Abstract

This sealing device for a railway, the railway including a housing extending between a side face of a rail and a side wall of a slot reserved in the ground for housing said rail, is characterized in that it is a sealing device inserted in the housing and fixed in the housing by a suitable putty, and in that it is a resiliently deformable profile, to be able to be inserted under stress in the housing and to be pressed against the side face of the rail and the side wall of the slot.

Claims (56)

1. A sealing device for a railway, the railway including a housing extending between a side face of a rail and a side wall of a slot reserved in the ground for housing the rail, wherein the sealing device is configured to be inserted in the housing and fixed in the housing by a fastening putty, and wherein the sealing device has a resiliently deformable profile, which is configured to be under stress upon being inserted in the housing so as to press against the side face of the rail and the side wall of the slot.

2. The sealing device according to claim 1 , having a cross-section including a “V” pattern, the “V” pattern being deformable resiliently to modify a width of the sealing device.

3. The sealing device according to claim 2 , wherein the “V” pattern is made up of a first angled wall and a second angled wall, which are connected to one another with a rim a thickness of the rim being refined relative to a thickness of the first and second angled walls so as to allow a resilient deformation of the “V” pattern by modifying an angle between the first and second angled walls.

4. The sealing device according to claim 2 , wherein the cross-section is symmetrical along a median axis.

5. The sealing device according to claim 4 , including a right wing and a left wing, each wing including a “V” pattern.

6. The sealing device according to claim 5 , including a central core on either side of which the right and left wings are connected, the central core being configured to bear on a bottom of the housing.

7. The sealing device according to claim 6 , including an upper portion connected to an upper face of the central core and extending transversely so as to cover the “V” pattern of each wing of the sealing device.

8. The sealing device according to claim 1 , having a cross-section including at least one lip on a side end, the at least one lip being resiliently deformable to modify a width of the sealing device.

9. The sealing device according to claim 8 , wherein the cross-section is symmetrical along a median axis.

10. The sealing device according to claim 9 , wherein the at least one lip is inclined relative to the median axis of the sealing device so as to move upward during insertion of the sealing device into the housing.

11. The sealing device according to claim 8 , including a central core on either side of which right and left wings are connected, the central core configured to bear on a bottom of the housing and each wing being provided, on the side of a side end of the sealing device, with a pair of lips.

12. The sealing device according to claim 1 , including side ends having an arc of circle-shaped contour.

13. The sealing device according to claim 1 , made from a polymer material.

14. The sealing device according to claim 13 , wherein the polymer material is a synthetic rubber.

15. A railway comprising:
