ABSTRACT:
A positive displacement pump includes a flexible endless belt 4 disposed around spaced, parallel drive rollers 8, 9 within a housing 2. The belt is non-extensible in the peripheral direction and carries elastically deformable teeth on its outer surface. The spaces between the teeth form conveying chambers 4b whose volumes vary in an expansion-contraction sense as the belt runs around a roller between inlet and outlet openings 11, 13 in the housing.
