Rotary valve for regulating flow, especially of liquids, e.g. in motor vehicle cooling systems comprises cross-section-adjusting elements that are each connected to a common drive shaft via a rotating gear

摘要

Rotary valve (1) comprises several cross-section-adjusting elements (2-6) that are each connected to a common drive shaft via a rotating gear (22-26). Preferred Features: The rotating gears have the same and/or different transmissions. At least one rotating gear has a decoupled region (35) over a partial angle of rotation (alpha , beta ). The decoupled region involves at least one gear wheel of the rotating gear that is tooth-free over at least one peripheral section (28).
