<p>Disclosed is a variable regeneration valve (RV) of a heavy equipment in which hunting due to repeated motion of a spool does not occur in a regeneration valve that supplies a return flow of an actuator to a supply port during single operation of the actuator or its composite operation such as composite driving of arm in and swing, and a structure of the variable regeneration valve is simplified to improve process characteristics. The variable regeneration valve includes a hydraulic pump, an actuator (c) connected with the hydraulic pump, a control valve (AV) controlling operation, stop, and direction of the actuator, a regeneration switching valve (RV) having a first piston, a switching spool, a first elastic member, and a second piston, a first damping orifice, and a second damping orifice.</p> |
