Abstract: A rotary, regenerative heat exchanger includes an inner cylindrical hub (2) provided in a vertical position, a rotor (1) containing a heat exchange medium, first attachment members (30) for attaching the rotor to the hub, and a stationary casing (6) surrounding the rotor. A bearing (3) is provided to journal a lower end of the hub, and a slow moving hydraulic motor (4) is adapted to slowly turn the hub. The motor is provided with a housing enclosing a built-in radial bearing (26) and coaxially therewith a cylinder block and cam surface arrangement having a circular cylinder block (24) and a cam surface (21) surrounding the cylinder block and cooperating with a piston mechanism (22, 23) of the cylinder block such that reciprocation of the piston mechanism causes relative motion between the cylinder block and the cam surface. Second attachment members (5, 8, and 10) are provided to attach the motor to the stationary casing and to the hub, respectively.

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.

Abstract: A regenerative heat exchanger includes first and second parts. The first part is essentially cylindrical, includes a regenerative mass, and is rotatable in relation to the second part around a common center axis. The second part includes axially directed inlets and outlets for heat emitting and heat absorbing media. The inlets and outlets of the second part are mutually separated by sector shaped plates for sealing purposes positioned near to end surfaces of the first part. The sector shaped plates are pivotally connected to axially fixed center plates attached to the second part at ends of the first part, and each of the sector shaped plates includes at a radially outer end thereof a device which has at least one support member including a circular cylindrical sliding shoe for setting a clearance between respective ends of the sector shaped plates and an edge flange provided at each end of the first part.
