ROTATING MULTIPORT VALVE

A multiport valve module system for fluids, comprising an at least four-way valve housing (1), having a central axis X, which encloses a working chamber (1.1) having an inner housing surface (1.6) and having at least four ports (1.3a-1.3d) for supplying and/or discharging a medium (M1, M2) into or out of the working chamber (1.1). The valve housing (1) includes a cover (1.2) that is assembled to the valve housing (1) for sealing the working chamber (1.1). The system has a valve body (2) which is placed in the working chamber (1.1) and being rotatable about the central axis X and being translatable in direction of the central axis X and having an outer valve surface (2.2). The valve body (2) has at least two separate channels (2a, 2b) with plurality of openings (2.7) on the outer valve surface (2.2) for connecting two ports. The system has a separate drive shaft (3.1) for connecting a drive with the valve body (2) with the drive shaft (3.1) guided through the cover (1.2). The rotatable multiport valve module system is said to be fast and easy to switch at the same time. For that a torque on the drive shaft (3.1) is permanently transferred to the valve body (2) such that the valve body (2) rotates synchronously with the drive shaft (3.1) when the drive shaft (3.1) is driven by a drive and cams (1.4a, 2.1 a) are provided at the valve body (2) and at the valve housing (1), which cause a translational movement of the valve body (2) in axial direction. L'invention concerne un système de module de vanne multivoies pour fluides, comprenant un boîtier (1) de vanne à au moins quatre voies, présentant un axe central X, qui renferme une chambre de travail (1.1) comportant une surface de boîtier interne (1.6) et au moins quatre orifices (1.3a à 1.3d) pour l'introduction et/ou l'évacuation d'un milieu (M1, M2) dans ou hors de la chambre de travail (1.1). Le boîtier de vanne (1) comprend un couvercle (1.2) qui est fixé sur le boîtier de vanne (1) pour fermer hermétiquement la chambre de travail (1.1). Le système comprend un corps de vanne (2) qui est placé dans la chambre de travail (1.1) et qui peut tourner autour de l'axe central X et peut être déplacé en translation dans la direction de l'axe central X et qui comporte une surface de vanne externe (2.2). Le corps de vanne (2) présente au moins deux passages séparés (2a, 2b) dotés d'une pluralité d'ouvertures (2.7) sur la surface de vanne externe (2.2) pour relier deux orifices. Le système comprend un arbre d'entraîneme
