Tyre inflation/deflation device
First Claim
Patent Images
1. A device (1) for effecting automatic nitrogen filling from a nitrogen source, or nitrogen-for-air substitution, for the simultaneous inflation/deflation of a plurality of vehicle tyres, comprising:
- multiple controllers (17), each of said controllers adapted to deliver nitrogen to at least one of the tyres based at least partially on a pressure within that tyre, each controller including a processor located on a PCB and each controller being in communication with each of the following;
an individual display (8) for displaying the pressure in the tyre;
a pressure sensor (9) for sensing the pressure in the tyre;
an inflation valve (4) for receiving nitrogen from the nitrogen source and delivering the nitrogen to the tyre;
a deflation valve (11) for releasing pressure from the tyre; and
means for enabling simultaneous setting of a target pressure by linking two of the multiple controllers via an interface link between the processors;
whereby the plurality of vehicle tyres may be inflated/deflated simultaneously, with user input interfaces (10) for pressure setting adjustments.

Abstract
A device (1) for effecting automatic nitrogen filling, or nitrogen-for-air substitution, for the simultaneous inflation/deflation of a plurality of vehicle tires, comprising multiple controllers (17) corresponding to the number of tires to be inflated/deflated, each having an individual display (8), a pressure sensor (9), an inflation valve (4) and a deflation valve (11), whereby multiple vehicle tires may be inflated/deflated simultaneously, with user input interfaces (10) for pressure setting adjustments.
