Abstract
The results presented and discussed in the paper, are obtained by carrying out testbed and modelling (computational) experiments. The objects of the experiments are axial-piston hydraulic machines “Rexroth” - pump, type A4V.40 and hydraulic motor, type A2FM.56.The influence of the commutative processes on the operation of the hydraulic machines is analyzed. The so called "Dynamic variation" under steady-state operating modes and the factors with impact upon it are estimated.
