Abstract
The utility model discloses an oil-gas separator for an engine, which comprises an upper end cover (1), a housing (2) and a stopper (4), wherein the upper end cover (1) is connected with the housing (2); and a guide plate (5), of which one end close to the upper end cover (1) is closed and the other end far away from the upper end cover (1) is open, is arranged on the upper end cover (1). By adopting the technical scheme, the oil-gas separator for the engine provided by the utility model has the advantages of simple structure, low cost and easy process realization, and meanwhile improves the oil-gas separation efficiency; and moreover, the guide plate and the upper cover are integrated, so that the intensity of the guide plate is increased.
Description
Technical field
The utility model relates to engine crankshaft ventilated box system, and more particularly, the utility model relates to a kind of oil-gas separating device for engine.
Background technique
The major function of engine crankshaft ventilation system makes the control crankcase pressure, prevent the oil sealing leakage of oil, usually adopt the Oil-gas Separation measure, reduce consumption of lubricating oil, improve burning, water vapour and sour gas that burning produces are drained, both prevented the rotten of machine oil, prevented that also the acidic liquid that produces from corroding component, at present, the measure of Oil-gas Separation is a lot, and labyrinth structure is arranged, cyclone type oil-gas separator, spiral deaerator, the filer element type deaerator, electrostatic deaerator, centrifugal oil-air separator or the like, but above-mentioned measure has the following disadvantages:
1, the maintenance of filer element type deaerator is loaded down with trivial details, the maintenance cost height;
2, the manufacture cost height of electrostatic deaerator, centrifugal oil-air separator;
3, there are problems such as oil gas separation is not good in labyrinth structure, cyclone type oil-gas separator, spiral deaerator.
The model utility content
Problem to be solved in the utility model provides a kind of oil-gas separating device for engine, its objective is simple in structure, cost is low, technology is easy to realize, improves Oil-gas Separation efficient.
To achieve these goals, the technological scheme taked of the utility model is:
This oil-gas separating device for engine provided by the utility model, a kind of oil-gas separating device for engine, comprise upper end cap, housing and obstruction, described upper end cap is connected with described housing, described upper end cap is provided with close described upper end cap one an end sealing, away from the unlimited helical guide plate of described upper end cap one end.
Described guide plate and described upper end cap are one.
Be provided with non-return valve at opening near described guide plate.
Adopt technique scheme, this oil-gas separating device for engine that the utility model provides is simple in structure, and cost is low, and technology is easy to realize that also improved Oil-gas Separation efficient simultaneously, guide plate and upper end cap are one, have increased the intensity of guide plate.

Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, this is a kind of oil-gas separating device for engine, comprises upper end cap 1, housing 2 and stops up 4, described upper end cap 1 is connected with described housing 2.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, solve the loaded down with trivial details difficult problem of structure, reduce cost, improve Oil-gas Separation efficient, the technological scheme that the utility model is taked is:
As shown in Figures 1 to 4, this oil-gas separating device for engine provided by the utility model, described upper end cap 1 are provided with one near the sealing of described upper end cap 1 one ends, the helical guide plate 5 that opens wide away from described upper end cap 1 one ends.
Adopt technique scheme; Utilize oil droplet particulate when rotation centrifugal force and realize Oil-gas Separation at the adhesive force on described deflector 5 surfaces; Distribute to change the centrifugal force that the oil droplet particulate is subjected to by the velocity field that changes gs-oil separator inside; Improved oil-gas separation efficiency; Oil droplet particulate in the gaseous mixture has also improved oil-gas separation efficiency at the adhesive force of described baffle surface simultaneously; Described deflector one end seals that an end opens wide can be when improving oil-gas separation efficiency; Also guaranteed the smoothness of separator oil return
As shown in Figures 1 to 4, described guide plate 5 is an one with described upper end cap 1.
Adopt said structure, described upper end cap 1 and described guide plate 5 adopt integrated mode, have increased the intensity of described guide plate 5, are convenient to the demoulding.
As shown in Figures 1 to 4, be provided with non-return valve 3 at opening near described guide plate 5.
Adopt said structure, be provided with non-return valve 3 at the opening near described guide plate 5, described non-return valve 3 can effectively prevent the machine oil suck-back at crankcase ventilation system return tube place, improves the crankcase ventilation system reliability.
The technological scheme that the utility model adopted compared with prior art, has tangible difference, possessed outstanding substantial characteristics, and obtained remarkable progress technically, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicability.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
