comprising a tube of flexible material in which a section of a fluid channel is formed, a valve component assigned to the tube, a squeeze element, which is formed and configured on the valve component by pressing against an outside surface of the tube to control a flow of a fluid through the fluid channel, optionally up to the closing of the fluid channel, a guide section, which is formed on the valve component, and a guide assigned to the valve component, which cooperates with the guide section in a relative movement of the guide and valve components relative to one another in the longitudinal direction of the tube, such that the squeeze element is displaced in the relative movement, changing the pressure on the outside surface of the tube and thus changing the flow through the fluid channel. ## Claims ### Claim 1 A valve for controlling a flow of a fluid through a fluid channel, comprising: a tube of flexible material in which a section of the fluid channel is formed, a valve component assigned to the tube, a squeeze element which is formed and configured on the valve component by pressing against an outside surface of the tube to control a flow of a fluid through the fluid channel, optionally up to the closing of the fluid channel, a guide section, which is formed on the valve component and a guide assigned to the valve component, which cooperates with the guide section in a relative movement of the guide and the valve component relative to one another in the longitudinal direction of the tube, such that the squeeze element is displaced in the relative movement, changing the pressure on the outside surface of the tube and thus changing the flow through the fluid channel, and wherein the squeeze element and the valve component are structured and arranged for high frequency displacement with a frequency between 10 Hz and 500 Hz so as to move the squeeze element to open and at least partially close the fluid channel in the tube. ### Claim 2 (depends on 1) The valve according to claim 1, wherein the valve component is formed with a reversibly displaceable cantilevered arm on which the squeeze element is arranged. ### Claim 3 (depends on 2) The valve according to claim 2, wherein the cantilevered arm extends along the tube and optionally forms an acute angle with the longitudinal direction of the tube. ### Claim 4 (depends on 1) The valve according to claim 1, wherein the guide section is formed on the squeeze element. ### Claim 5 (depends on 1) The valve according to claim 1, wherein the guide is formed on a wall section. ### Claim 6 (depends on 1) The valve according to claim 1, wherein the valve component is formed as a microvalve component. ### Claim 7 (depends on 1) The valve according to claim 1, wherein the squeeze element is formed, extending around at least half of the tube. ### Claim 8 (depends on 1) The valve according to claim 1, wherein the squeeze element is formed with a plurality of partial squeeze elements, which are arranged around the tube. ### Claim 9 (depends on 1) The valve according to claim 1, wherein the at least one part of the plurality of partial squeeze elements is arranged so they are supporting one another in at least one end position. ### Claim 10 (depends on 1) The valve according to claim 1, wherein the valve component is designed at least in part as an injection-molded part. ### Claim 11 (depends on 1) The valve according to claim 1, wherein the valve component is arranged on the tube. ### Claim 12 (depends on 1) The valve according to claim 1, wherein the fluid channel runs through a compensating section, which at least partially compensates for the relative movement of the guide and the valve component. ### Claim 13 A system having at least one valve for controlling a flow of a fluid through a fluid channel, comprising: a tube of flexible material in which a section of the fluid channel is formed, a valve component assigned to the tube, a squeeze element, which is formed and configured on the valve component by pressing against an outside surface of the tube to control a flow of a fluid through the fluid channel, optionally up to the closing of the fluid channel, a guide section, which is formed on the valve component, a guide assigned to the valve component, which cooperates with the guide section in a relative movement of the guide and the valve component relative to one another in the longitudinal direction of the tube, such that the squeeze element is displaced in the relative movement, changing the pressure on the outside surface of the tube and thus changing the flow through the fluid channel, and a pressure-applying device which is in fluid connection with the fluid channel and is configured to apply a pressure to the fluid in the fluid channel, and wherein the squeeze element and the valve component are structured and arranged for high frequency displacement with a frequency between 10 Hz and 500 Hz so as to move the squeeze element to open and at least partially close the fluid channel in the tube. ### Claim 14 A multiple-way valve having a plurality of valves for controlling a flow of a fluid through a fluid channel, comprising: a tube of flexible material in which a section of a fluid channel is formed, a valve component assigned to the tube, a squeeze element, which is formed and configured on the valve component by pressing against an outside surface of the tube to control a flow of a fluid through the fluid channel, optionally up to the closing of the fluid channel, a guide section, which is formed on the valve component, a guide assigned to the valve component, which cooperates with the guide section in a relative movement of the guide and the valve component relative to one another in the longitudinal direction of the tube, such that the squeeze element is displaced in the relative movement, changing the pressure on the outside surface of the tube and thus changing the flow through the fluid channel, and wherein the squeeze element and the valve component are structured and arranged for high frequency displacement with a frequency between 10 Hz and 500 Hz so as to move the squeeze element to open and at least partially close the fluid channel in the tube.
