Title: Automotive air conditioning system with variable speed traction drive transmission

Abstract: An automotive air conditioning system including series connected condenser, expansion valve and evaporator components having refrigerant supplied thereto by a mechanical refrigerant compressor; the refrigerant compressor includes a drive shaft connected to the output of a variable speed traction drive transmission having an input shaft connected to a belt pulley for drive from the vehicle engine. The transmission includes a compact carriage that supports friction cones at opposite ends thereof and includes an axially adjustable speed transfer spool for bridging first and second pluralities of friction cones on either end of the carriage to vary the power transfer from the input shaft to an output shaft so as to manually adjust the circulation of refrigerant flow through the system in accordance with ambient temperature conditions.
