Claims

[Scope of utility model registration request]

An electric motor and a compression element driven by the electric motor and provided with a crankshaft are respectively disposed inside the airtight container; and a plurality of right-angled holes are formed radially from the oil groove toward the outer periphery of the lower journal portion, and the oil pressurized by centrifugal action inside the right-angled holes is directed toward the center axis of the crankshaft. An oil pump mechanism is provided to send oil to the main oil supply hole passing through the crankshaft, and an oil hole that also serves as eight gas vent holes formed in the axial direction from the annular oil groove to a predetermined depth is provided in the crankshaft. A sealed electric compressor oil pump with a protrusion or recess in the groove.
