ensure a shock-free closure of the constituting links of the mehanzim to ensure reliable operation of the gas
distribution mechanism.
The features of the existing cam mechanisms and techniques for their design were considered. The
problems of typical cam mechanisms associated with exceeding the value of the boundary acceleration leading to
the rupture of the power links of the mechanism are described. A new method for designing cam mechanisms
based on the expansion of the function in a series based on the "Decoder" method is proposed. Mathematical
dependencies describing the basic laws of the pusher motion (displacement, velocity and acceleration) are
obtained with their subsequent implementation by computational methods on a personal computer.
The proposed dependencies for the law of motion of the pusher showed a decrease in the level of the
boundary acceleration of the pusher motion, with the maximum value of the valve cross section due to the
conservation of the rectangular form of the acceleration law.
