Scroll compressor

A scroll compressor comprising:

• a casing having a casing body in which a housing space having a columnar shape around an axis is formed, and a bearing holder having an annular shape by protruding inward in a radial direction from an inside of the casing body and which is formed so as to divide the housing space into a motor housing space located on one side in an axial direction and a compression unit housing space located on the other side in the axial direction;
• a rotary shaft that is located to extend in the axial direction in the housing space, and that is rotatable around the axis;
• a motor that is located in the motor housing space, and having a stator having an annular shape formed around the axis and having an outer peripheral surface fixed to an inner peripheral surface of the casing body, and a rotor located inside the stator and disposed on an outer peripheral surface of the rotary shaft;
• a scroll compression unit that is located inside the compression unit housing space, and which is configured to compress a fluid flowing from the motor housing space to the compression unit housing space;
• a first radial bearing that is fixed to an inner peripheral surface of the bearing holder, and rotatably supporting the rotary shaft;
• a thrust bearing having an annular shape formed around the axis, that is fixed to a surface of the bearing holder facing the other side in the axial direction, and supporting the scroll compression unit in the axial direction;
• and
• a thrust plate disposed between the bearing holder and the scroll compression unit in the axial direction,
• wherein the outer peripheral surface of the stator has a stator groove portion which extends from one end to the other end of the stator in the axial direction,
• wherein a plurality of the stator groove portions are located at an interval in a circumferential direction of the stator,
• wherein in the bearing holder, portions corresponding to formation positions of the plurality of stator groove portions each have a flow path penetrating the bearing holder in the axial direction,
• wherein in the thrust bearing, a portion facing the flow path has a first recess portion recessed from one side in the axial direction to the other side in the axial direction,
• wherein an outer peripheral portion of the first recess portion has a first groove portion which extends from a bottom surface of the first recess portion to a surface located on a side opposite to a surface having the first recess portion formed thereon in the axial direction and communicates with the first recess portion, and
• wherein in an outer peripheral portion of the thrust plate, a portion facing the first groove portion has a second groove portion extending from one surface to the other surface, which are located in the axial direction.
