Abstract
PURPOSE:To prevent bad influence to engine as well as reduce the consumption of lubricating oil by providing an escape hole in the land portion between oil ring and piston ring groove. CONSTITUTION:The escape hole 13 is provided in the land portion 10 between the oil ring groove 5 and the piston ring groove 3 just above the oil ring 6. Thus, even if a gas pressure is produced at the land protion 10 during slow-speed rotation time of engine, gas can be promptly exhausted through the escape hole 13 and therefore the check valve effect of oil ring can be maintained. Also, even during high-speed rotation time, lubricating oil coming into the land portion 10 can be promptly exhausted from the escape hole 13, permitting the reduction of lubricating oil consumption.
