Definitions
- the invention relates to a pipe for transporting fluids, having at least one end forming a connection section to a nozzle of a member to be connected.
- Such lines are for example used in power steering systems for automobiles in order to connect the reservoir of steering fluid to the pump, or even in the fuel circuits.
- the invention also relates to the connection made with such a pipe.
- a pipe for transporting fluids having at least one end forming a connection section to a nozzle of a member to be connected.
- Such lines are for example used in power steering systems for automobiles in order to connect the reservoir of steering fluid to the pump, or even in the fuel circuits.
- the invention also relates to the connection made with such a pipe.
- To connect the pipe to a rigid reservoir end piece having an end bulge it is known to use a flexible sleeve mounted inside one end of the pipe. Securing the pipe to the end piece is achieved by means of a clamping collar arranged on the pipe between its end and the end bulge of the end piece to
- Driving is implemented by fit- force the pipe provided with its sleeve on the nozzle, and then by arranging the clamping collar to 'driving.
- the fitting effort is a paramount parameter of the cost and the arduousness of the fitting operation.
- a pipe having a connection section allowing an easy and tight fitting on the end piece of the member to be connected.
- a pipe having at least one end portion forming a connection section on a rigid end piece and comprising an internal tubular lining of elastic material remarkable in that at least one wave s extending longitudinally is formed on the end portion of the pipe.
- the wave makes it possible to give the end of the pipe the radial elasticity ' necessary for the easy fitting of the pipe onto the end piece.
- the end portion is wavy over its entire circumference.
- the internal diameter of the waves is then chosen to induce a tightening of the liner on the end piece.
- a non-corrugated cylindrical part is provided on the end portion between the corrugated part and the pipe itself.
- this bulge can be housed in this cylindrical part, allowing the corrugated portion radially deformed by the bulge to shrink on the cylindrical part of the end piece.
- the end portion of the pipe ends in a swollen cylindrical part.
- This terminal bulge is intended to provide a face which comes to bear on a collar of the sleeve, with a view to sealing between the pipe and the sleeve.
- FIG. 1 is a perspective view of a pipe according to the invention
- Figure 2 is a longitudinal sectional view of the pipe
- Figure 3 is a sectional view perpendicular to the axis of the pipe.
- a pipe 1 of axis X is distinguished, one end of which 2 has an internal diameter suitable for accommodating, in a manner known per se, an internal tubular liner in the form of an elastic sleeve 5.
- the pipe 1 is for example made of polyamide, having a low elasticity.
- the sleeve 5 is in turn made of a material of the elastomer type, for example cellular polyvinyl chloride or rubber, having a high elasticity.
- the sleeve 5 has a collar 6 intended to come to bear against the terminal face 3 of the pipe 1.
- the end 2 has waves 4 of extension longitudinal. These waves give the end 2 a radial elasticity capable of facilitating the fitting of a nozzle 7 equipped with an end bulge 8.
- FIG. 2 which is a view in longitudinal section along the axis X
- the end bulge 8 expands the sleeve 5, which itself even expands the end 2, playing on the elasticity that the waves give it.
- the cylindrical part of the end piece 7 after the passage of the end bulge 8. This ensures radial tightening of the end piece 7 by the corrugated area the end 2 of the pipe 1 via the sleeve 5.
- the resistance of the corrugated area at its radial expansion adds to the friction between the different elements to provide a very simple means to prevent inadvertent separation of the pipe 1 and the nozzle 7 by a simple pull.
- the collar 6 comes to bear on the end face 3 of the pipe 1, produced on a swollen cylindrical end portion 9 upstream of the waves 4 in the driving direction.
- connection of the pipe 1 to the end piece 7 is secured by a collar 11 put in place and tightened around the end 2 at the level of the waves 4.
- the tightening of the collar 11 is not necessary to ensure the tightness of the connection, which is already provided by the waves 4.
- the collar 11 only serves to prevent the radial extension of the waves 4 in the event of traction on the pipe 1.
- the end 2 can be attached to the pipe 1; the seal between the end 2 and the sleeve 5 can be obtained by crushing the sleeve which completely matches the external shape of the end 2; The connection is still valid even if the end piece 7 does not have an end bulge 8. In which case the tightening of the collar 11 will secure the pipe 1 on the end piece 7 by friction.
- the sleeve 5 can be a tubular insert molded on the pipe 1.
