Abstract

A pressure accumulator with a connecting device, in which the pressure accumulator and the connecting device are connected together fluid-conductively. The pressure accumulator at a first axial connecting segment has a transverse bore which intersects an axial bore of the pressure accumulator, in which the transverse bore is configured for fluid-conductive connection with the connecting device.

First claim

What is claimed is:

1. A pressure accumulator assembly for a motor vehicle, the pressure accumulator assembly comprising:
at least two pressure accumulators having a first connecting segment at a first end, and a second connecting segment at a second end opposite to the first end, the first connecting segment and the second connecting segment each having an axial bore and a traverse bore which intersects the axial bore permitting fluid flow therethrough;
a connecting device mounted to the motor vehicle, the connecting device having a first connecting element having a first connecting element groove to receive a first clamp connecting element and thereby connect the first connecting element fluid-conductively to the at least two pressure accumulators at the traverse bore of the first connecting segment upon insertion of the at least two pressure accumulators into an opening at the first connecting element, and a second connecting element having a second connecting element groove to receive a second clamp connecting element and thereby connect the second connecting element fluid-conductively to the at least two pressure accumulators at the traverse bore of the second connecting segment upon insertion of the at least two pressure accumulators into an opening at the first connecting element;
sealing rings arranged on the at least two pressure accumulators at both sides of the traverse bore to establish a seal between the at least two pressure accumulators and the connecting device; and
at least one centering element arranged between the connecting device and the at least two pressure accumulators upon insertion of the at least two pressure accumulators into the first connecting element and the second connecting element to maintain a radial orientation of the at least two pressure accumulators relative to the connecting device.

2. The pressure accumulator assembly of claim 1 , wherein the first clamp connecting element and the second clamp connecting element respectively comprises a spring element.

3. The pressure accumulator assembly of claim 2 , wherein the first connecting element groove and the second connecting element groove respectively includes an axial movement space to receive the spring element.

4. The pressure accumulator assembly of claim 1 , further comprising a cover to cover the opening and indicate a state of sealing of the at least two pressure accumulators.

5. The pressure accumulator assembly of claim 1 , further comprising a valve arranged in the axial bore.

6. The pressure accumulator assembly of claim 1 , further comprising a nominal break point in the first connecting segment and the second connecting segment.

7. The pressure accumulator assembly of claim 6 , further comprising a flow limiter arranged in the at least one pressure accumulator so as to remain in the at least two pressure accumulators upon breakage at the nominal break point.

8. The pressure accumulator assembly of claim 1 , further comprising fixing points on the first and second connecting elements to mount the connecting device to the motor vehicle.

9. The pressure accumulator assembly of claim 1 , further comprising a filling valve unit and/or an extraction valve unit arranged in or on the connecting device.

10. A pressure accumulator assembly for a motor vehicle, the pressure accumulator assembly comprising:
a connecting device including a first connecting element having first fixing ends to mount the connecting device to the motor vehicle, a first connecting element groove to receive a first clamp connecting element, and a first transverse bore to permit a fluid flow therethrough, and a second connecting element having a second fixing ends to mount the connecting device to the motor vehicle, a second connecting element groove to receive a second clamp connecting element, and a second traverse bore to permit fluid flow therethrough;
at least two pressure accumulators having a first connecting segment at a first end, and a second connecting segment at a second end opposite to the first end, the first connecting segment having a third transverse bore in a fluid-conductive connection with the second transverse bore of the first connecting element upon insertion of the at least two pressure accumulators into an opening at the first connecting element and clamping of the at least two pressure accumulators by the first clamp connecting element, and the second connecting segment having a fourth transverse bore in a fluid-conductive connection with the second transverse bore of the second connecting element upon insertion of the at least two pressure accumulators into an opening at the second connecting element and clamping of the at least two pressure accumulators by the second clamp connecting element; and
at least one centering element arranged between the connecting device and the at least two pressure accumulators to maintain a radial orientation of the at least two pressure accumulators relative to the connecting device.

11. The pressure accumulator assembly of claim 10 , wherein the first clamp connecting element and the second clamp connecting element respectively comprises a spring element.

12. The pressure accumulator assembly of claim 11 , wherein the first connecting element groove and the second connecting element groove respectively includes an axial movement space to receive the spring element.

13. The pressure accumulator assembly of claim 10 , further comprising a cover to cover the opening and indicate a state of sealing of the at least two pressure accumulators.

14. The pressure accumulator system of claim 10 , further comprising sealing rings on both sides of the traverse bore to establish a seal between the at least two pressure accumulators and the connecting device.

15. The pressure accumulator assembly of claim 10 , further comprising a valve arranged in the axial bore.

16. The pressure accumulator assembly of claim 10 , further comprising:
a nominal break point in the first connecting segment and the second connecting segment; and
a flow limiter arranged in the at least one pressure accumulator so as to remain in the at least two pressure accumulators upon breakage at the nominal break point.

17. A pressure accumulator assembly for a motor vehicle, the pressure accumulator assembly comprising:
a connecting device including a first connecting element having the first fixing ends to mount the connecting device to the motor vehicle, a first connecting element groove to receive a first clamp connecting element, and a first traverse bore to permit a fluid flow therethrough, and a second connecting element having second fixing ends to mount the connecting device to the motor vehicle, a first connecting element groove to receive a first clamp connecting element, and a second transverse bore to permit fluid flow therethrough; and
a plurality of pressure accumulators with a push-fit or clamp connection to the connecting device, and having a first connecting segment at a first end thereof, and a second connecting segment at a second end opposite to the first end, the first connecting segment having a third transverse bore in a fluid-conductive connection with the second transverse bore of the first connecting element upon insertion of the pressure accumulators into an opening at the first connecting element and clamping of the pressure accumulators by the first clamp connecting element, and the second connecting segment having a fourth transverse bore in a fluid-conductive connection with the second transverse bore of the second connecting element upon insertion of the pressure accumulator
