## Abstract

Block storage element and method for supplying liquid to a block storage element. The block storage clement has an overflow and the method includes introducing the liquid into an overflow distributor with a distributor limit. The liquid is throttled by at least one passageway arranged in the distributor limit and gets into a tub area of the block storage element, and the liquid that is not drained by way of the at least one passageway is discharged via the overflow.

## Claims

### Claim 1

A method for supplying liquid to block storage elements including a first block storage element and second block storage element arranged one above the other, the method comprising:
introducing the liquid through a first liquid guide of the first block storage element into an overflow distributor in the first block storage element with a distributor limit and an overflow,
wherein a discharge end of the first liquid guide is arranged below an upper end of the overflow,
wherein the liquid is throttled by at least one passageway arranged in the distributor limit and gets into a tub area of the first block storage element,
wherein the liquid that is not drained by way of the at least one passageway is discharged from the first block storage element via the overflow and conducted in a liquid guide of the second block storage element arranged below the first block storage element.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the overflow is a first overflow and the liquid introduced into the block storage element from the overflow distributor is drained by way of a second inlet of a second overflow of an overflow collector.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the overflows of the first and second block storage elements are first overflows and the liquid introduced into the first and second block storage elements from respective overflow distributors is drained by way of a second inlet of a second overflow of an overflow collector in each of the first and second block storage elements.

### Claim 4 (depends on 3)

The method according to claim 3, wherein the liquid drained via the second overflow of the first block storage element is conducted into a second liquid guide of the second block storage element.

### Claim 5 (depends on 4)

The method according to claim 4, wherein the liquid conducted into the second liquid guide of the second block storage element via the second overflow of the first block storage element is transferred by way of a first inlet of the second overflow of the second block storage element into a third block storage element arranged below the second block storage element in the direction of gravity.
