Abstract

Abstract 117,110. Jones, T. B. Dec. 21, 1917. Flexible-tube type.-In pumps of the kind comprising a collapsible elastic tube adapted to be pressed at successive points against an abutment by a continuous series of movable external members travelling lengthwise of the tube, the pressing members consist of a series of antifriction rollers 15 carried at equal angular distances apart between a pair of rotating disks 12, the collapsible tube 21 is coupled to the delivery pipe 23 by a device, which allows the end of the tube to rise and fall, and the abutment 16 consists of a plate moved about the axis 11 of the disks and formed at its end with apertured bosses 17 which slide on studs 18 and are pressed towards the axis 11 by springs 19. The disks 12 may be driven by an aeromotor 37 through worm-gearing 33, 32. The whole apparatus is enclosed in a two-part casing 38, 39, and may be used on aircraft for pumping petrol.
