Patent ID: 7726952

Claim:
An arrangement for a compressed air system in a vehicle, comprising a connection ( 6 , 10 ) for delivering compressed air from a compressor ( 2 ) to the rest of the compressed air system ( 1 ), said compressor having a relief phase of operation, and an oxidation catalytic converter ( 9 ), which cleans the compressed air and which is located along said connection ( 6 , 10 ), wherein said connection ( 6 , 10 ) comprises a line ( 10 ) which forms a connection between the oxidation catalytic converter ( 9 ) and the rest of the compressed air system, wherein a valve ( 11 ) is provided upstream of the rest of the compressed air system ( 1 ), said valve ( 11 ) having a first position in which said valve will allow air delivery from said compressor to the rest of the compressed air system and a second position in which said valve will prevent delivery of air to the rest of the compressed air system ( 1 ), and wherein said valve ( 11 ) is operationally connected to and controlled by a control unit ( 13 ) which is, in turn, operationally connected to said compressor ( 2 ), said control unit ( 13 ) determining whether the compressor ( 2 ) is in its relief phase and setting the valve ( 11 ) to said first or said second position based on that determination.
