Abstract
A composite gasket (1) arranged to be frictionally fitted around a rigid tube end (2) is designed for insertion into a part (3) provided with an aperture (4) in the form of a cylindrical bore for coupling with the tube end. The gasket includes at least one ring (5) made of an elastomeric material and at least one collar (6) made of a rigid material in the shape of a cylindrical sleeve parallel to and coaxial with the ring axis. The collar is adjacent to the ring and has an outer surface (9) suitable for mild frictional engagement with the inner surface (10) of the coupling aperture, while the shape of the ring-engaging end surface of the collar matches that of the ring.
Claims14
A composite gasket for a rigid pipe connector capable of being inserted into a component provided with a connecting orifice in the form of a cylindrical bore, for connection to said connector, said gasket comprising at least one collar made from elastomeric material, said collar being arranged around an axis, and at least one ring made from rigid material, said ring being of annular shape and being located entirely on one side and in the axial prolongation of the collar, said ring having an axis coinciding with the axis of the collar, and having an outer surface capable of cooperating by soft friction with the inner face of the connecting orifice, said ring being in the form of a cylindrical sleeve having a longitudinal dimension between 1.5 times and 5 times the radial thickness of said ring and having an inner surface capable of cooperating by soft friction with the outer face of the connector directly or via an end part of the collar, said composite gasket being designed to be slipped frictionally on the connector, said collar being fixed to the ring, and having a junction end with the ring of a shape complementary to a corresponding junction end of said ring with said collar, so as to match at least partially the shape of the edge of said collar.
A component/pipe assembly comprising:
- a component provided with a connecting orifice in the form of a cylindrical bore having an inner face,
- a rigid pipe connector having an outer face inserted within said connecting orifice,
- a composite gasket comprising at least one collar made from elastomeric material, said collar being arranged around an axis, and at least one ring made from rigid material, said ring being of annular shape and being located entirely on one side in the axial prolongation of the collar with an axis coinciding with the axis of the collar, said ring having an outer surface cooperating by soft friction with the inner face of the connecting orifice, said ring being in the form of a cylindrical sleeve having a longitudinal dimension between 1.5 times and 5 times the radial thickness of said ring and having an inner surface cooperating by soft friction with the outer face of the rigid pipe connector either directly or via an end part of the collar,
- the gasket having been slipped frictionally on the connector, said collar being fixed to the ring and having a junction end with the ring of a shape complementary to a corresponding junction end of said ring with said collar so as to match at least partially the shape of the edge of said collar and,
- a fastening plate for securing the pipe to the component.
