ABSTRACT:
A flexible coupling suitable for use in an automobile exhaust system having axially spaced conduit sections. Upstream and downstream conduit sections are held end to end by an intermediate coupling member. The upstream conduit has a part-spherical end connector that fits within a complementary part-spherical socket of the coupling member. Similarly, the coupling member has a part-spherical end connector that fits within a complementary part-spherical socket of the downstream conduit. The part-spherical connectors permit relative pivotal and rotational movement of the upstream and downstream connectors relative to the coupling member. Each of the part-spherical connectors tapers internally to an annular lip, so that the flow of gas increases to create a venturi effect. The venturi effect establishes a relative vacuum at the junctions between the coupling member and the conduits to oppose escape of gas (such as exhaust fumes) from the coupling. The coupling member may be curved to accommodate relative axial movement of the upstream and downstream conduit sections.
