A positive-displacement pump is shown in figure below. The pump consists of cam 1, piston 2, spring 3, cylinder 4, pipes 5, check valves 6 and 7, and reservoir 8. when the pump discharge pressure increases, the pump leakage increases between the piston and the cylinder. So the pump volumetric displacement increases decreases does not change when the piston diameter increases, the pump volumetric displacement. increases decreases does not change when the cam rotational speed increases, the pump volumetric displacement. increases decreases does not change
