<p><P>PROBLEM TO BE SOLVED: To provide a highly reliable screw compressor while solving the problem that a conventional technology greatly destabilizes an oil level fluctuation of an oil reservoir space with a gas swirl flow in an oil separation space to prohibit complete immersion of an oil strainer in oil and possibly cause the mixture of gas in the oil passing through the oil strainer, whereby insufficient oil supply occurs to hardly form an oil film on a bearing, resulting in a shorter life span of the bearing due to the wear and possible abnormal sounds of the compressor which may lose the reliability of the screw compressor. <P>SOLUTION: The compressor is configured to form a space in the lower part of a casing where lubricating oil is reserved, and to immerse the oil strainer in the lubricating oil. Herein, the oil strainer has a filtering part and an oil flow-out hole formed in one pipe member and partitioned with two cylindrical plate materials. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
