LOAD SENSING CIRCUIT AND ELECTROHYDRAULIC CONTROL FOR LOAD COMPENSATED DIRECTIONAL CONTROL VALVE.

摘要

load sensing circuit of a directional control valve (10) is sensitive to the load bearing devices for the detection of load pressure signals.identification of load pressure signals as positive or negative signals and transmission of signals in the control of compensator to constriction (12) of the directional control valve responsive to the load (10).the load pressure signals (d1, d2) are, at the same time signals (b1, b2) in the direction of travel of the load (w) is controlled electronically transmitted to a logical circuit (16) which identifies the charge pressure is positive or negative is the electrical signal corresponding to the command (f1, f2), electro (90).control electro-hydraulic (90) establishes the connection between the pressure loading of the system logic of introduction and extraction (77), and one of the elements (55, 64) of the choke control compensator (12).
