Patent ID: 8701423

Claim:
A modified air-conditioning compressor used for a motorized vehicle, said modified compressor comprising: a refrigerant compressor, said refrigerant compressor having a first housing end bell, said refrigerant compressor having a second housing end bell, said refrigerant compressor having an inlet and an outlet for transporting refrigerant, and said refrigerant compressor having a central drive shaft that when turned with rotational force causes said compressor to compress refrigerant gasses contained therein; a first compressor-driving pulley adapted to facilitate the rotational driving of said compressor from a first power source via the use of a pulley belt; an electric clutch assembly adapted to facilitate the selective coupling of said first pulley with said central drive shaft, when said electric clutch assembly is energized; and a second compressor-driving pulley directly coupled to said central drive shaft to facilitate the rotational driving of said compressor from a second power source via the use of a pulley belt; wherein: said first and second compressor-driving pulleys are mounted on opposite ends of said central drive shaft with respect to each other; said central drive shaft is modified to extend beyond each compressor housing end bell in order to support one of said first and second pulleys at each end of said compressor; each of said first and second housing end bells are substantially structurally identical, each having a bearing adapted to support said central drive shaft and each having packing seals for inhibiting the leakage of either lubricants or refrigerant; at one end of said compressor, said electric clutch assembly is equipped with an outer hub at which said first compressor-driving pulley is adapted to be selectively coupled to said central drive shaft; and at the other end of said compressor, said second compressor-driving pulley is directly coupled to said compressor's drive shaft via the neck of respective housing end bell, onto which is installed an additional roller bearing.
