Tire valve and associated tire pressure sending unit
First Claim
1. A tire pressure sending unit comprising:
- a housing;
at least two batteries and a radio-frequency transmitter disposed in the housing, said transmitter powered by the batteries and operative to send a radio-frequency signal;
a load-bearing element extending from the housing and adapted to secure the housing to a tire valve;
said batteries each disposed on a respective side of the load-bearing element.

Abstract
A snap-in tire valve includes a valve body surrounded in part by a resilient element that forms an annular sealing surface configured to snap in place into a valve opening of a wheel. A tire pressure radio-frequency sending unit is mounted to the valve body, and a column extends from the sending unit. The region between the resilient element and the pressure sending unit defines an expansion volume that receives displaced portions of the resilient element during snap-in insertion of the valve body into a wheel opening, thereby facilitating insertion. Preferably the column defines a central passageway to facilitate insertion using standard insertion tools. In one version, two batteries are included in the sending unit, disposed on opposite sides of the column.
