Abstract (en)
[origin: WO2004090917A1] The bushing comprises a first annular gasket (9) with convex quadrangular section, inserted in the annular groove (10) which, together with the annular protecting edge (11), protects the gasket from the sunlight and prevents excessive radial expansion of the compressed gasket (9) towards the outside. In this way deterioration of the gaskets (7) and (9) is reduced. The bushing also comprises a second annular gasket (7) tightly packed between the ceramic body (1) and the outer second body (5) which defines a slanting surface (6) and a second annular protecting edge (8), which serve to protect the gasket (7) from the sunlight. The slanting surface (6) compresses the gasket (7) providing a stop against both the pin (3) and the ceramic body (1), and limits excessive radial expansion of the compressed gasket towards the outside.
