Abstract

769,378. Rotary pumps. LE GRAZIE, G. May 6, 1955 [May 17, 1954], No. 13200/55. Class 110 (2). A pump, Fig. 1, of the flexible vane type comprises a rubber rotor 14 mounted in a liner 18, which in turn is adjustably mounted in the pump casing 16 and is manually operable to vary the capacity of the pump and effect reversal of the flow therethrough without reversing the direction of rotation of the rotor. In a modification, Fig. 4 (not shown), the liner is eccentrically bored relative to the casing. The pump of Fig. 1 may be provided with liner holes for idling purposes or two sets of inlet and outlet ports (see Figs. 9 and 10, not shown), respectively. Again, the inlet and outlet ports of the casing of Fig. 1 may be diametrically offset and the liner need only consist of a plate having a projection (see Figs. 12 and 13, not shown), respectively.
