Abstract
1289473 Rotary positive-displacement machines TEGALEMIT (ENG.) Ltd 23 Sept 1969 [23 Sept 1968] 45026/68 Heading F1F To improve sealing in a pump, or motor, of the diametral-sliding-vane type the rotor 4 and the outer edges of the vanes 7, 8 are coated with an elastomer, axial grooves 16. . 19 and 24 being provided in the rotor coating to minimize friction. Alternatively, the peripheral wall of a chamber 3 for the rotor is coated with an elastomer Fig. 6 (not shown), the coatings on the circumferential surface of the rotor and on the vanes being dispensed with but the grooves 24 being retained. Ports (not shown) at the inner ends of inlet and outlet ducts 1, 2 are formed in the end walls of the chamber 3. The vane 8 may comprise two mutually-overlapping parts, Figs.2 and 4 (not shown). The profile of the peripheral wall of the chamber 3 is described in detail, Figs. 3α and 3b (not shown), and is constituted by a series of circular arcs.
