    Abstract: A scroll compressor includes: an orbiting scroll (33) having an orbiting wrap (332), and which performs an orbiting motion; and a fixed scroll (32) having a fixed wrap (323) to form a compression chamber (V) of a suction chamber, an intermediate pressure chamber and a discharge chamber, by being engaged with the orbiting wrap (332), wherein a wrap thickness of the fixed wrap (323) is greater than that of the orbiting wrap (332) within a range which forms the suction chamber (Vs).
    With such a configuration, even if the fixed scroll or the orbiting scroll is thermally-expanded, a transformation of the fixed wrap at a suction side may be prevented. This may prevent a gap between the fixed wrap and the orbiting wrap at an opposite side to the suction side, thereby enhancing compression efficiency.

    Abstract translation: 涡旋式压缩机包括：具有绕动涡卷（332）并且进行绕动运动的绕动涡卷（33） 和具有通过与所述绕动涡卷（332）接合而形成抽吸室，中间压力室和排放室的压缩室（V）的固定涡卷（323）的固定涡旋件（32），其中， 在形成吸入室（Vs）的范围内，固定涡卷（323）的厚度大于绕动涡卷（332）的厚度。 利用这样的构造，即使固定涡卷或绕动涡卷热膨胀，也可以防止固定涡卷在吸入侧的变形。 这可以防止固定涡卷和绕动涡卷之间在与抽吸侧相对的一侧上的间隙，从而提高压缩效率。

    Abstract: Scroll compressor including
    a casing (110);
    a driving motor (120) comprised inside the casing (110);
    an orbiting scroll (150);
    a fixed scroll (140) through which a suction port (1421) extends from an outer circumferential surface of the fixed scroll (140)
    a refrigerant suction pipe (115) penetrating through the casing (110) and inserted into an inlet end of the suction port (1421),
    whereby a reinforcing unit (145) is provided between an outlet end (1421b) of a suction port (1421) and an outer circumferential surface of the fixed wrap (144) facing the outlet end of the suction port. The reinforcing unit (145) overlaps a part of the outlet end (1421b) of the suction port (1421) in a radial direction when being projected in an axial direction.

    Abstract: A compressor is disclosed, which enables effective and active oil supply required for lubrication of a compression portion for compressing a refrigerant. The compressor comprises a case; a driving motor including a stator provided at an inner side of the case and a rotor rotatably provided at an inner side in a radius direction of the stator; a centrifugation space defined inside the case by a downstream side of the driving motor and the case, enabling centrifugation of a compressed refrigerant and a lubricant oil; a discharge pipe provided in the case, discharging the refrigerant inside the centrifugation space to the outside of the case; a rotary shaft rotated by being coupled to the rotor and provided with an oil supply path; a compression portion provided at an upstream side of the driving motor, compressing the refrigerant through rotation of the rotary shaft; a pump assembly provided below the rotary shaft, pumping oil by being rotated in a single body with the rotary shaft; and an oil pickup forming an oil supply path between the pump assembly and a low oil space formed inside the case.

    Abstract: Disclosed herein is a scroll compressor including a casing, a drive motor arranged in the casing, a shaft coupled to the drive motor, a main frame arranged under the drive motor, a fixed scroll arranged under the main frame, an orbiting scroll arranged between the main frame and the fixed scroll and engaged with the fixed scroll to form a compression chamber with the shaft eccentrically coupled to the orbiting scroll, a discharge cover coupled to the fixed scroll to form a closed space, a discharge port formed in the fixed scroll to connect the compression chamber and the closed space, and a discharge hole passing through the main frame and the fixed scroll, wherein an inlet and an inner portion of the discharge hole have different cross-sectional areas. The scroll compressor can reduce the noise caused by movement of the refrigerant by improving the structure of the discharge holes.
