US 7,726,952 B2 · Arrangement and method for compressed air systems in vehicles

Abstract

Method and arrangement for providing a compressed air system in a vehicle that includes a connection (6, 10) for delivering compressed air from a compressor (2) to the rest of the compressed air system (1). An oxidation catalytic converter (9) is included that is designed to clean the compressed air and which is located along the connection (6, 10). The connection (6, 10) includes a line (10) that forms a connection between the oxidation catalytic converter (9) and the rest of the compressed air system. The invention also includes a valve (11) that is arranged upstream of the rest of the compressed air system (1) and that can be adjusted so that in a first position it will allow and in a second position will prevent the delivery of air to the rest of the compressed air system (1), depending on the operating condition of the compressor (2). The invention provides an improved system in which the risk of contaminated air being delivered to the compressed air system is minimized.

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.

An arrangement for providing compressed air in a vehicle, said arrangement comprising:

a compressor (2) connected to a compressed air system (1) by a connection (6, 10) and delivering compressed air from the compressor (2) to the compressed air system (1), said compressor having a relief phase of operation;
an oxidation catalytic converter (9) that cleans the compressed air, said oxidation catalytic converter (9) being located along said connection (6, 10) and said connection (6, 10) comprising a line (10) that forms a connection between the oxidation catalytic converter (9) and the compressed air system;
and
a valve (11) which is arranged upstream of the compressed air system (1) and which is adjustable between a first position that permits air delivery to the compressed air system (1) and a second position that prevents delivery of air to the compressed air system (1);
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.
