    Abstract: A co-rotating scroll compressor is provided in which a bearing configured to support a scroll is displaced by a torque repulsive force, which is applied to the bearing due to compression repulsion of a compressed fluid, the torque repulsive force is converted into a sealing force of compression chambers, which are defined by wraps of co-rotating scrolls such that the sealing force of the compression chambers is increased, and in which a bearing housing is rotatably installed in a housing accommodation hole, a rotational center of a second scroll is positioned at a position eccentric from a rotational center of a bearing housing, the bearing housing is rotated by the torque repulsive force applied to the second scroll, some of the torque repulsive force is converted into the sealing force against a sealing disturbing force.

    Abstract: In a scroll compressor, a discharge chamber is provided in an inner space of a back pressure chamber inner wall, a discharge port is provided inside the discharge chamber, a bypass hole is provided around the discharge port, and a communicating recess portion allowing the discharge chamber to communicate with the bypass hole is provided on an inner circumferential surface of the back pressure chamber inner wall forming the discharge chamber. Through this, the bypass hole may be easily configured in addition to the discharge port, thereby increasing an operation range of the compressor and suppressing overcompression.

    Abstract: A scroll compressor is provided, in which a balancing space may be formed on a sub frame to accommodate at least one balance weight, and an oil discharge hole may be formed on a main frame, thereby suppressing, all from being introduced into or remaining in the balancing space to minimize agitation loss due to oil agitation in the balancing space, and forming a thrust surface of the main frame adjacent to an axial center of the drive shaft to suppress axial leakage at a central portion of the orbiting scroll, reducing a size of the main frame to reduce a total weight of the compressor, facilitating a centering operation of the sub frame, and suppressing an outer diameter of the sub frame from being increased, thereby accomplishing miniaturization of the scroll compressor.
