Abstract (en)
[origin: EP0719947A2] The system incorporates a feedback device (17) to create a feedback force corresponding to the flow volume or to the regulated displacement of the hydraulic pump (1), and which acts upon the valve body (22). The feedback force alters the pressurisation of the valve body through the opposing force, and with it the set point adjustment of the control valve (16) in the opposite direction to the change of the flow volume or displacement.
