First Claim
1. Apparatus for mounting on a rim of a vehicle wheel on which a tire may be mounted, said apparatus comprising:
- a pressure sensor for sensing the pressure in the tire, said pressure sensor having a housing with a pocket in said housing;
a threaded fastener mounted in said pocket in said housing, said threaded fastener having a threaded portion extending along an axis;
said threaded fastener and said housing having surfaces blocking rotation of said threaded fastener about said axis; and
a tire valve stem for projecting through a first opening in the rim and through a second opening in said housing into said pocket, said tire valve stem having a threaded portion for threaded engagement with said threaded portion of said threaded fastener upon relative rotation of said threaded portion of said threaded fastener and said threaded portion of said valve stem about said axis, said tire valve stem and said threaded fastener clamping a part of said housing between said tire valve stem and said threaded fastener when said threaded portion of said threaded fastener and said threaded portion of said valve stem are threaded together.

Abstract
An apparatus 10 mounts on a rim 11 of a vehicle wheel 13 on which a tire 12 may be mounted. The apparatus 10 comprises a tire pressure sensor 20, a first threaded fastener 30, and a tire valve stem 40. The tire pressure sensor 20 senses the pressure in the tire 12 and has a housing 21 with a pocket 22. The first threaded fastener 30 is mounted in the pocket 22 in the housing 21 and has a first threaded portion 31 extending along an axis 100. The first threaded fastener 30 and the housing 21 have surfaces 25, 26, 35 blocking rotation of the first threaded fastener 30 about the axis 100. The tire valve stem 40 projects through a first opening 17 in the rim 11 and through a second opening 27 in the housing 21 into the pocket 22. The tire valve stem 40 has a second threaded portion 41 for threaded engagement with the first threaded portion 31 upon relative rotation of the first 31 and second threaded portions 41 about the axis 100. The tire valve stem 40 and the first threaded fastener 30 clamp a part 21a of the housing 21 between the tire valve stem 40 and the first threaded fastener 30 when the first 31 and second 41 threaded portions are threaded together.
