Abstract
A compressor with a built-in electric motor has a compression mechanism and the built-in electric motor which are housed in a container. A suction port, a discharge port, inner and outer electric connection parts, and mounting legs of the container are provided on the same side of a body of the container. A bearing part for supporting an end of a driving shaft for driving the compression mechanism is formed on an end wall integral to -the body of the container, where the end of the driving shaft to be supported by the bearing part is located in the direction opposite to the compression mechanism and the driving shaft is connected to the built-in electric motor. In addition, a pumping mechanism is provided in a pumping chamber opened to an external surface of the end wall and is connected to the end of the driving shaft in the direction opposite to the compression mechanism. The opening of the pumping chamber is closed by a closing member. Thereby, the reduction in size and weight of the compressor with the built-in electric motor is achieved.
