1,046,106. Thermal regenerators. SVENSKA ROTOR MASKINER A.B. May 28, 1963 [May 28, 1962], No. 21205/63. Heading F4K A thermal regenerator comprises a cylindrical shell 32 joined by radial partitions 28 to a rotor post (Fig. 4, not shown, Fig. 2) comprising a central support shaft 10, a concentric post shell 24, and a plurality of supporting ribs 26 extending tangentially from the support shaft to the post shell, which are adapted to flex laterally to compensate for expansion of the post shell 24, the whole being placed within a housing 52 having inlet ports 54, 58 and outlet ports 56, 62 for a heating fluid and a fluid to be heated, respectively. In the form shown, the post shell 24 and fixed partitions 28 extend axially a distance less than the length of the rotor shell, being positioned at the upper, cold end of the rotor. Dependant from the fixed paritions 28, to which they are pivotally linked at 35, are partitions 33, the ends of which loosely abut the inner surface of the rotor shell and the outer surface of a cylindrical jacket 36 which is a continuation of the post shell 24, channel members 42 providing slots for the edges thereof (Fig. 3, not shown). Sealing between adjacent compartments is effected by the channel members 42, inter-partition seals 44 and radial seals 46. Circumferential seals 48 are positioned around the end edges of the rotor. The inner surfaces of the post shell 24 and the cylindrical jacket 36 are covered with a layer of thermal insulating material 68, cooling air flowing between the said insulating material 68 and the rotor post 10, by natural circulation. The rotor post 10 and the housing 52 are suspended from an independent support beam by support means 12, 64 respectively, and are attached at their bases to a secondary beam 18 which is suspended by rods 22 from the support beam 14.
