Abstract

The present invention proposes a structural unit ( 21 ) for arrangement on a hydraulic fluid tank of a jet engine having a vision device ( 23 ) and a sensor device ( 25 ), which can independently of one another determine a level of a hydraulic fluid present in a hydraulic fluid tank ( 1 ) when the structural unit ( 21 ) is arranged on a hydraulic fluid tank. A fastening device ( 27 ) is provided to fix the structural unit ( 21 ) on the hydraulic fluid tank.

First claim

What is claimed is:

1. A structural unit for arrangement on a hydraulic fluid tank of a jet engine, comprising:
a structural unit for arrangement on a hydraulic fluid tank of a jet engine,
a vision device and a sensor device mounted to the structural unit, which are configured independently of one another to determine a level of a hydraulic fluid present in the hydraulic fluid tank when the structural unit is arranged on the hydraulic fluid tank, the vision device and the sensor device being mounted to the structural unit,
a fastening device connecting the structural unit to the hydraulic fluid tank,
wherein the sensor device is mounted internally of the hydraulic fluid tank.

2. The structural unit in accordance with claim 1 , wherein the sensor device for determining the level of the hydraulic fluid is an inductively, capacitively or magnetically measuring sensor device.

3. The structural unit in accordance with claim 2 , wherein the sensor device is connected flexibly to the fastening device.

4. The structural unit in accordance with claim 3 , wherein a longitudinal axis of the sensor device includes an angle with an outer surface facing away from an interior of the hydraulic fluid tank or with an inner surface of the fastening device facing the interior of the hydraulic fluid tank when the structural unit is arranged on a hydraulic fluid tank.

5. The structural unit in accordance with claim 4 , wherein the vision device includes a transparent element by which a level of a hydraulic fluid present in the hydraulic fluid tank can be directly visually determined when the structural unit is connected to the hydraulic fluid tank.

6. The structural unit in accordance with claim 3 , wherein the vision device includes a transparent element by which a level of a hydraulic fluid present in the hydraulic fluid tank can be directly visually determined when the structural unit is connected to the hydraulic fluid tank.

7. The structural unit in accordance with claim 2 , wherein the sensor device is connected rigidly to the fastening device.

8. The structural unit in accordance with claim 7 , wherein a longitudinal axis of the sensor device includes an angle with an outer surface facing away from an interior of the hydraulic fluid tank or with an inner surface of the fastening device facing the interior of the hydraulic fluid tank when the structural unit is arranged on a hydraulic fluid tank.

9. The structural unit in accordance with claim 8 , wherein the vision device includes a transparent element by which a level of a hydraulic fluid present in the hydraulic fluid tank can be directly visually determined when the structural unit is connected to the hydraulic fluid tank.

10. The structural unit in accordance with claim 7 , wherein the vision device includes a transparent element by which a level of a hydraulic fluid present in the hydraulic fluid tank can be directly visually determined when the structural unit is connected to the hydraulic fluid tank.

11. The structural unit in accordance with claim 2 , wherein a longitudinal axis of the sensor device includes an angle with an outer surface facing away from an interior of the hydraulic fluid tank or with an inner surface of the fastening device facing the interior of the hydraulic fluid tank when the structural unit is arranged on a hydraulic fluid tank.

12. The structural unit in accordance with claim 11 , wherein the vision device includes a transparent element by which a level of a hydraulic fluid present in the hydraulic fluid tank can be directly visually determined when the structural unit is connected to the hydraulic fluid tank.

13. The structural unit in accordance with claim 2 , wherein the vision device includes a transparent element by which a level of a hydraulic fluid present in the hydraulic fluid tank can be directly visually determined when the structural unit is connected to the hydraulic fluid tank.

14. The structural unit in accordance with claim 1 , wherein a longitudinal axis of the sensor device includes an angle with an outer surface facing away from an interior of the hydraulic fluid tank or with an inner surface of the fastening device facing the interior of the hydraulic fluid tank when the structural unit is arranged on a hydraulic fluid tank.

15. The structural unit in accordance with claim 14 , wherein the vision device includes a transparent element by which a level of a hydraulic fluid present in the hydraulic fluid tank can be directly visually determined when the structural unit is connected to the hydraulic fluid tank.

16. The structural unit in accordance with claim 1 , wherein the fastening device is a flange.

17. The structural unit in accordance with claim 1 , wherein the vision device is made of fire-resistant material.

18. The structural unit in accordance with claim 1 , wherein the sensor device is connected flexibly to the fastening device.

19. The structural unit in accordance with claim 1 , wherein the sensor device is connected rigidly to the fastening device.

20. The structural unit in accordance with claim 1 , wherein the vision device includes a transparent element by which a level of a hydraulic fluid present in the hydraulic fluid tank can be directly visually determined when the structural unit is connected to the hydraulic fluid tank.
