Abstract:
A valve device comprising a valve having:an outlet passage;a stationary surface presenting a generatrix and configured as at least a part of a circular, annular path having its center of rotation at an axis;a support member provided at a distance from the stationary surface and rotatable about said axis; anda membrane of flexible material provided between the stationary surface and the support member in such a manner that when the rotatable support member is in a first rotating position in relation to a stationary surface, the membrane covers an orifice associated with the outlet passage and is located at the stationary surface, and when the support member is in a second rotating position said orifice is uncovered, wherein the generatrix of the stationary surface forms an angle together with the axis in a plane in which both the generatrix and the axis extend, and wherein the flexible material is bent in a loop between the stationary surface and the support member in such a manner that a part of the loop covers the orifice in the first rotating position and that the loop uncovers the orifice in the second rotating position.
