and cam of bent axle, makes machine oil atomization expand lubricated scope and improve lubrication effect.Machine oil in sump is inhaled in machine oil pipe by the filtration of machine oil filter core, on sidewall due to cam chamber, oil inlet hole is set, therefore, the machine oil in machine oil pipe enters in cam chamber by oil inlet hole, makes machine oil enter cam chamber from sump by oil inlet hole, machine oil pipe and machine oil filter core.The machine oil reclaiming in crankcase is pressed in the valve of crankcase bottom near a side of cam chamber by the descending pressure that wrist pin produced, then enters oil pipe lubricated to saw chain by valve.The mounting groove degree of depth that crankcase outer surface arranges near oil pipe place is more than or equal to the diameter of oil pipe, can be fixed oil pipe, mounting groove is provided with near oil pipe opening the oil storage tank that the degree of depth is less than mounting groove, the carrying out that oil storage tank not only can be discharged the opening of oil pipe storage to a certain degree, and oil storage tank can carry out reverse resilience to the machine oil of discharging, the machine oil that the machine oil of resilience is discharged oil pipe is realized collision, buffering, slow down oil pipe and discharge speed and the discharge capacity of machine oil, in lubricated to saw chain, play effect fuel-efficient, fuel-economizing.Cam chamber bottom is provided with the return opening being connected with crankcase, can make the residual machine oil of the receipts oilhole that cam chamber bottom surface fails to enter bent axle reclaim, and can directly enter in crankcase by return opening, avoids that cam chamber is inner piles up residual machine oil.
