Abstract

A device for passing lubricant out of a lubricant collecting container to a lubricant pump, in particular for an oil circuit of an internal combustion engine. The device including a lubricant intake pipe and a sedimentation container, which is connected fluidically to the lubricant intake pipe.

First claim

What is claimed is:

1. A device for passing lubricant out of a lubricant collecting container of a machine or hydraulic system to a lubricant pump comprising:
a lubricant intake pipe, and
a sedimentation container, which is connected fluidically to the lubricant intake pipe, wherein the sedimentation container has a turbulator configured to increase a sedimentation rate of contaminants in the lubricant, the turbulator arranged in the region of an inlet opening of the sedimentation container.

2. The device according to claim 1 , wherein the lubricant intake pipe:
a) has a first pipe segment, by means of which lubricant can be fed from the lubricant collecting container to an inlet opening of the sedimentation container, and
b) has a second pipe segment, by means of which lubricant emerging from an outlet opening of the sedimentation container can be delivered in the direction of the lubricant pump.

3. The device according to claim 1 , wherein the sedimentation container has a drain connection arranged in the bottom region.

4. The device according to claim 1 , wherein the sedimentation container has a filling connection or an inspection connection.

5. The device according to claim 1 , wherein the sedimentation container forms a segment of the lubricant intake pipe which has an enlarged cross section.

6. The device according to claim 1 , wherein the sedimentation container is embodied as a separate component, which is connected fluidically to the lubricant intake pipe.

7. The device according to claim 1 , wherein the lubricant intake pipe has an intake cage at the inlet end thereof.

8. The device according to claim 1 , further comprising the lubricant collecting container.

9. The device according to claim 8 , wherein the sedimentation container is integrated into the lubricant collecting container or is encased by the latter; or
the sedimentation container is arranged outside the lubricant collecting container.

10. The device according to claim 8 , wherein the lubricant collecting container is an oil pan of an internal combustion engine.

11. The device according to claim 1 , further comprising the lubricant pump, in particular of an oil circuit of an internal combustion engine.

12. The device according to claim 11 , wherein the lubricant pump is designed to draw in lubricant from an oil pan via the lubricant intake pipe and the sedimentation container and to feed it to consuming units.

13. The device according to claim 1 , the machine or hydraulic system is an internal combustion engine.

14. The device according to claim 1 , wherein the device is a component of an oil circuit of an internal combustion engine.

15. A motor vehicle comprising:
a device for passing lubricant out of a lubricant collecting container to a lubricant pump, the device including,
a lubricant intake pipe, and
a sedimentation container, which is connected fluidically to the lubricant intake pipe, wherein the sedimentation container has a turbulator configured to increase a sedimentation rate of contaminants in the lubricant, the turbulator arranged in the region of an inlet opening of the sedimentation container.
