Abstract
A closed type motor-driven compressor includes a motor accommodated in a closed container and a compression mechanism connected through a crank shaft to the motor. A shielding member having a cylindrical portion substantially concentric with the axis of the compression mechanism is disposed between the motor and the compression mechanism. This shielding member defines a shielding air space between the motor and the compression mechanism for preventing a permeation of a lubricating oil. An inlet of a discharge pipe of the closed type motor-driven compressor is positioned inwardly of this shielding air space.
