<p>An air braking system of a vehicle has a compressor (11), non-return valve (16), manifold (20), electrically actuable demand valve (21), an air consumer circuit (2.1). An auxiliary circuit connects the manifold (20) to the consumer circuit (2.1) via an electrically actuable valve (26) and non-return valve (31). In the event of electrical failure, air under pressure can be supplied to the consumer circuit (2.1) via the auxiliary circuit. In another aspect a plurality of consumer circuits (2.1, 2.2) are provided. These circuits may be charged from the compressor (11) via the manifold, or interconnected via the manifold independently of the compressor. This arrangement permits more flexible compressor operation and/or a greater reserve in the event of failure of the pressure sourc.e</p> |
