valve and fluid connection system, comprising a casing having a chamber with a first internal connection element and a first external connection element; comprising a first movable valve element in the chamber; and comprising an actuating element which has a fluid communication system with a second internal connection element and a second external connection element; wherein the first internal connection element cooperates with the second internal connection element and the valve element to establish or block a fluid connection between the first and second external connection elements. ## Claims ### Claim 1 A fluid valve and fluid connection system comprising a housing having a receiving chamber with a first internal connection element and with a first external connection element, a first movable valve element arranged in the receiving chamber, and an actuating element, which has a fluid communication system with a second internal connection element and with a second external connection element, wherein the first internal connection element cooperates with the second internal connection element and the valve element to open or to block a fluid connection between the first and the second external connection elements, wherein the actuating element comprises at least one arm, wherein the at least one arm has at least one radially inwardly oriented protrusion, and wherein the housing comprises at least two grooves formed in a housing wall that are complimentary to the at least one radially inwardly oriented protrusion, wherein the grooves are arranged spaced apart from one another in the axial direction of the housing, wherein the actuating element is configured to be movable relative to the housing between a first position and a second position, wherein in the first position the fluid connection between the first and the second external connection elements is blocked, wherein in the first position the at least one arm is arranged such that the at least one radially inwardly oriented protrusion engages with a first groove associated with the first position, wherein in the second position the fluid connection between the first and the second external connection elements is open, wherein in the second position the at least one arm is arranged such that the at least one radially inwardly oriented protrusion engages with a second groove associated with the second position. ### Claim 2 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, wherein the actuating element is configured to be movable relative to the housing between a first position and a second position, wherein in the first position the fluid connection between the first and the second external connection elements is blocked, wherein in the second position the fluid connection between the first and the second external connection elements is open. ### Claim 3 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, wherein the actuating element has means that cooperate with means of the housing in order to define the first and the second positions. ### Claim 4 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, further comprising a blocking element, wherein the blocking element is configured to be movable from a blocking position to a nonblocking position, wherein when the blocking element is in the blocking position, the blocking element prevents the actuating element from adopting the second position, wherein when the blocking element is in the nonblocking position, the blocking element allows the actuating element to adopt the second position. ### Claim 5 (depends on 4) The fluid valve and fluid connection system as claimed in claim 4, wherein the blocking element is an open ring element, which grasps around the housing and prevents the actuating element from adopting the second position by limiting the movement of the actuating element in such a way that the at least one protrusion cannot engage with the second groove associated with the second position. ### Claim 6 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, wherein the housing comprises a first fastener configured to fasten the fluid vale and fluid system to a first storage vessel. ### Claim 7 (depends on 6) The fluid valve and fluid connection system as claimed in claim 6, wherein the housing further comprises the first external connection element, which is configured to establish a fluid connection to the first storage vessel. ### Claim 8 (depends on 6) The fluid valve and fluid connection system as claimed in claim 6, wherein the first fastener is formed in the manner of detent arms. ### Claim 9 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, wherein the actuating element comprises a second fastener configured to fasten the actuating element to a second storage vessel. ### Claim 10 (depends on 9) The fluid valve and fluid connection system as claimed in claim 9, wherein the actuating element further comprises the second external connection element, which is configured to establish a fluid connection to the second storage vessel. ### Claim 11 (depends on 10) The fluid valve and fluid connection system as claimed in claim 10, wherein the second external connection element is formed with two channels. ### Claim 12 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, wherein the first or the second external connection element is formed in the manner of a hollow cannula. ### Claim 13 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, wherein the first internal connection element is a hollow-cylindrical connecting piece and the second internal connection element is a hollow-cylindrical connecting piece, which engage with one another when moved between the first position and the second position. ### Claim 14 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, wherein the second internal connection element is a hollow-cylindrical connecting piece which, when moved between the first position and the second position, acts on the valve element. ### Claim 15 (depends on 14) The fluid valve and fluid connection system as claimed in claim 14, wherein the valve element in the first position of the actuating element blocks the fluid connection between the first and the second external connection elements and the valve element in the second position of the actuating element allows the fluid connection between the first and the second external connection elements. ### Claim 16 (depends on 1) The fluid valve and fluid connection system as claimed in claim 1, wherein the valve element has an approximately cylindrical region with spring arms protruding away from the cylindrical region. ### Claim 17 (depends on 16) The fluid valve and fluid connection system as claimed in claim 16, wherein the valve element is arranged with its approximately cylindrical region in the first internal connection element such that the approximately cylindrical region seals the first internal connection element against the second internal connection element, wherein the spring arms are each supported on an inner wall of the housing.
