Definitions

connection 1 in a detail section.
the leadership section 2 is inserted into the manifold 3 and points to the Foot end 9 of the guide section 2 has a groove 16 into which a sealing ring 17 with a support ring 1 is used.
the Sealing ring 17 seals the guide section 2 from the Manifold 3 from. 3 are two different, slightly different embodiments of the Invention shown. It's on the left Foot end 9 on the manifold 3 and can thus for example a hold-down force in the axial direction transfer.
