Abstract: The cooling system includes a cyclically operating cooling-medium compressor driven by the vehicle engine. At low to medium engine speeds, corresponding to speeds from idling to city-driving speeds, the cooling system develops a cooling power sufficient to satisfactorily cool the interior of the passenger compartment. At higher engine speeds, corresponding to highway travel, the cooling power developed by the cooling system is automatically decreased by automatically decreasing the per-cycle volumetric throughput of the cooling-medium compressor. The automatic decrease is effected in automatic response to the reaching of a certain engine rpm or a certain condensation pressure in the condenser of the cooling system. In the illustrated embodiment, the compressor is a sliding-vane compressor, and the per-rotation volumetric throughput thereof is decreased by arresting certain ones of the vanes in the retracted position.
