To increase the quantity of flow for the piezoelectric pump with single input channel and single output channel of Y type, a valveless piezoelectric pump with double input channels and double output channels in Y type is presented. The design and working principle of the pump are described. The central displacement of the actuator and the volume variation for the pump are analyzed according to the dimensions, coordinates and the mechanical model of the piezoelectric vibrator. The quantity of flow for the double Y channel piezo- pump is calculated and contrast experiments for the single and double Y channel piezo- pumps are presented. Both theoretic and experimental results have shown that the efficiency and flow rate of the double Y channel piezo-pump are greater than those of the Y single channel pump.
