Abstract: Two kinematic diagrams are presented, consisting of two combined toggle mechanisms and a piston pump. Kinematic calculations of the moving link parameters for both kinematic diagrams resulted in the determination of the displacement of the working and idle stroke lengths S of the piston as a function of the toggle mechanism swing angle φ and the change in the toggle length and crank radius of the piston pump. The numerical value of the coefficient K of the average toggle mechanism slider velocity, K = 2, and the displacement of the piston stroke S were obtained: for a toggle-piston pump, S = 1.25, and for a crank-toggle mechanism, S K = 0.7 m. Various asymmetric phase angles were calculated for the working φ p and idle φ x strokes of the slider during rotation of the toggle mechanism crank for both kinematic diagrams. The relationship between the center distance α and the position of the fixed support point O 1 of the crank axis of rotation to the support point O 2 of the rocker arm is obtained. The numerical values of the stroke displacement S D , linear velocity V D , and acceleration α D of the pump piston for both kinematic diagrams of the rocker-piston pump mechanism are presented in tabular form by numerical values and in kinematic diagrams.
