The aim of this paper is a detailed analysis of a particular mechanism with variable piston stroke. This crank mechanism is presently applied to metering pumps, because it allows the piston stroke to be adjusted in length and permits the pump flow to be changed also during the pump functioning. The following analysis shows the different characteristics of piston motions obtainable by changing the ratios among the mechanism rod lengths.
