【 摘 要 】

This paper surveys mechanism of supply regulation for axial-piston pump with adjustable-angle swash plate operating with constant power. The mechanism includes a piston, whose working space is connected to delivery port, regulation unit and two springs. Least square method and successive approximations method are used to calculate parameters of the mechanism: cut-in pressure level for the second spring and springs stiffness. Regulation effectiveness is estimated by calculation of relative error of power delivered.
