ABSTRACT:
This invention seeks to provide a cooling device for a hermetic motor-driven compressor, which may effectively carry out not only lubrication, but cooling of a piston and a cylinder by making refrigeration oil in a hermetic casing to circulate in the interior of the piston for removing frictional heat generated between the piston and the cylinder during operation. To this end, the device comprises a crankshaft for drawing up and spouting out the refrigeration oil circulating in the interior of the piston to cool the piston, and a movable portion formed integrally with the connection portion and linearly reciprocably movable in the cylinder for compressing refrigerant gas.
