Abstract
The utility model discloses a cylinder cover oil -gas separating device, cover and install the baffle in the cylinder cap cover including the cylinder cap, first oil -recovery tank, oil gas entry, oil baffle maze, second oil -recovery tank, first oil baffle, second oil baffle and third oil baffle, fender line of oils zygostyle, fourth oil baffle and third oil -recovery tank have been arranged on the baffle after to in proper order in the past, the oil gas entry is domatic for the slope, and oil gas is in the oil -gas separation passageway that the oil gas entry got into the baffle and the cylinder cap cover encloses, interior the opening of first, two, three oil -recovery tanks has the oil gallery, relative with oil gas entry one side, the cylinder cap in oil -gas separation passageway rear end covers to open and has the gas outlet. Can effectively improve the oil -gas separation effect, enable crankcase pressure again and keep at reasonable within range.
Description
Technical field
The utility model belongs to technical field of automobile engine, is specifically related to a kind of cylinder cover oil-gas separating device.
Background technology
At present, what engine used is mostly labyrinth type cylinder cap cover, owing to oil weir design in cylinder cap cover is often reasonable not, causes oil gas separation not obvious, and a large amount of oil gas is discharged in air by venting hole, serious environment pollution.
For improving oil gas separation, in industry, more oil weir is set in cylinder cap cover of being everlasting, increases oil weir and crankcase pressure then can be made to increase, affect crankcase use properties and life-span.
Practical novel content
The utility model aims to provide one and effectively improves oil gas separation, and crankcase pressure can be made again to remain on the cylinder cover oil-gas separating device of zone of reasonableness.
For this reason, the technical scheme that the utility model adopts is: a kind of cylinder cover oil-gas separating device, the baffle plate comprising cylinder cap cover and be arranged in cylinder cap cover, described baffle plate is furnished with the first return chute, oil gas entrance, oil weir labyrinth, the 2nd return chute, the first oil weir, second gear oil plate and third gear oil plate, gear oil coupled column, fourth gear oil plate, the 3rd return chute from front to back successively; Described oil gas entrance is tilt domatic, and oil gas is in the gas-oil separation passage that oil gas entrance enters baffle plate and cylinder cap cover surrounds; Described first oil weir is just to the opening in oil weir labyrinth; It is arranged side by side thus forms oil gas passageway to described second gear oil plate and third gear oil plate interval; Described gear oil coupled column is spaced by some columns and forms, and just to oil gas passageway; Described fourth gear oil plate is positioned at gear oil coupled column right astern; Oil return hole is had in first, second and third return chute described; Relative with oil gas inlet side, the cylinder cap cover of gas-oil separation passage rear end has pneumatic outlet.
Further, described oil weir labyrinth is made up of two pieces of oil weirs, the setting and stagger in left and right; Described gear oil coupled column is made up of side by side five root posts; Integral layout is more reasonable, and oil gas separation is more remarkable.
On the basis of such scheme, the described baffle plate back side is provided with stiffening web; Increase baffle plate intensity.
The beneficial effects of the utility model are: being arranged by the combination of oil weir and gear oil coupled column, after oil gas clashes into after leading and accelerating, separation efficiency is higher; The reasonable Arrangement of oil groove and oil return hole, makes separated oil can flow back to crankcase by oil return hole as soon as possible, in order to avoid oil return speed amasss in gas-oil separation passage slowly by the extremely outlet of air-flow band; Ensure crankcase pressure in the reasonable scope.

Embodiment
Below by embodiment and by reference to the accompanying drawings, the utility model is described in further detail:
As shown in Figures 1 to 3, a kind of cylinder cover oil-gas separating device, form primarily of cylinder cap cover a and the baffle plate b being arranged in cylinder cap cover a, baffle plate b is furnished with the first return chute 1, oil gas entrance 2, oil weir labyrinth 3, the 2nd return chute 4, first oil weir 5, second gear oil plate 6 and third gear oil plate 7, gear oil coupled column 8, fourth gear oily plate 9, the 3rd return chute 10 from front to back successively; Oil gas entrance 2 is domatic for what tilt; First oil weir 5 is just to the opening in oil weir labyrinth 3; It is arranged side by side thus forms oil gas passageway to second gear oil plate 6 and third gear oil plate 7 interval; Gear oil coupled column 8 is spaced by some columns and forms, and just to oil gas passageway; Fourth gear oil plate 9 is positioned at gear oil coupled column 8 right astern; Oil return hole c is all had in first return chute 1, the 2nd return chute 4, the 3rd return chute 10; Relative with oil gas entrance 2 side, the cylinder cap cover a of gas-oil separation passage rear end has pneumatic outlet 11. Preferably, oil weir labyrinth 3 is made up of two pieces of oil weirs, the setting and stagger in left and right, and gear oil coupled column 8 is made up of side by side five root posts, and the back side of baffle plate b is provided with stiffening web.
Oil gas enters in the gas-oil separation passage that baffle plate b and cylinder cap cover a surrounds through oil gas entrance 2, through oil weir labyrinth 3, first oil weir 5, then gear oil coupled column 8 is entered from the oil gas passageway in the middle of second gear oil plate 6 and third gear oil plate 7, arrive fourth gear oil plate 9, machine oil remains in gas-oil separation passage through collision rift, collected by the first return chute 1, the 2nd return chute 4, the 3rd return chute 10, finally flowing back into crankcase from oil return hole c, gas is then discharged by the pneumatic outlet 11 on cylinder cap cover a.
