Abstract
A conveying device for metering of bulk material includes a sleeve having an interior region having an inner threaded groove. The threaded groove is disrupted by a plurality of cross-wise extending compensating grooves. The conveying device further includes a rotatable part, at least a portion of the rotatable part being disposed inside of the interior region of the sleeve. The rotatable part has one or more flexible first bodies, an outermost point of the first bodies extending to an inner wall of the sleeve. The device conveys bulk material as the rotatable part rotates such that the first bodies move along the threaded groove from one compensating groove to a next compensating groove.
