Abstract

The device consists of an electro-mechanical detector device. This detects two pressures, one above, and one below, the pressure normally desired. This device sets in motion an alarm when either upper or lower limit is reached. This alarm can be luminous, audible, or both. The detector can have the settings varied by spring pressure and two distinct types of alarm are given. A detector is fitted to each tyre and whilst there may be a single audible alarm, individual luminous indication is given. Suitable means are provided for conveying the signals from the moving wheel to the vehicle interior.
