ABSTRACT:
A hydraulic control system of a transport vehicle, wherein the flow of hydraulic fluid from the source of pressure is fed to the servomotor through a control hydraulic circuit which incorporates a fluid directional control device mechanically linked to a steering unit of a transport vehicle, a number of hydraulic lines and at least one throttle regulator, and through the actuating hydraulic circuit which incorporates a number of hydraulic lines, a throttle regulator and a discrete-type three-position fluid directional control device controlled by a pressure of the fluid flows admitted along the hydraulic lines communicated with the fluid directional control device of the control hydraulic circuit. The throttle regulator of the actuating hydraulic circuit is situated in a hydraulic line thereof before its connection to the inlet of the fluid directional control device, whereas the control hydraulic circuit is connected to the hydraulic line of the actuating hydraulic circuit on its portion located between the inlet to the fluid directional control device and the throttle regulator of the actuating hydraulic circuit.
