Abstract:
A hose fitting for connecting a multi-layer hose to a metallic end piece in a compression-proof manner:the multi-layer hose having:a) an elastic and electrically non-conductive layer having an outer surface; andb) at least one underlying layer having characteristics of higher electrical conductivity than the elastic and electrically non-conductive layer, the underlying layer of the multi-layer hose having an inner surface extending beyond the elastic and electrically non-conductive layer;the metallic end piece having:a) an elastic and electrically non-conductive layer;b) at least one underlying layer having conductive characteristics greater than those exhibited by the non-conductive layer of the end piece; andc) an end region characterized by an outward projection of the underlying layer beyond the non-conductive layer, the outward projection having an outwardly oriented surface and at least one bulge extending outward therefrom, at least a portion of the end region and associated bulge engageable with the inner surface of the hose;the hose fitting comprising:a metallic sleeve which encompasses the hose such that the metallic sleeve overlaps the bulge, the metallic sleeve having first and second pressed sections positioned so as to contact and maintain associated regions of the outward projection of the hose in sandwiched relationship between the metallic sleeve and the outward projection of the end piece, the first and second pressed sections located lateral to the bulge and having inner diameters essentially equivalent to one another.
