Receiver having expansion mechanism

A receiver located in a refrigerating circuit that includes a compressor, a condenser, an expansion valve and an evaporator, wherein said receiver receives and temporarily reserves liquefied refrigerant sent from the compressor by way of the condenser, wherein said expansion valve atomizes the liquefied refrigerant sent from the receiver and supplies the atomized refrigerant to the evaporator, said receiver comprising:

• a tank for reserving the liquefied refrigerant sent from the condenser;
• a head portion located on said tank, wherein said head portion has a first passage for introducing the refrigerant from the condenser to the tank, a second passage for supplying the refrigerant from the tank to the evaporator and a third passage for transferring the refrigerant to the compressor from the evaporator, and wherein said head portion houses said expansion valve;
• an adjusting mechanism and a control mechanism included in said expansion valve, wherein said adjusting mechanism is located in said second passage to adjust the flow rate of the refrigerant supplied to the evaporator from the tank, and wherein said control mechanism is located in said third passage to control said adjusting mechanism in accordance with the temperature of the refrigerant flowing in the third passage;
• a first charging valve located in the head portion in the first passage to charge the refrigerant into the first passage;
• and
• a second charging valve located in the head portion in the third passage to charge the refrigerant into the third passage.
