- 11 - Abstract Feed Pump A pump comprising two discs mounted for rotation on a common central shaft, a plurality of rollers capable of free rotation positioned between the discs and mounted on shafts so that part of each roller extends beyond the circumference of the discs, a channel surrounding and spaced uniformly from an arc of the circumference of the discs, two parallel fixed plates one on the outer side of each disc, an elastic membrane connecting the peripheries of the fixed plates and extending around the peripheries for a distance at least as great as the distance between the shafts of two adjacent rollers, whereby each roller has a profile adapted to mate with the channel and an adjacent pair of rollers is adapted to stretch the elastic membrane into contact with the inside wall of the channel to form an occlusion in the channel, and drive means for rotating the discs to form the occlusions.
