Abstract

The device has a structural body (6) defining a cavity (7) with respect to a fluid circulation path (8) and not directly exposed to fluid flow (F). A rotating repression unit (2) is displaced and positioned in translation in axial direction of shaft structures (4, 4`). The displacement and positioning of the unit (2) is controlled by a control actuator (9). The actuator is mounted on or in a rotating unit/shaft structure assembly. An independent claim is also included for a cooling liquid circulation circuit of an internal combustion engine comprising a variable flow pump device.
