Abstract

In the case of a storage vessel of cryogenic gas or cryogenic compressed gas, particularly a cryo-pressure tank for a motor vehicle, having a storage volume for accommodating the stored gas, a mixing device is provided in the storage volume for mixing the gas stored in the storage volume.

First claim

What is claimed is:

1. A motor vehicle, comprising:
a storage vessel having outer and inner walls and insulation arranged therebetween and a storage volume within the inner wall accommodating cryogenic gas or cryogenic compressed gas;
a mixing device arranged in the storage volume, the mixing device having a movably disposed body in the storage volume for mixing gas stored in the storage volume; and
a fixed support arranged within the storage volume between a region adjacent to a first longitudinal end of the storage volume to a region adjacent to a second longitudinal end of the storage volume and parallel to a longitudinal axis of the storage volume,
wherein the movably disposed body is supported by the fixed support within the storage volume and the movably disposed body is linearly displaceable along the fixed support parallel to the longitudinal axis of the storage volume in response to motion of the storage vessel during operation of the motor vehicle.

2. The motor vehicle according to claim 1 , further comprising:
a displaceable bearing of the movably disposed body on which the linearly displaceable movably disposed body is supported by the fixed support in the storage volume, the displaceable bearing being oriented in a longitudinal direction of the motor vehicle.

3. The motor vehicle according to claim 1 , wherein the movably disposed body is swivelably arranged on the fixed support in the storage volume.

4. The motor vehicle according to claim 2 , wherein the movably disposed body is swivelably arranged on the fixed support in the storage volume.

5. The motor vehicle according to claim 1 , wherein the movably disposed body is arranged in a freely movable manner.

6. The motor vehicle according to claim 2 , wherein the movably disposed body is arranged in a freely movable manner.

7. The motor vehicle according to claim 1 , wherein the movably disposed body has a disc-shape.

8. The motor vehicle according to claim 2 , wherein the movably disposed body has a disc-shape.

9. The motor vehicle according to claim 1 , wherein the movably disposed body is in a pendulum form having a mass body linked to a pivot bearing via a rod.

10. The motor vehicle according to claim 1 , wherein the movably disposed body includes at least one through-opening.

11. The motor vehicle according to claim 7 , wherein the movably disposed body includes at least one through-opening.

12. The motor vehicle according to claim 9 , wherein the movably disposed body includes at least one through-opening.

13. A storage vessel for a motor vehicle, comprising:
a cryogenic storage tank having outer and inner walls and insulation arranged therebetween and accommodating cryogenic gas or cryogenic compressed gas in a storage volume thereof;
a mixing body arranged in the storage volume, the mixing body being movably disposed in the storage volume to mix gas stored therein;
a fixed support arranged within the storage volume between a region adjacent to a first longitudinal end of the storage volume to a region adjacent to a second longitudinal end of the storage volume and parallel to a longitudinal axis of the storage volume,
wherein the mixing body is supported by the fixed support within the storage volume and the movably disposed body is linearly displaceable along the fixed support parallel to the longitudinal axis of the storage volume in response to motion of the storage vessel.

14. The storage vessel according to claim 13 , wherein the mixing body includes a displaceable bearing on which the linearly displaceable movably disposed body is supported by the fixed support in the storage vessel, the displaceable bearing being oriented in a longitudinal direction of the motor vehicle.

15. The storage vessel according to claim 13 , wherein the mixing body is disposed in a swivelable manner in the storage volume.

16. The storage vessel according to claim 14 , wherein the movable body is in a disc-shape.

17. The storage vessel according to claim 14 , wherein the movable body is configured as a pendulum displaceable in the longitudinal direction and swivelable on the fixed support about a longitudinal axis.

18. The storage vessel according to claim 16 , wherein the mixing body comprises at least one through-opening configured to facilitate mixing of the gas upon displacement of the mixing body.
