Patent ID: 7743627

Claim:
A vehicle air conditioning system comprising: a condenser being configured to receive a refrigerant in a compressed state and remove heat from at least a portion of the refrigerant; a pressure reducing device in fluid communication with the condenser to receive the refrigerant, and configured to reduce pressure of the refrigerant from the condenser; an evaporator in fluid communication with the pressure reducing device to receive the refrigerant, and configured to evaporate at least a portion of the refrigerant; and a compressor assembly including a housing, a refrigerant flow booster having an inlet in fluid communication with the evaporator, and configured to boost the pressure of the refrigerant from the evaporator and an outlet refrigerant passageway, and a compressor configured to compress the refrigerant and having an outlet to deliver the refrigerant in the compressed state to the condenser, the compressor having an inlet refrigerant passageway, the refrigerant flow booster and the compressor being integrally formed as a single unit within the housing, with the outlet refrigerant passageway and the inlet refrigerant passageway being directly connected to one another and contained completely within the housing between the inlet of the refrigerant flow booster and the outlet of the compressor for conveying the refrigerant from a booster chamber of the refrigerant flow booster directly into an interior of the compressor.
