    • A scroll compressor is provided, in which at least one bypass hole that bypass a portion of a refrigerant before the refrigerant is discharged through a discharge hole is formed at a position where a bypass section that bypasses the refrigerant through the at least one bypass hole overlaps a discharge section that discharges the refrigerant through the discharge hole. The at least one bypass hole is formed at a position where a wrap volume ratio (Vs/Vd), which is a ratio of a suction volume (Vs) with respect to a discharge volume (Vd) in a compression chamber, is within the range of about 1.8˜2.2. With this configuration, over-compression of refrigerant may be prevented in a low speed driving mode, and efficiency of the compressor may be enhanced in the low speed driving mode and under a low load condition.
    • 提供了一种涡旋式压缩机,其中在通过所述至少一个旁通孔旁路制冷剂的旁通部分的位置处形成有至少一个在制冷剂通过排出孔排出之前绕过制冷剂的一部分的旁通孔重叠 排出部,其通过排出孔排出制冷剂。 至少一个旁通孔形成在作为吸入容积(Vs)相对于压缩室中的排出容积(Vd)的比率的卷绕体积比(Vs / Vd)在 范围约1.8〜2.2。 利用这种结构,可以在低速驱动模式下防止制冷剂的过度压缩,并且在低速驱动模式和低负载条件下可以提高压缩机的效率。

    • A compressor having a lower frame and a method of manufacturing the same are disclosed. The compressor may include a cylindrical shell, a rotational shaft rotatably mounted in the cylindrical shell, a rotor and a stator that rotates the rotational shaft, a compression device driven by the rotational shaft, a lower bearing configured to rotatably support one side of the rotational shaft, a lower frame configured to support the lower bearing, the lower frame being configured to be press-fitted into a lower end portion of the cylindrical shell, and a base configured to seal the lower end portion of the cylindrical shell. The lower frame may include a main body configured to be press-fitted onto an inner circumferential surface of the cylindrical shell and a flange that extends from the main body, the flange being configured to limit a press-fit depth by contacting the lower end portion of the cylindrical shell.
    • 公开了一种具有下框架的压缩机及其制造方法。 压缩机可以包括圆筒形壳体,可旋转地安装在圆柱形壳体中的旋转轴,转子和使旋转轴旋转的定子,由旋转轴驱动的压缩装置,下轴承,其构造成可旋转地支撑转动的一侧 轴,构造成支撑下轴承的下框架,下框架被构造成压配合到圆柱形壳体的下端部分中,以及基部,其构造成密封圆柱形壳体的下端部分。 下框架可以包括构造成压配合到圆筒形壳体的内圆周表面上的主体和从主体延伸的凸缘,凸缘构造成通过使下端部分接触来限制压配合深度 的圆柱形外壳。
