ABSTRACT:
A flow rate control apparatus is constructed by integrally assembling a pulsation-attenuating mechanism for balancing a regulated pilot pressure from a pressure-regulating section and a primary pressure of a pressure fluid flowing through a fluid passage to attenuate pressure fluctuation caused by pulsation of the pressure fluid, and a flow rate control mechanism for controlling a flow amount of the pressure fluid flowing through the fluid passage by adjusting a valve lift amount of a valve plug with a linear actuator controlled based on a rotary driving control signal from a controller.
