Abstract

In order to improve an oil separator unit, in particular an oil separator unit provided for vehicle drives, comprising an oil separator housing with a drainage system and a check valve unit which is formed from a valve seat and a valve element which comprises a valve member of an umbrella-like design and consisting of an elastomer, in such a manner that it can be produced as inexpensively as possible, on the one hand, and, on the other hand, the wear on the valve element is, however, considerably reduced or occurs to as low a degree as possible, it is suggested that the valve member of the valve element be held on an insert part and that the insert part be insertable, for its part, into an insert part receptacle in a valve housing.

First claim

The invention claimed is:

1. An oil separator unit provided for vehicle drives, comprising an oil separator housing with an oil collecting device, a drainage system and a check valve unit comprising a valve housing, a valve seat and a valve element, said valve element comprising a valve member of an umbrella-shaped design, having a stem connected thereto, and consisting of an elastomer, the valve member of the valve element is connected to an insert part by the stem extending through and guided by an opening in the insert part, the valve element and stem are movable as a whole, relative to the insert part and the valve seat, between a closed position and an open position, and wherein the insert part is, for its part, inserted into an insert part receptacle provided in the valve housing.

2. Oil separator unit as defined in claim 1 , wherein the insert part receptacle is integrally formed on the valve housing in one piece.

3. Oil separator unit as defined in claim 1 , wherein the insert part is designed as a one-piece part.

4. Oil separator unit as defined in claim 1 , wherein the insert part is held in the insert part receptacle in a form locking manner.

5. Oil separator unit as defined in claim 4 , wherein the insert part is lockable in the insert part receptacle.

6. Oil separator unit as defined in claim 1 , wherein the insert part is fixed in place in the insert part receptacle in a materially locking manner.

7. Oil separator unit as defined in claim 6 , wherein the insert part is glued to the insert part receptacle.

8. Oil separator unit as defined in claim 6 , wherein the insert part is welded to the insert part receptacle.

9. Oil separator unit as defined in claim 1 , wherein the insert part has at least one opening for oil.

10. Oil separator unit as defined in claim 1 , wherein the valve member is held directly on the insert part.

11. Oil separator unit as defined in claim 10 , wherein the valve member is connected securely to the insert part.

12. Oil separator unit as defined in claim 1 , wherein the valve member is provided with a holding attachment of the valve element, said holding attachment comprising the stem.

13. Oil separator unit as defined in claim 12 , wherein the holding attachment is integrally formed on the valve member in one piece.

14. Oil separator unit as defined in claim 1 , wherein the valve member is guided for movement between the closed position and the open position.

15. Oil separator unit as defined in claim 14 , wherein the valve member is guided without any canting.

16. Oil separator unit as defined in claim 1 , wherein the insert part accommodates the valve element with burr-free surfaces.

17. Oil separator unit as defined in claim 1 , wherein the insert part accommodates the valve element with machined surfaces.

18. Oil separator unit as defined in claim 1 , wherein the insert part abuts on the valve element with surfaces merging into one another with radii >0.2 millimeters.

19. Oil separator unit as defined in claim 1 , wherein the insert part is formed from a plastic material free of reinforcing fibers.

20. Oil separator unit as defined in claim 1 , wherein the insert part has a ring member for accommodating the valve element.

21. Oil separator unit as defined in claim 20 , wherein the ring member has a rounded ring inner side.

22. Oil separator unit as defined in claim 1 , wherein the insert part has a holding sleeve.

23. Oil separator unit as defined in claim 22 , wherein the holding sleeve abuts on the valve element with a rounded supporting bead.

24. Oil separator unit as defined in claim 1 , wherein the insert part receptacle accommodates the insert part at least partially.

25. Oil separator unit as defined in claim 1 , wherein the insert part receptacle accommodates the insert part completely.

26. Oil separator unit as defined in claim 1 , wherein the valve element is arranged outside the insert part receptacle.

27. Oil separator unit as defined in claim 1 , wherein the insert part receptacle accommodates the valve element.

28. Oil separator unit as defined in claim 1 , wherein the valve element is arranged in a space formed between the insert part and the insert part receptacle.

29. Oil separator unit as defined in claim 1 , wherein the valve seat is formed on the valve housing.

30. Oil separator unit as defined in claim 1 , wherein the valve seat is formed on the insert part.

31. Oil separator unit as defined in claim 1 , wherein the oil separator housing and/or the valve housing is formed from a fiber-reinforced plastic material.

32. Oil separator unit as defined in claim 1 , wherein the insert part is made from a different material than the insert part receptacle in the valve housing.

33. Oil separator unit as defined in claim 32 , wherein the insert part is made from a plastic material free of reinforcing fibers, and the insert part receptacle in the valve housing is made from a plastic material with reinforcing fibers.

34. Oil separator unit as defined in claim 1 , wherein the insert part is tubular.

35. Oil separator unit as defined in claim 34 , wherein the insert part is disposed within an opening in the insert part receptacle.

36. Oil separator unit as defined in claim 34 , wherein the insert part completely encloses more than half of the length of the valve stem.

37. Oil separator unit as defined in claim 1 , wherein the valve seat is formed from a portion of the valve housing.
