Preferably, an annular inclined surface for guiding the lubricating oil to the annular oil groove is arranged on the inner side of the oil scraping blade.
Preferably, in a longitudinal section of the ring body, the annular inclined surface forms an acute angle with the top surface of the ring body.
Preferably, a plurality of the flow guide channels are uniformly distributed on the inner circumference of the annular oil groove.
Preferably, the water conservancy diversion passageway is including vertical setting first passageway, the slope of annular oil groove below wear out downwards the second passageway and the intercommunication of ring body outer wall first passageway with the return bend passageway of second passageway, the upper end of first passageway with the annular oil groove is linked together.
Preferably, the diameter of the first passage is greater than the diameter of the second passage.
Preferably, the outer wall of the ring body is coated with an anti-wear agent. To sum up, the utility model discloses for its beneficial effect of prior art is:
the utility model discloses a be equipped with the frizing sword and improve the frizing effect, make oil flow back to the ring body surface from annular oil groove and water conservancy diversion passageway, make the interior lubricating oil of comparing of piston cavity even, prevent the lateral wall wearing and tearing and the oil reduction consumption of ring body, raise the efficiency, and simple structure, convenient to use.
