The paper presents a mathematical model of a test hydraulic system with an axial piston pump with an inclined disc and a pressure regulator. The authors propose the analysis of a mathematical model using a block diagram in an automated calculation program SimInTech. Transient processes in the hydraulic system have been obtained during abrupt closing and opening of the throttle simulating the load. The calculation showed that the pressure regulator has a speed sufficient for the system and qualitatively performs the main functions, coping with maintaining the pressure in the design range with a sharp change in the load from the consumer. Technological limits of the piston stroke that were added to the design allow to limit the range of the piston stroke and increase the speed of the system.
