PCT No. PCT/SE97/00320 Sec. 371 Date Aug. 26, 1998 Sec. 102(e) Date Aug. 26, 1998 PCT Filed Feb. 25, 1997 PCT Pub. No. WO97/31209 PCT Pub. Date Aug. 28, 1997A valve device comprises a valve having an outlet passage (6, 7), a stationary surface, and a rotatable support member (15, 16) at a distance from the stationary surface, and a membrane (19) provided between the stationary surface and the support member. The membrane (19) is attached to 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 the stationary surface the membrane covers an orifice (6, 7) associated with the outlet passage and located at the stationary surface and when the support member is in a second rotating position said opening is uncovered. The support member (15, 16) is provided rotatably about an axis (12) which in a plane, in which the axis (12) extend, forms an angle together with the generatrix of the stationary surface (10, 11).
