker 8, which has the actuation section 11 and the latching section 9. A connector 1 having two connecting rockers 8 is illustrated. If a sufficiently large actuating force is applied to the actuation section 11, then the latter moves radially inward in the direction 16, while the latching section 9 moves radially outward in the direction 17. During a movement in the direction 17, the latching section is lifted out of a latching recess (not illustrated) and, in this way, the latching connection is released without a tool.

(5) FIG. 2 shows a sectional illustration of the connection device, wherein the section extends through the two connecting rockers 8, which are thus illustrated in section. It can be seen that the two connecting rockers 8 are arranged oppositely on the connection piece 5 and are connected in the connecting region 12 to the torsion ring 7. The connection piece is substantially in the form of an annularly cylindrical tube and extends along the connecting axis 6 between the vent connection 4 (at the top in the figure) and the transmission connection 3 (at the bottom in the figure).

(6) FIG. 3 illustrates the same connection device as is illustrated FIG. 2, the section plane being rotated through 90? in this figure however, so that the section extends not through the connecting rockers, as in FIG. 2, but through the two connecting arms 13 of the connecting bridge 10. The connection device is illustrated with the same orientation in relation to the vent connection 4 (at the top) and the transmission connection 3 (at the bottom) as in FIG. 2. The torsion ring 7 is held by the two connecting arms 13 and extends radially at the outside around the connecting axis 6 and the connection piece 5. The seal section 15 is formed as a radially encircling groove in the outer surface 14 of the connection piece for the purpose of receiving a seal element.

(7) In relation to this illustration, the seal section 15 is formed completely above the latching section 9 in the direction of the connecting axis 6, this being shown in particular in FIG. 2.
