Abstract

850,738. Thermal regenerators. SVENSKA ROTOR MASKINER A.B. Feb. 21, 1957 (Feb. 27, 1956], No. 5869/57. Classes 64(1) and 64(2) In a rotary matrix type thermal regener-- ator, the normal sealing gap provided between each of the two stationary end sealing plates and the rotor is automatically maintained by means of a thermally sensitive compensating device which interconnects the end plates. The sealing gap between the rotor and a circumferential sealing plate may be similarly maintained. The minimum sealing gap applicable under continuous operating conditions is set by manual adjustment and the arrangement is such that thereafter, owing to the compensating device, substantially no movement of the seals takes place due to temperature changes. Hence when the apparatus is shut down and the rotor contracts on cooling, theactual sealing gap tends to increase so that on restarting a sufficient gap always exists to allow for the normally rapid expansion of the rotor. Fig. 5 shows one form in which the compensating device interconnecting the opposed sealing end plates 18, 19 comprises telescoped members- 20, 21, 22 interconnected at their ends in the manner shown, the expanding member 21 being made of a material such as aluminium having a relatively high coefficient of thermal expansion and the other members 20, 22 being made of material having a relatively low coefficient of thermal expansion, e.g. "Invar" (Registered Trade Mark) steel. The upper sealing plate 18 is resiliently mounted and the initial manual adjustment of the sealing gap is made by means of nut 25. A further form is described (Fig. 6, not shown) utilizing two rods of different material, one of which is secured at one end to a circumferential sealing plate, itself directly attached to the lower end sealing plate. In Fig. 7, showing a circumferential seal, the thermally sensitive device comprises bimetallic washers of circular or rectangular shape which, placed under the adjusting nut, assume the cross-sectional form illustrated when hot and which distort on cooling so as to present a concave face to the stationary casing portion 52 thereby widening further the gap between circumferential sealing plate 53 and the surface of rotor 54. Arrangements are also described in which either the end or circumferential sealing plates serve as one of the members of the compensating device.
