  • the filler neck 12 is also cylindrical and has one compared to the inside diameter of the threaded portion 18 of the closure cover 10 has a smaller outside diameter, so that this with its threaded portion 18 on the Filler neck 12 can be attached.
  • Concentric around the cylindrical filler neck 12 is a ring section 22 arranged, the one pointing into the motor vehicle radiator 14 End face 24 ends in an inwardly curved section, which is firmly connected to the filler neck 12.
  • the outer peripheral surface of the ring portion 22 goes in turn the outer wall of the motor vehicle radiator 14 over, so that the Filler neck 12 via the ring section 22 in the motor vehicle radiator 14 is held.
  • On the inner peripheral surface of the ring section 22 is an internal thread 26 into which the Screwed cap 10 with its external thread 20 is.
  • the outer diameter is slightly smaller than the inner diameter of the filler neck 12, so that the Inner part 28 can be inserted into the filler neck 12.
  • the inner part 28 has its top in FIGS. 1 to 3 Shown insertion end a radially protruding circumferential Flange 30.
  • Near the handle portion 16 has the threaded portion 18 with a shoulder 32 on its inner peripheral surface a groove 34 in which the flange 30 is received, that the inner part 28 relative to the closure lid 10 by one Axis of symmetry S of the threaded portion 18 can be rotated can.
  • Inner part 28 is a circumferential on its outer peripheral surface Ring groove 38 formed in an O-ring 40 as a sealant is recorded.
  • the end 36 of the inner part 28 has 42 on its end face several elevations projecting in the direction of the axis of symmetry S. 44.
  • a radially inwardly projecting Ring shoulder 46 formed, on the top of several Recesses 48 are formed.
  • An insert 50 is slidable within the inner part 28 added.
  • the insert 50 has several protruding radially outwards Guide pin 52, each in one on the inner part 28 trained, in the direction of the axis of symmetry S extending guide slot 54 is guided.
  • Above the Guide pin 52 is a compression spring 56 on insert 50 pushed on, which is supported on the guide pin 52 and rests on the underside 16a of the grip section 16.
  • the Compression spring 56 tensions insert 50 into a first operating position in which the insert 50 with its guide pin 52 on a radially inwardly projecting holding shoulder 58 of the Inner part 28 rests.
  • Inserting 62 has the insert 50 several in the direction the symmetry axis S protruding elevations 64, which with the Underside 16a of the recessed portion 16 formed 66 can engage, as explained later becomes.
  • the insert 50 is near its lower end 68 Outer peripheral surface a circumferential outer groove 70 in which an annular elastic sealing membrane 72 is held is.
  • the annular sealing membrane 72 has on her Inner circumferential edge an annular inner bead 74 which in the External groove 70 is added.

This results in a relative movement of the inner part 28 to the filler neck 12 prevented. Thanks to the rotatable bearing of the inner part 28 in the cap 10, the cap 10, however, screwed further into the internal thread 26 until it is with the bottom 16a of its grip portion 16 rests on the end face of the ring section 22.
