The invention relates to a device for controlling an air compressor (1) in a motor vehicle, the engine (2) of which is arranged to power the air compressor (1), with compressed air being fed to at least one user (9), comprising a control unit (17) for the detection of a predetermined operational condition of the vehicle and for the control of the function of the air compressor (1). The invention is characterized in that it comprises first means (12) for the detection of a first predetermined pressure level (pL) of said compressed air, and second means (11) for detecting a second predetermined pressure level (pH) of the compressed air, with the second level (pH) being higher than the first level (pL), and with the control unit (17) and said means (11, 12) being arranged to deactivate the air compressor (1) at said second pressure level (pH) in the case of said operational condition, and at said first pressure level (pL) when said operational condition is not present. By means of the invention, an improved device is obtained for the control of the function of an air compressor, which permits a reduced amount of fuel in the engine, and which ensures that charging of air at a minimum air pressure always occurs. |
