A hydraulic drive of a block-portion separator of pressed forage includes a hydro-tank with working fluid, hydro-pump, hydro-cylinder, hydro-motor and four-way three-position control valve with electro-hydraulic control. Fluid supply under pressure to hydro-motor and hydro-cylinder takes place by means of slide flow divider, and in one of under-end cavities of the slide valve a spring is installed, and the other under-end cavity is connected to pressure hydro-line that connects the outlet of the divider to hydro-motor, the increase of pressure in the cavity increases opening of the throttle window that connects the hydro-motor to the pump. |
