The article examines the main dynamic characteristics of the pressure regulator of the axial piston pump. Mathematical simulation of the pump pressure regulator in the software package MATLAB Simulink is carried out. According to the results of mathematical modeling, such basic dynamic characteristics as discharge pressure, pump feed, slide valve travel and servo piston movement, without taking into account the effect of dry friction forces and with the effect of dry friction forces are obtained. Influence of dry friction forces on the main dynamic characteristics of the pressure regulator is considered. Recommendations for reducing the effect of dry friction forces on the basis of the results obtained are given.
