A sleeve valve comprising a torpedo shaped core provided with radial, longitudinal ribs, a generally cylindrical sleeve surrounding the core and being made from radially elastically deformable material and a generally cylindrical housing, against which the sleeve is sealed at both ends and in which the core is supported by means of radial supports between each end of the sleeve and the corresponding end of the core at least two approximately radial fins being provided each located between two longitudinal ribs of the core, the contour of said fins facing the sleeve substantially corresponding to the shape the sleeve has at that point in its normally closed state. |
