Abstract

1,114, 680. Rotary flexible-tube pumps. SIBANY MANUFACTURING CORPORATION. May 17, 1965 [May 18, 1964], No.1434/68. Divided out of 1, 114, 679. Heading F1F. Apparatus for pumping a fluid comprises a flexible conduit formed of two flexible walls sealed together at their longitudinal edges, the conduit being arranged in the form of a ring, a rigid cylindrical supporting wall arranged in contact with one wall of the conduit, a protective supporting cover in contact with the other wall and means in pressure contact with the cover for collapsing the conduit when the conduit and pressure contact areas are moved relative to one another. As shown, the flexible conduit encircles and rotates with a shaft 2 and comprises walls 68, 70 and an outer flexible protective cover 72. Fluid inlet and outlet passages 62, 64 formed in the shaft communicate with the interior of the conduit and fixed rollers 80 act on the outside of the conduit to force the fluid therethrough. The rollers have axles 82 disposed in slots 94 in a cam-plate 92 so that rotation of the latter varies the radial positions of the rollers and hence varies the degree of compression of the fluid in the conduit. Shaft 2 forms part of a rotary heat pump and a gaseous refrigerant is compressed in the flexible conduit. The flexible cover 72 may be formed of a plurality of springs, Figs. 10-12 (not shown) and the flexible conduit may be stationary, in which case the rollers are mounted on the rotating shaft and act on the inner wall of the conduit, Fig. 8 (not shown). In further modification, the flexible conduit is collapsed by an eccentrically mounted ring acting on either the outer wall of the conduit, Fig.13 (not shown) or on the inner wall, Fig.14 (not shown). In the former case the conduit rotates and in the latter it is fixed. The eccentricity of the ring is maintained by adjustable rollers in both embodiments, but in the embodiment of Fig.14 the rollers may be replaced by a shaft having a projection engaging the inner surface of the ring.
