    摘要: Fluid is pressurized and supplied to a fluid chamber with a fluid pressurizing and supplying unit. The pressurized fluid within the fluid chamber is ejected through an injection nozzle by reduction of the volume of the fluid chamber caused by applying a driving voltage to a volume varying unit. In applying the driving voltage to the volume varying unit, the effect imposed on fluid injection by pressure fluctuations of the fluid pressurized and supplied to the fluid chamber is compensated by changing the voltage waveform of the driving voltage. When the pressure of the supply flow amount is decreased to a pressure lower than a predetermined pressure, the time intervals of the driving waveform are corrected. The maneuverability of a fluid injection device does not deteriorate even when the pressure of the fluid pressurized and supplied to the fluid chamber fluctuates.

    摘要: A liquid supply pump includes: three chambers of a first liquid chamber, a second liquid chamber, and a third liquid chamber disposed in series and produced by dividing a space between an inlet channel into which liquid is supplied and an outlet channel from which liquid is delivered; a first movable partition and a second movable partition which section the respective chambers and change the volumes of the chambers; channels each of which penetrates the corresponding one of the first and second movable partitions so that the two adjoining chambers can communicated with each other; and non-return valves each of which opens and closes the corresponding one of the channels. Each of the non-return valves closes when the corresponding movable partition shifts from the inlet channel side toward the outlet channel side, and opens when the corresponding movable partition shifts from the outlet channel side toward the inlet channel side.

    摘要: A fluid feed pump is configured, such that a fluid is fed from an outlet channel of the fluid feed pump through an outlet buffer chamber to a fluid channel. The outlet buffer chamber is designed to have a higher compliance than a compliance of a pump chamber. The driving period of the fluid feed pump is set to a shorter period than a time constant defined by the compliance of the pump chamber and a flow resistance between an inlet of the outlet channel and an outlet of the fluid channel. This enables the fluid to be fed with high efficiency by taking advantage of the pressure oscillation occurring between the pump chamber and the outlet buffer chamber.
