Abstract
The utility model relates to a valve chamber cover of an engine, which comprises a valve chamber cover body (1) and a cover plate (2), wherein, a baffle plate is arranged on the valve chamber cover body (1); an oil return hole (3) is arranged on the cover plate (2); the valve chamber cover body (1) is matched with the cover plate (2) to form an oil-vapor separating space. The valve chamber cover is characterized in that a baffle plate (4) is arranged on the inner surface of the cover plate (2). Because of the adoption of the structure, the valve chamber cover has the advantages that both of the valve chamber cover body and the cover plate are cast with the baffle plates used for oil-vapor separation, so the oil vapor turns up and down in a vertical direction; after condensation, engine oil falls down by gravity, and can further collide and condense with the oil vapor; the collision and the condensation of the oil vapor with the engine oil and the engine oil with the baffle plates enhance the oil-vapor separation effect.
Description
Technical field:
The utility model relates to the motor car engine field, particularly a kind of engine valve chamber cover cap.
Background technique:
At present automotive engine valves chamber cover cap use the Oil-gas Separation space generally all baffle plates all with body casting together, real with cover plate baffle plate contact lid, oil gas is flowed around baffle plate in the horizontal direction, part oil gas in this design Oil-gas Separation space is not able to do in time and baffle plate collision has just flowed away, and causes machine oil not have fully cohesion, Oil-gas Separation insufficient.
The model utility content:
The utility model provides a kind of engine valve cover cap, makes oil gas and baffle plate, oil gas and machine oil collision to reach, and strengthens the purpose of oil gas separation.
A kind of engine valve chamber cover cap comprises the valve chamber cover body, and cover plate, cyclinder head cover cover and be provided with baffle plate, and cover plate is provided with spill port, and valve chamber cover body and cover plate cooperate formation Oil-gas Separation space; It is characterized in that: cover inner surface is provided with baffle plate.
A kind of engine valve chamber cover cap, it is characterized in that: the baffle plate on the described cover inner surface is vertically installed on the cover inner surface, and the branch setting such as becomes with baffle plate that cyclinder head cover covers, forms the Oil-gas Separation space of S shape.
A kind of engine valve chamber cover cap is owing to adopt said structure to have the following advantages: 1, all be cast with the baffle plate of separation oil and gas on valve chamber cover body and cover plate, oil gas is stirred down in vertical direction; 2, machine oil cohesion back falls because of action of gravity, can further collide, condense with oil gas; 3, oil gas separation has been strengthened in collision, the cohesion of oil gas and machine oil, machine oil and baffle plate two aspects.
Description of drawings:
Fig. 1 is a structural representation of the present utility model:
In Fig. 1: 1, valve chamber cover body; 2, cover plate; 3, spill port; 4, baffle plate.
Embodiment:
As shown in Figure 1: a kind of engine valve chamber cover cap, valve chamber cover body 1 cooperate formation Oil-gas Separation space with cover plate 2; All be provided with baffle plate 4 on cyclinder head cover interior surface 1 and the cover inner surface 2, the Oil-gas Separation space of S shape in separated space.Gas mixture enters after the Oil-gas Separation space, contacts with baffle plate 4 collisions.Machine oil cohesion back flows down along baffle plate 4, because of action of gravity is fallen, further cohesion, compiles and flows away from spill port 3 at cover plate 2; Gas moves on along the space between the baffle plate 4, until discharge.
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 the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
Claims (2)
1, a kind of engine valve chamber cover cap, comprise valve chamber cover body (1), cover plate (2), valve chamber cover (1) is provided with baffle plate (4), and cover plate (2) is provided with spill port (3), and valve chamber cover body (1) and cover plate (2) cooperate formation Oil-gas Separation space; It is characterized in that: cover plate (2) internal surface is provided with baffle plate (4).
2, a kind of engine valve according to claim 1 chamber cover cap, it is characterized in that: (2) lip-deep baffle plate (4) is vertically installed on cover plate (2) internal surface in the described cover plate, and the branch setting such as become with baffle plate (4) on the valve chamber cover (1), form the Oil-gas Separation space of S shape.
