Patent ID: 8770542

Claim:
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.
