Abstract

A module for detecting a physical value of a gaseous medium includes a discrete component including a detection section on a surface, the discrete component being configured to detect the physical value of the gaseous medium that acts on the detection section, a supply-line component configured to introduce the gaseous medium to the detection section, a seal in contact with the supply-line component and the surface of the discrete component and configured to fluidly seal the detection section on the surface of the discrete component. The seal includes a seal lip configured to enclose the detection section such that the seal forms a sealing space, the sealing space including the detection section and being separated from an external space by the seal.

First claim

What is claimed is:

1. A module for detecting a physical value of a gaseous medium, the module comprising:
a discrete component including a detection section on a surface, wherein the discrete component is configured to detect the physical value of the gaseous medium that acts on the detection section;
a supply-line component configured to introduce the gaseous medium to the detection section; and
a seal in contact with the supply-line component and the surface of the discrete component and configured to fluidly seal around the detection section on the surface of the discrete component,
wherein the seal includes a seal lip configured to enclose the detection section such that the seal forms a sealing space, the sealing space comprising the detection section and being separated from an external space by the seal,
wherein the seal lip includes a seal edge configured to be in contact with the surface of the discrete component, and wherein the seal lip, starting from the seal edge, has a cross-section that is larger starting from a pressureless state of the seal if the seal is configured for a pressure of the gaseous medium that is greater than the pressure in the external space.

2. The module according to claim 1 , wherein the supply-line component includes a seal seat configured to receive the seal.

3. The module according to claim 1 , wherein the discrete component is an integrated circuit in a housing.

4. The module according to claim 1 , further including a circuit board, the discrete component being indirectly or directly attached to the circuit board and the discrete component being in electrical contact with the circuit board.

5. The module according to claim 4 , further comprising a housing enclosing at least the circuit board and the seal.

6. The module according to claim 5 , wherein the housing comprises a preloading structure configured to exert a force on the circuit board such that the seal is preloadable against the supply-line component via a mechanical attaching of the discrete component to the circuit board.

7. The module according to claim 1 , wherein the supply-line component comprises an attachment structure configured to make the module attachable to a valve of the tire, and wherein the valve provides a fluid access to an interior of the tire.

8. The module according to claim 7 , further including a valve to make the gaseous medium in the interior of the tire refillable via the attachment structure.

9. The module according to claim 1 ,
further including a circuit board, the discrete component being indirectly or directly attached to the circuit board and the discrete component being in electrical contact with the circuit board, and a housing enclosing at least the circuit board and the seal,
wherein the supply-line component includes a seal seat configured to receive the seal,
wherein the discrete component is an integrated circuit in a housing,
wherein the housing comprises a preloading structure configured to exert a force on the circuit board such that the seal is preloadable against the supply-line component via a mechanical attaching of the discrete component to the circuit board, and
wherein the supply-line component comprises an attachment structure configured to make the module attachable to a valve of the tire, and wherein the valve provides a fluid access to an interior of the tire fluid.

10. A tire pressure monitoring system including the module according to claim 1 .

11. A module for detecting a physical value of a gaseous medium, the module comprising:
a discrete component including a detection section, the detection section being configured to contact the gaseous medium, the discrete component being configured to detect the physical value of the gaseous medium;
a supply-line component configured to introduce the gaseous medium to the detection section; and
a seal element forming a seal between the supply-line component and a surface of the discrete component and configured to fluidly seal the detection section from an external space,
wherein the seal includes a seal lip surrounding the detection section and forming a sealing space separate from the external space,
wherein the seal lip includes a seal edge configured to be in contact with the surface of the discrete component, and wherein the seal lip, starting from the seal edge, has a cross-section that is larger starting from a pressureless state of the seal if the seal is configured for a pressure of the gaseous medium that is greater than the pressure in the external space.

12. The module according to claim 11 , wherein the supply-line component includes a seal seat configured to receive the seal.

13. The module according to claim 11 , wherein the discrete component is an integrated circuit in a housing.

14. The module according to claim 11 , further including a circuit board, the discrete component being indirectly or directly attached to the circuit board and the discrete component being in electrical contact with the circuit board.

15. The module according to claim 14 , further comprising a housing enclosing at least the circuit board and the seal.

16. The module according to claim 11 , wherein the supply-line component comprises an attachment structure configured to make the module attachable to a valve of the tire, and wherein the valve provides a fluid access to an interior of the tire.

17. A tire pressure monitoring system including the module according to claim 11 .
