Section and horizontal fuel-displaced section for being connected to oil inlet section, to better adapt to the structure of cylinder body 10, and can ensure the smooth of machine oil
Flowing.
On the basis of above-described embodiment, the fuel-displaced section of fuel feed pump 13 that can specifically include being connected to oil inlet section and detachable
It is connected to the spray bar 14 of fuel feed pump 13.Spray bar 14 is arranged to replaceable, starts motivation often with operating mode by matching
Air leakage may be selected suitable spray bar 14 and be installed, and flow direction driving rotor 15 is adjusted by this 14 diameter of spray bar
Oil flow rate, realize to drive rotor 15 rotating speed adjusting, gs-oil separator can be met to engine crankcase pressure
Control, make this section separative efficiency highest.
On the basis of any of the above-described embodiment, the outlet of separator oil outlet 20, cylinder body oil input channel 11 passes through oil return
Channel is communicated in cylinder body oil return opening 12, and the oil baffle 19 for blocking the oil droplet 17 that bent axle splashes can be equipped in drainback passage.
Since the splashing oil droplet 17 of crankshaft high-speed rotation can get rid of many machine oil into cylinder body oil return opening 12, cause to return at cylinder body oil return opening 12
Oil is not smooth, and by the setting of oil baffle 19, the oil droplet 17 that can be splashed to avoid bent axle by high speed rotation is through separator oil outlet 20
It is back in case 9.
On the basis of above-described embodiment, reinforcing rib can be connected between oil baffle 19 and drainback passage, to ensure to keep off
The intensity of oiled-plate method 19.
