The present invention relates to an oil scraper and a compressor with such an oil scraper. The traditional oil scraping device with split ring to avoid leakage, and especially in having a sharp scraping edge metal scraper ring design, oil scraping device on the piston rod surface scraping, which may damage the piston rod. In order to eliminate these problems and proposes an oil scraping device, wherein, the oil scraper ring (2) and a locking ring (3) radial internal circumference (6, 7) to form a radial internal common oil scraping surface (10), and the locking ring (3) or in scraping oil ring (2) is arranged on the guide surface (8), the introduction of surface is connected with the oil scraping surface (10) and (10) surface oil scraping radially outwardly inclined at an angle (alpha), the preferred angle between 2 DEG and 15 DEG.
