Abstract

This invention describes a bypass valve, which allows a controlled, variable amount of Freon to continuously flow from the high pressure side of an air conditioning system to the low pressure side without passing through the compressor or radiator. Said valve is only fully closed when maximum cooling is desired. Said valve requires only a simple set-point thermostat and servo motor to automatically control automobile cabin temperature, while giving maximum savings of engine power and fuel economy.

Claims

exact text as granted — not AI-modified
1 . I claim that the invention consists of a pathway for a portion of the refrigerant working fluid to bypass from the high pressure side of the compressor to the low pressure side in continuous flow, at all times except maximum cooling demand, without passing through the condenser or radiator.  
   
   
       2 . I claim that the bypass of working fluid around the compressor as described in  claim 1  is controlled by a variable valve.  
   
   
       3 . I claim that the bypass of working fluid around the compressor as described in  claim 1  is controlled by a needle valve.
