Abstract

An electronic circuit (1) compares a reference voltage (Vr) representing a pressure set by the user by means of an adjusting device with a voltage (Vp) representing the air pressure in the tyre and produced by a pressure/voltage transducer (3). The difference signal from this comparison controls the addition or removal of air to or from the tyre until the air pressure set by the user is reached. Pref. addition of air is through an electrically controlled inlet valve (4) and removal of air is through an electrically controlled discharge valve (5). Differenty tyre pressures for different vehicle makes may be set automatically by a logic unit (7) e.g. fron punched card or tape input.
