Hydraulic system with hydraulic accumulator - closing pressure established by inflow of control oil from hydraulic accumulator, and restrictor is installed in flow path of control oil from accumulator to control chamber of pump circulation valve
摘要
<p>The closing pressure is established by inflow of control oil from the hydraulic accumulator (15). A restrictor (39) is installed in the flow path of the control oil flowing from the accumulator to the control chamber (24) of the pump circulation valve. The directional control valve (30) in its first position shuts off a control oil line (34) through which an inflow of control oil from the accumulator to the control chamber of the circulation valve takes place when the control valve is in its second position, and connects the control chamber to the reservoir (11).</p>
