This paper presents some theoretical considerations regarding the calculus of the transmission coefficient of the pressure energy in hydrostatic mechanisms. After defining all categories of transmission and efficiency coefficients, we present the laws of calculus for various combinations of hydraulic components and formulae of their resultant transmission coefficients. Beginning with the mathematical model of hydrostatic machines, presented in a generalized original form, we obtain the calculus formulae for overall transmission coefficients of a simple hydraulic circuit. These formulae can be useful in scientific researches, designing the equipment for the hydraulic drives and also in the didactic activity with students.
