Power regulators are attached devices of hydraulic pumps with variable
capacity. Theses have the means to modify the pump capacity depending of
the pressure from the circuit served by the pump. In this way, it result that
the pump hydrostatic power will be mantained at the nominal working
point value from external characteristics of driving unit motor. Thus, the
product beetween pump momentary flow and the momentary pressure from
pump circuit, give the same value all the time, the mathematical law for
this phenomenon beeing a equilater hyperbola. In this paper the authors
present the mathematical model for the control system ensemble, composed
from pump balance system, dog watch system and power regulator unit.
