Flow path adjustment mechanism and fluid delivery device

Abstract

A flow path adjustment mechanism of a fluid delivery device is able to adjust a flow area of a fluid flowing by driving of a driver. The flow path adjustment mechanism includes a shielding assembly to adjust shielding and opening of at least a portion of a flow surface of a flow path as viewed from a flow direction of the fluid based on a detection result of at least one of a driving state of the driver and a state of the fluid in the flow path through which the fluid flows. The fluid delivery device includes the flow path adjustment mechanism and a flow device. The flow device causes the fluid to flow by driving the driver.
