Further, the scraper ring material of described first scraper ring group, the second scraper ring group and the 3rd scraper ring group is Cuprum alloy, and the seal ring material of ring assembly is the mixture of soft resin and hard resin.
Further, " O " RunddichtringO is provided with between described frizing ring seat and gear font.
Further, described first spill port and the second spill port stagger, and the aperture of the first spill port is slightly larger than the aperture of the second spill port.
Beneficial effect: compared with original technology, a kind of BOG of the present utility model reclaims compressor scraper ring box novel structure, reasonable in design, solve cylinder oil to leap up into the problem of crankcase, eliminate the hidden danger that crankcase lubrication is bad, extend the replacement cycle of lubricant oil, reduce cost, in addition rock gas can not be leapt up crankcase, and rock gas can not pollute crankcase lubricating oil, has stopped the danger of exploding.
