    Abstract: A flow rate control apparatus for heavy construction equipment is provided to supply constant flow rate to the actuator by blocking the connection between the outlet side path of the logic poppet and the back chamber with groove and path. A flow rate control apparatus for heavy construction equipment comprises an actuator(13) for option device which is connected to a hydraulic pump(1), a variable control spool(12) installed in the flow path between the actuator and the hydraulic pump, a switching valve(4) switched by the pressure difference between an inlet side path(5) and an outlet side path(6) of the variable control spool, a logic poppet(10) opening and closing a high pressure path(2) with the pressure difference between the high pressure path side pressure of the hydraulic pump and the pressure passing through the switching valve, and a path connecting a groove and an outlet side path(3a) of the logic poppet. When fluid leaks through the sliding surface gap of the logic poppet as the discharge pressure of the hydraulic pump or the temperature of the working fluid increases, the groove and the path block the connection between the outlet side path of the logic poppet and the back chamber.
