    Abstract: A motor-operated compressor includes a casing having an inner space in which a driving motor, an orbiting scroll and a fixed scroll are accommodated, and a controller provided outside the casing. The casing includes an intake hole formed at a side adjacent to the controller and an exhaust hole formed at a side adjacent to the fixed scroll on the basis of the driving motor. The casing includes a communication passage formed between the casing and a stator of the driving motor, such that a refrigerant introduced into the inner space through the intake hole is introduced into the suction chamber through the driving motor. A back pressure space supporting the orbiting scroll is sealed by oil. The stator has teeth on its inner circumferential surface and protrusions on its outer circumferential surface, each protrusion being located within a width range of each tooth.

    Abstract: Disclosed is a scroll compressor with a refrigerant discharge flow passage and an oil recovery flow passage separated from each other to improve efficiency and reliability of the compressor. The scroll compressor includes a flow passage separation unit configured to separate an intermediate space between a drive unit and a compression unit into an inner space communicating with the refrigerant flow passage and an outer space communicating with the oil flow passage to separate the refrigerant discharge path from the oil recovery path. Accordingly, the present invention may prevent the oil from being mixed with the discharged refrigerant, thereby reducing an oil discharge amount.

    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。
