Abstract
The utility model relates to an engine filter core type crankcase ventilation maze structure which comprises a maze casing (1) and a lower cover plate (3). The maze structure is formed by blocking plates between the maze casing (1) and the lower cover plate (3). An air inlet (4) and an air outlet (5) are communicated through the maze structure. The engine filter core type crankcase ventilation maze structure is characterized in that an oil-gas separation filter core assembly (2) is arranged in the maze structure. Due to the filter function of the filter core assembly, the engine filter core type crankcase ventilation maze structure can well separate small-sized oil drops in gas, greatly reduces machine oil carrying amount of crankcase gas passing through a maze to enter a gas inlet branch pipe, reduces carbon deposition of an engine and prolongs the maintenance period of the engine and the service life of the engine.
Description
Technical field
The utility model relates to a kind of motor filer element type crankcase ventilation labyrinth structure, especially relates to a kind of motor filer element type crankcase ventilation labyrinth structure with filtering effect.
Background technique
Existing engine crankshaft ventilation system labyrinth structure is mainly take baffle arrangement as main, by design labyrinth baffle arrangement, do not affecting under the bent prerequisite of pressing, the distance that crank case gases is flowed in the labyrinth is maximum, airflow strikes on baffle plate because long mobile decline apart from gas temperature strikes that the machine oil condensation in the gas is attached on the baffle plate on the baffle plate, thereby reach the effect of Oil-gas Separation, but this mode can not be separated the machine oil in the crank case gases to greatest extent, still have sub-fraction and enter into intake manifold with crank case gases, behind valve, form carbon distribution.
Summary of the invention
The utility model has designed a kind of motor filer element type crankcase ventilation labyrinth structure, the technical problem of its solution is that existing engine crankshaft ventilation system labyrinth structure is insufficient to Oil-gas Separation, still have sub-fraction and enter into intake manifold with crank case gases, behind valve, form carbon distribution.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of motor filer element type crankcase ventilation labyrinth structure, comprise labyrinth housing (1) and lower cover plate (3), between labyrinth housing (1) and lower cover plate (3), form labyrinth structure by baffle plate, suction port (4) and air outlet (5) are communicated with by described labyrinth structure, it is characterized in that: the filter core assembly (2) that an Oil-gas Separation is set in described labyrinth structure.
Further, described filter core assembly (2) is positioned at the side near air outlet (5).
Further, described filter core assembly (2) comprises a housing, and filter core (22) is arranged in the housing, offers vent (21) at the sidewall of housing, offers spill port (23) in the bottom of housing.
Further, be provided with accumulator tank at lower cover plate (3), described accumulator tank is collected the machine oil that described filter core assembly (2) is separated.
Further, be provided with spill port bottom the described accumulator tank.
This motor filer element type crankcase ventilation labyrinth structure has following beneficial effect in comparing with conventional engines filer element type crankcase ventilation labyrinth structure:
(1) the better divided gas flow small-medium size oil droplet of the filtration of the utility model filter core assembly energy, crank case gases engine oil carrying quantity through entering into behind the labyrinth in the intake manifold is reduced greatly, the carbon distribution that reduces motor produces, and prolongs engine maintenance cycle and engine life.
(2) the utility model has improved filtering effect owing to being provided with filter core assembly, thereby can greatly reduce the labyrinth of labyrinth interior panelling, makes Mold Making simple, saves cost.

Embodiment
Below in conjunction with Fig. 1 to and Fig. 3, the utility model is described further:
As shown in Figure 1, this labyrinth structure mainly is divided into three bulks, is respectively labyrinth housing 1, filter core assembly 2, lower cover plate 3.Filter core assembly 2 is arranged in the labyrinth.
As shown in Figure 2, crank case gases enters in the labyrinth housing 1 by the suction port on the lower cover plate 3, after filtration 5 outflows from the air outlet after the filtration of core assembly 2.The machine oil that filters out of core assembly 2 is under self gravitation and stream pressure effect after filtration, and machine oil flow back into by the spill port on the filter core assembly 2 in the accumulator tank of lower cover plate 3, gets back in the motor by the spill port on the accumulator tank more afterwards.
In addition, filter core assembly 2 is positioned at the side near air outlet 5, and its purpose is: oil gas is higher than the speed of air outlet 5 in the speed of suction port 4, filter core assembly 2 is arranged on a side of close air outlet 5, so that the oil gas speed of core assembly 2 is lower after filtration, more help Oil-gas Separation.
As shown in Figure 2, filter core assembly 2 comprises a housing, and filter core 22 is arranged in the housing, offers vent 21 at the sidewall of housing, offers spill port 23 in the bottom of housing.Filter core 22 is foam bodies of a kind of similar sponge.The machine oil of separating in the filter core 22 is got back in the accumulator tank of cover plate by the gravity of self and the pressure flow of the filter core gas of flowing through, and flow back in the motor by spill port.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all in protection domain of the present utility model.
