ABSTRACT:
An apparatus for feeding bulk material includes a rotor with a plurality of radially extending vanes which are supported on a hollow shaft and are provided with sealing strips at their end faces. Shiftable within the shaft is an adjusting bar with at least two axially spaced conical surfaces which cooperate with push rods having one end bearing against the conical surfaces and another end in force-locking connection with the sealing strips. The adjusting bar is acted upon by a force-applying unit which subjects the adjusting bar to a constant axial holding force which is independent of the axial displacement of the adjusting bar so that a sufficient contact pressure is continuously maintained by which the sealing strips are urged against the housing.
