REFUELLING COUPLING

摘要

The invention relates to a refuelling coupling, comprising: a) a coupling plug (S), b) in which a pipe (R) movable in the axial direction is arranged, c) a coupling socket (D) corresponding to the coupling plug (S), d) wherein in the coupled state the pipe (R) extends beyond the parting plane (T) into the coupling socket (D) such that a media opening provided in the front region of the pipe (R) aligns with the inlet opening of a media line (L) arranged in the coupling socket (D), and e) means for connecting the coupling plug (S) and coupling socket (D). According to the invention: f) the pipe (R) is insulated (1), g) a first insulating body (2) is arranged at the front end of the pipe (R), h) the coupling socket (D) has a second insulating body (6) movable in the axial direction and corresponding to the first insulating body (2), and i) the pipe (R), first insulating body (2) and second insulating body (6) are sealed in a gas-tight manner (3, 4, 7).
