Abstract
PURPOSE: To bring down the lower limit of the operating temperature of a refrigerator by introducing the oil from an oil separator to a shaft sealing chamber with the aid of the pressure of a refrigerant gas and filling this shaft sealing chamber with positive pressure oil.
CONSTITUTION: A crank shaft 12 is installed in a crank room 11 in such a manner that it can rotate freely, and the gas fed back from an evaporator side is sucked in from a suction tube be turning the crank shaft 12 and further sent to an oil separator 4 through a discharge collecting pipe 15 and a tube 3. The oil separated and stays at the bottom of the oil separator 4 is sent to which is a shaft sealing room 18 through a return pipe 8 with the aid of the high pressure of a refrigerant gas in the oil separator 4 to fill the shaft sealing room 18 with positive pressure oil. Thereby, the shaft sealing part 9 sealed mechanically by a shaft sealing device 19 is further sealed liquid-tightly, so that suction of air through this part is prevented and negative pressure driving becomes possible. Thus, refrigerating operation can be made in the lower temperature zone than the lower limit of the inside working temperature according to any conventional construction.
