Abstract:
1. A compressor comprising: a hermetic container; a stator secured within the hermetic container, that generates a rotating electromagnetic field; a cylinder type rotor that is rotated within the stator by the rotating electromagnetic field of the stator and defines a compression chamber within the cylinder type rotor; a roller that rotates within the compression chamber of the cylinder type rotor by a rotational force transferred from the cylinder type rotor and compresses a refrigerant during rotation; a rotational shaft that is integrally formed with the roller and protrudes from a side of the roller in an axial direction of the roller; a vane that divides the compression chamber into a suction region, into which the refrigerant is sucked, and a compression region, in and from which the refrigerant is compressed and discharged, wherein the vane transfers the rotational force from the cylinder type rotor to the roller a first cover and a second cover that are joined to the cylinder type rotor in an axial direction of the cylinder type rotor and rotate together with the cylinder type rotor, wherein the compression chamber in which the refrigerant is compressed is defined between the cylinder type rotor, the roller, the first cover, and the second cover, wherein the first cover has a surface that faces and covers the roller, the surface including a suction port through which the refrigerant is suctioned into the compression chamber, and wherein the rotational shaft extends through the second cover; and a mechanical seal installed between the hermetic container and the first covers wherein the mechanical seal rotatably supports the first cover.
