Abstract (en)

[origin: WO2012145166A1] A liquid dispenser (310) includes a substrate (339 ). A first portion of the substrate defines a liquid dispensing channel (312) including an outlet opening (326). A second portion of the substrate defines an outer boundary of a cavity(390). Other portions of the substrate define a liquid supply channel (311) and a liquid return channel (313). A liquid supply(324) provides a continuous flow of liquid from the liquid supply through the liquid supply channel through the liquid dispensing channel through the liquid return channel and back to the liquid supply. A diverter member (320) is selectively actuatable to divert a portion of the liquid flowing through the liquid dispensing channel through outlet opening of the liquid dispensing channel. The diverter member includes a MEMS transducing member. A first portion of the MEMS transducing member is anchored to the substrate. A second portion of the MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. A compliant membrane (130) is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member. A second portion of the compliant membrane is anchored to the substrate such that the compliant membrane forms a portion of a wall of the liquid dispensing channel. The wall is positioned opposite the outlet opening.
