Abstract
Abstract Cooling apparatus for an automobile vehicle comprising a compressor, an evaporator, a condenser and a fan associated with the condenser. The compressor and the fan are adapted to be driven by the vehicle engine through respective electromagnetic clutches controlled through electric control circuits. This apparatus is improved in that cut out means are inserted in the electric control circuit of the compressor and/or fan. The cut out means are controlled by a control member controlling the acceleration of the vehicle so as to release automatically the clutch of the compressor and/or fan when the control member reaches a given position.
