Title:
FLUID CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/013390
Kind Code:
A1
Abstract:
Provided is a fluid control device capable of configuring a compact active valve at low cost and easily timing operations of the active valve and a pump even when a high-frequency drive is performed.
A fluid control device (10) is provided with a casing (11) that has a pump chamber (15) and a first flow channel hole (16) communicated with the pump chamber (15), a vibration unit (12) that generates a variation in inner pressure in the pump chamber (15) by vibrating, a valve element (13) that is supported so as to be freely elastically displaced between a position near an opening portion of the first flow channel hole (16) and a position far from the opening portion of the first flow channel hole (16), and a control unit (14) that switches a drive frequency of the vibration unit (12) between a low-frequency side frequency with respect to a structural resonance frequency of the valve element (13) and a high-frequency side frequency with respect to the structural resonance frequency of the valve element (13).
