Abstract

In a tire valve (10) for the rim (Q) of a pneumatic tire on a vehicle having a valve body (12) which includes a longitudinal bore (16) and which comprises rigid, in particular metal material with a valve base (20) which is arranged at one end and which has an annular shoulder (24) projecting radially from the valve body (12), the valve body (12) is connected at a spacing to a coaxial valve sleeve (48) by an intermediate tube (44) of elastic material and the valve sleeve (48) can be inclined limitedly with respect to the longitudinal axis (A) of the tire valve (10). The valve sleeve is to comprise rigid material—in particular a metal material—; the intermediate tube (44) bears clampingly at one end against a hollow shank (28) of the valve body (12) and at the other end surrounds the end region of the valve sleeve (48), which is in adjacent relationship at a spacing (u).

Claims

1. A tire valve (10) for the rim (Q) of a pneumatic tire on a vehicle having a valve body (12) which includes a longitudinal bore (16) and which comprises rigid, in particular metal material with a valve base (20) which is arranged at one end and which has an annular shoulder (24) projecting radially from the valve body (12), characterised in that the valve body (12) is connected at a spacing to a coaxial valve sleeve (48) by an intermediate tube (44) of elastic material and the valve sleeve (48) can be inclined limitedly with respect to the longitudinal axis (A) of the tire valve (10).

2. A tire valve as set forth in claim 1 characterised in that the valve sleeve comprises rigid material, in particular a metal material.

3. A tire valve as set forth in claim 1 characterised in that the intermediate tube (44) bears clampingly at one end against a hollow shank (28) of the valve body (12) and at the other end surrounds the end region of the valve sleeve (48), which is in adjacent relationship at a spacing (u).

4. A tire valve as set forth in claim 1 characterised in that the mouth opening (35) of the longitudinal bore (16) of the hollow shank (28) is arranged on a head tube (34) delimiting thereon towards the axis an annular shoulder (32).

5. A tire valve as set forth in claim 1 characterised in that in the region of the mouth opening (35) of the hollow shank (28) projecting radially therefrom is at least one external bead (36) forming an outwardly protruding support for the intermediate tube (44).

6. A tire valve as set forth in claim 1 characterised in that the valve body (12) is at least partially surrounded by a screw sleeve (38) which extends at a radial spacing with respect to the external bead (36) of the hollow shank (28) and forms therewith a clamping pairing arrangement for the intermediate tube (44).

7. A tire valve as set forth in claim 6 characterised in that the screw sleeve (38) is connected in surface contact in force-locking surface relationship with a region of the intermediate tube (44), which bears against the screw sleeve at the inside.

8. A tire valve as set forth in claim 6 characterised in that the screw sleeve (38) is connected by a vulcanisation procedure to a region of the intermediate tube (44) which bears against the screw sleeve at the inside.

9. A tire valve as set forth in claim 1 characterised in that the end region of the intermediate tube (44) which is associated with the valve sleeve (48) is connected in force-locking relationship to the adjacent sleeve surface.

10. A tire valve as set forth in claim 9 characterised in that the end region of the intermediate tube (44) which is associated with the valve sleeve (48) is vulcanised to the adjacent sleeve surface.

11. A tire valve as set forth in claim 3 characterised in that in the region of an annular edge (46) of the intermediate tube (44) an external ring (50) of the valve sleeve (48) bears against the intermediate tube at the inside, the external ring being connected in surface contact in force-locking relationship to the intermediate tube.

12. A tire valve as set forth in claim 11 characterised in that the external ring (50) is connected to the intermediate tube (44) by a vulcanising procedure.

13. A tire valve as set forth in claim 1 characterised in that a ring (42) of elastic material as a support member for the rim (Q) extends between the annular shoulder (24) of the valve base (20) and the oppositely disposed lower edge (39) of the screw sleeve (38) and an annular disk (40) of rigid material is provided between the lower edge (39) of the screw sleeve (38) and the elastic ring (42).

14. A tire valve as set forth in claim 1 characterised in that the free spacing (n) between the valve body (12) and the valve sleeve (48) corresponds approximately to between a sixth and a seventh of the valve length (a).

15. A tire valve as set forth in claim 1 characterised in that the length (n) of the intermediate tube (44) corresponds approximately to the length (c or n₁) of the valve body (12) and the valve sleeve (48) respectively.

16. A tire valve as set forth in claim 1 characterised in that the length (c) of the valve body (12) is somewhat greater than the length (n₁) of the sleeve (48).

17. A tire valve as set forth in claim 1 characterised in that the length (q) of the overlap region of the intermediate tube (44) and the screw sleeve (38) corresponds approximately to between a third and a quarter of the length (c) of the valve body (12).

18. A tire valve as set forth in claim 1 characterised in that the length (y) of the overlap region of the intermediate tube (44) and the valve sleeve (48) corresponds approximately to between a third and half the length (n₁) thereof.
