Open the CIPO recordAbstract From the Canadian patent
Gas powered refrigeration units typically utilize a pressure reducing valve after the primary generator to reduce the pressure prior to the secondary generator in the case of a double effect system or prior to the absorber in a single system. In this invention a fluid, powered pump takes the place of the pressure reducing valve and pressurizes the refrigeration fluid from the output of the absorber from the input to the primary generator. The utilization of this motor enables a much reduced use of the main motor in the system and allows substantial reduction in the amount of energy required for operation in the system.
