Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figures 1 to 6, the better embodiment of the utility model overturning-preventing forced breathing lubricating system includes having
The engine block 1 and cylinder head cover 2 of cylinder head, the cylinder head cover 2 are located on engine block 1.The engine block 1 has crankshaft room
11 and respiratory chamber 12, bent axle 3 and governor gear 4 are provided with the crankshaft room 11, the governor gear 4 is provided with oil-stirring plate 41,
Bent axle 3 drives governor gear 4 to rotate by series of drive, to stir the lubricating oil in crankshaft room 11, flies its lubricating oil
Camshaft lubrication, lower shake-changing arm and bearing are spilt, while lubricating oil portion is become into mist of oil.The engine block 1 be provided with
Cylinder head cover 2 connects first passage 14 and second channel 15, the first passage 14 connect with cylinder head cover 2, the second channel 15
Connected with the respiratory chamber 12.Mist of oil passage 21 is provided with the cylinder head cover 2, after mist of oil is from first passage 14 into cylinder head cover 2,
After the component lubrication in headkerchief lid 2, enter second channel 15 from mist of oil passage 21.Push rod in the rocker arm assembly is located at institute
State in first passage 14, without individually perforate again, be easy to technique to manufacture.It is provided between the respiratory chamber 12 and second channel 15
Control valve 16.The control valve 16 is type of respiration valve block, i.e., one end of valve block is fixed on engine block 1, valve block it is another
Limited location boss is held, valve block reverse opening can be avoided.The respiratory chamber 12 is connected by spill port 17 with crankshaft room 11, works as bent axle
