Abstract

PURPOSE: To prevent refrigerator oil in misted state from leaking, accompained by discharge gas, by opening the upper end of a discharge passage hole provided in the core of a crank shaft, toward an enclosed vessel chamber.
CONSTITUTION: A discharge hole 21 is provide on the center of a flat plate 6a of a rotary scroll 6 in lieu of forming a discharge hole on a fixed scroll 7, while a discharge hole 22, which is in connection with the hole 21, is provided in the core of a crank shaft 4 integrated with a motor shaft. A lateral hole 23 is radially opened at the upper end of the shaft 4 including the hole 22. Drawn into a compression chamber 11 from a suction pip1 10, passing through the hole 21, gas is discharged into an enclosed vessel chamber through an annular passage 26 of a rotary disk 24 and radial holes 27 from the lateral hole 23. Accordingly, refrigerator oil is not atomized in a state of mist because the discharge gas is not discharged into an oil sump 9.
