Abstract
Provided is a flow rate regulating device including a valve body section having a flat valve body surface; a main body section including a valve chamber, an inflow channel, an outflow channel, and a communication channel; a valve seat section having a flat valve seat surface provided around an inflow opening; a regulation mechanism that moves the valve body section along an axis to regulate a distance between the valve body surface and the valve seat surface; and a control unit that controls the regulation mechanism so that the valve body section moves in a movement range in which the valve body surface and the valve seat surface maintain a non-contact state, wherein a channel cross-sectional area of the communication channel is smaller than each of a channel cross-sectional area of the inflow channel and a channel cross-sectional area of the outflow channel.
