Abstract

This electric compressor comprises: a housing that includes a stator having a cylindrical shape; a rotating shaft that is disposed inside the housing and that has a rotor facing the stator; a low pressure wheel that is fixed to one axial side of the rotating shaft; a high pressure wheel that is fixed to the other axial side of the rotating shaft; a low pressure side air bearing that rotatably supports, in the housing, a low pressure side shaft section of the rotating shaft; a high pressure side air bearing that rotatably supports, in the housing, a high pressure side shaft section of the rotating shaft; a first air flow path that supplies compressed air from the housing to either one of the low pressure side air bearing and the high pressure side air bearing; a second air flow path that branches from the first air flow path and that supplies the compressed air to the other of the low pressure side air bearing and the high pressure side air bearing; and an air flow rate adjustment device that adjusts a flow rate of the compressed air flowing in the first air flow path and the second air flow path.
