Flow rate control apparatus

摘要

A flow rate control apparatus is constructed by integrally assembling a pulsation-attenuating mechanism (24) for balancing a regulated pilot pressure from a pressure-regulating section (54) and a primary pressure of a pressure fluid flowing through a fluid passage (36) to attenuate pressure fluctuation caused by pulsation of the pressure fluid, and a flow rate control mechanism (26) for controlling a flow amount of the pressure fluid flowing through the fluid passage (36) by adjusting a valve lift amount of a valve plug (102) with a linear actuator (112) controlled based on a rotary driving control signal from a controller (118).
