Abstract

A regenerative heat exchanger having a first part which is essentially cylindrical and which contains a regenerator mass, and a second part which comprises axially directed inlet ducts and outlet ducts for heat emitting and heat absorbing media. The inlet and outlet ducts are separated from each other by sector shaped plates positioned for sealing purposes close to end surfaces of the first part, and the sector shaped plates are pivotally connected to axially fixed center plates positioned at ends of the first part and attached to the second part. At least one cylindrical stop bar is provided at a radial outer end of each of the sector shaped plates for setting a clearance between the radial outer ends of the sector shaped plates and respective edge flanges provided at each end of the first part. The stop bars are mounted perpendicular to the sector shaped plates and are journalled in an axially displaceable manner in respective cylindrical sockets provided at the radial outer ends of the sector shaped plates. The stop bars are adjustable by a screw mechanism connected to the respective ends of the sector shaped plates. In addition, at least one axial through passage, formed between a peripheral surface of each of the stop bars and an inside surface of the respective cylindrical sockets, is provided through which a first pressurized fluid may be applied. One of the first part and the second part is rotatable relative to the other around a common center axis.
