Beschreibung
Zusammenfassung:	The utility model provides a magnesium alloy labyrinth valve mechanism cover subassembly, includes that valve mechanism cover, oil gas separation chamber, machine oil annotate hole, maze cover plate and valve mechanism cover and ventilate to taking over and chew, it has right angle rectilinear maze baffle and puts rectilinear maze baffle to one side still to generate in the oil gas separation chamber, the beneficial effects are that adopt magnesium alloy material replace aluminium alloy material make labyrinth valve mechanism cover subassembly weight loss 30%, can make the oil-gas separation effect better under the prerequisite that subtracts the weight, improve the energy transformation ratio of oil, reduce exhaust emission, compare with aluminum alloy valve mechanism cover shell facies, under the same condition of engine speed, the effectual noise that has reduced, the valve mechanism cover body combines maze cover plate and ventilation pipe, can make oil-gas separation more abundant, to use magnesium alloy material to carry out micro-arc oxidation formation ceramic membrane and serial protection film as the valve mechanism cover body of skeleton, and can make a dollar element obtain effectual protection and beautify the outward appearance effect.
