涡旋压缩机
摘要：
本发明提供一种涡旋压缩机，其通过优化运转中的润滑油的缸内油循环率来提高压缩效率。在台阶状的涡旋压缩机中，将被吸入在涡旋压缩机内与冷媒一起循环的润滑油的缸内油循环率设定在1％以上且10％以下的范围内。
摘要（英）：

A scroll compressor in which the degree of in-cylinder lubricating-oil circulation during operation is optimized to improve compression efficiency. It is a stepped scroll compressor in which the degree of in-cylinder circulation of a lubricating oil which is sucked in the scroll compressor and circulates together with a refrigerant is regulated to 1-10%.
