Oil separator
In an oil separator for separating oil from a fluid flow with a labyrinth-like flow guide which is formed essentially by baffle walls, at least one of the baffle walls in at least one partial area can be deformed in a manner similar to rubber.
1. A cylinder head cover comprising an elastomer part connected to a plastic cover part, the cover part being connected to an oil separation space wall, a nozzle plate provided with openings and positioned between the cover part and the oil separation space wall, and a pair of baffle walls positioned between the cover part and the oil separation space wall and forming a labyrinth flow guide, the baffle walls comprising a first baffle wall that is deformable and a second baffle wall, each of the openings possessing an axis that intersects the deformable first baffle wall.
2. The cylinder head cover according to claim 1 , wherein the first baffle wall is deformable to adapt a distance between the first and second baffle walls.
3. The cylinder head cover according to claim 2 , wherein the deformable baffle wall is made as an elastomer part.
4. The cylinder head cover according to claim 3 , wherein the first baffle wall is deformable to automatically adapt the distance between the first and second baffle walls by fluid flow.
5. The cylinder head cover according to claim 4 , wherein at least one projecting nub is connected securely to the deformable baffle wall and supports the deformable baffle wall when the deformable baffle wall is undeformed.
6. The cylinder head cover according to claim 5 , wherein a middle area of the deformable baffle wall is connected to the second baffle wall via a projecting connecting element.
7. The cylinder head cover according to claim 1 , wherein the deformable baffle wall is made as an elastomer part.
8. The cylinder head cover according to claim 1 , wherein the first baffle wall is deformable to automatically adapt the distance between the first and second baffle walls by fluid flow.
9. The cylinder head cover according to claim 1 , wherein at least one projecting nub is connected securely to the deformable baffle wall and supports the deformable baffle wall when the deformable baffle wall is undeformed.
10. The cylinder head cover according to claim 1 , wherein a middle area of the deformable baffle wall is connected to the second baffle wall via a projecting connecting element.
11. An oil separator for separating oil from a fluid flow in a separation space with a labyrinth flow guide, comprising first and second baffle walls forming the labyrinth flow guide, with at least a portion of the first baffle wall being deformable in a manner of rubber, the first baffle wall being positioned between the second baffle wall and a nozzle plate provided with a plurality of openings, the openings possessing an axis that intersects the deformable first baffle wall.
12. The oil separator according to claim 11 , wherein the deformable baffle wall is made for adapting the distance between the baffle walls.
13. The oil separator according to claim 12 , wherein the deformable baffle wall is made as an elastomer part.
14. The oil separator according to claim 13 , wherein the deformable baffle wall permits adaptation of the distance between the first and second baffle walls to occur automatically by the fluid flow.
15. The oil separator according to claim 14 , wherein the deformable baffle wall is made such that a pressure loss between entry and exit of the fluid flow on the oil separator is kept essentially constant.
16. The oil separator according to claim 15 , wherein at least one nub is connected securely to the deformable baffle wall, said nub supporting the deformable first baffle wall when the first baffle wall is essentially undeformed against the second baffle wall or a boundary of the oil separation space.
17. The oil separator according to claim 16 , wherein a middle area of the deformable baffle wall is connected to one of the baffle walls or the boundary of the oil separation space via projecting connecting elements.
18. The oil separator according to claim 17 , wherein the oil separator is a part of a cylinder head cover of an internal combustion engine.
19. A cylinder head cover comprising an elastomer part connected to a plastic cover part, the cover part being connected to an oil separation space wall, a nozzle plate provided with openings and positioned between the cover part and the oil separation space wall, and a pair of baffle walls positioned between the cover part and the oil separation space wall and forming a labyrinth flow guide, the baffle walls comprising a first baffle wall that is deformable and a second baffle wall,
wherein at least the first baffle wall extends over the openings in the nozzle plate,
each of the openings possessing an axis that intersects the deformable first baffle wall.
