Abstract:
1. A valve for opening and closing the flow in a fluid line, comprising: a flexible sleeve inserted in a space between two free line ends of the fluid line, two transverse folds made at mutual distance on the sleeve and directly or indirectly connected to each line end of the two line ends, a sleeve section connecting the two folds, a closing section made on the sleeve section and which includes at least a main part of the sleeve section and is made as two strips passing into each other in opposite transitions, two opposite slides each engaging their respective side of the closing section, and means for displacing the slides between a position in which they cause the closing section to close, and a second position in which the closing section is kept open, wherein the transitions are spaced by a distance that is larger than the diameter of the fluid line in the open state of the valve, the space between the two folds is formed as a circumferential groove defining a depth and a width, and the slides are formed as plates which at least, when the valve is closed, completely are filling the depth of the groove and at least partly the width of the groove.
