Static and dynamic characteristics of a class of pressure compensated flow control valves

The study of the perfomdnce of hydraulic control valveshas gra.wn rapidely, due to the wide range of applications inmost of the modern machines and equipment.The object ofthis work is to study the static and dynamic characteristicsof the pressure compensated flow control v.:llves, which haveseries pressure compensators, when they are arranged in ameter-out mode of speed control in hydraulic c i rcu it:s .The simulation of the chdracteristics is c.:lrried outusing a. digital computer, on the basis ofdevelopedcone i der a t ion the effects of the basic valve tion l iriear it ies .The Qccuracy of the derived models is ascertained bycomparing the characteristics obtained through simulationwith the characteristics obtdined experimentally for acertain valve. The effect of some constructional parameters
