The invention refers to a fan system () comprising a fan shroud () and a ring fan () having a hub (), a plurality of fan blades (), and a ring structure (). The ring structure () has a ring member () and a flange member (), the ring member () having a hollow cylindrical shape, the flange member () extending radially outwardly from the ring member (). The fan shroud () has an annular shroud flange (), a shroud body () and a plurality of shroud guide vanes (), the shroud flange () extending radially outwardly from the shroud body () and being disposed along the rotary axis (A) between the flange member () and the shroud body (), the shroud body () being disposed about the ring member () and having a first body portion (), a second body portion () and a divergent nozzle (). A recirculation throttle () is formed by the shroud body () and the ring member () at a location where the first and second body portions () of the shroud body () intersect one another. The divergent nozzle () and a trailing end () of the ring member () cooperate to form a dynamic sealing feature ().

Fan system with integrated fan-shroud channel for reduced recirculation flow

A fluid clutch device having a fluid clutch in a body and a cover. A fan member is attached to the device. The body and fan member are both centered on the cover.

Fluid clutch device

The present invention relates to a fluid accumulator chamber () of a fluid clutch device having an inner boundary wall () which runs around a central axis of rotation (M), having an outer boundary wall () which runs around axis of rotation (M), and having at least one filling opening () arranged in the outer boundary wall (), wherein the outer boundary wall () has, at the location of the filling opening (), a maximum spacing (R) to the central axis (M), which spacing decreases continuously to a point (P) of minimum spacing (R) to the central axis (M).
