  • Lubrication of scroll compressor
    Patent number: 10641269
    Abstract: A scroll compressor is provided, including: a compression mechanism, a driving mechanism, a suction fitting and a lubrication system. The compression mechanism is adapted to compress working fluid and includes a movable scroll component, a fixed scroll component and a suction window, the working fluid flows into the compression mechanism via the suction window. The driving mechanism includes a driving shaft and is adapted to drive the compression mechanism. The working fluid flows into the scroll compressor via the suction fitting and then flow into the compression mechanism. The lubrication system includes a lubricant source and a compression mechanism oil supply device adapted to supply the lubricant to the compression mechanism from the lubricant source. The compression mechanism oil supply device has an oil supply passage and an outflow opening of the oil supply passage is located between an opening of the suction fitting and the suction window.
