A transport refrigeration system including a compressor, an evaporator, a condenser, an air mover assembly for the evaporator and condenser comprising fans and/or blowers, and a prime mover for the compressor having first and second selectable speeds. The speed of the air mover assembly is mechanica
A transport refrigeration system including a compressor, an evaporator, a condenser, an air mover assembly for the evaporator and condenser comprising fans and/or blowers, and a prime mover for the compressor having first and second selectable speeds. The speed of the air mover assembly is mechanically interlocked with the speed of the prime mover via a pulley driven speed changer, to eliminate the possibility of overspeeding of the air mover assembly. The speed changer changes the speed of the prime mover by a mechanical movement which cannot be made without tension in the pulley belts automatically changing the pulley ratio of the speed changer, to maintain a substantially constant speed for the air mover assembly, notwithstanding a change in prime mover speed.

A transport refrigeration system comprising: a compressor, a prime mover for said compressor having selectable speeds via a predetermined mechanical movement, an evaporator, a condenser, air mover means for said evaporator and condenser, speed changer means, pulleys on the prime mover, speed changer
A transport refrigeration system comprising: a compressor, a prime mover for said compressor having selectable speeds via a predetermined mechanical movement, an evaporator, a condenser, air mover means for said evaporator and condenser, speed changer means, pulleys on the prime mover, speed changer means, and air mover means, first and second belts linking pulleys of the prime mover and speed changer means, and pulleys of the speed changer means and the air mover means, respectively, and a mechanical link between the speed changer means and prime mover, said speed changer means having a changeable pulley ratio, with said prime mover driving said air mover means via said speed changer means, said speed changer means mechanically interlocking said prime mover and said air mover means such that physical movement of the speed changer means relative to the prime mover simultaneously initiates the predetermined mechanical movement which selects a prime mover speed via the mechanical link, and tensions the first and second belts to effect a change in the pulley ratio of the speed changer means, whereby the speed of the prime mover cannot be changed without automatically changing the pulley ratio of the speed changer means, and the pulley ratio cannot be changed without automatically changing the speed of the prime mover.
