2. a kind of driving method of bending vibration sandwich formula passive-type hydraulic jet propulsion system as described in claim 1, it is characterised in that:
The driving method of the bending vibration sandwich formula passive-type hydraulic jet propulsion system specifically: the valve makes its generation with (1) application is stacked
Shorten the ac-excited electric signal of deformation, so that the volume of valve chamber (6-1) increases, valve is forced to open with umbrella valve (7) at this time, stream
Body flows into valve chamber (6-1) by valve chamber water inlet (6-5)；The valve applies the exchange for making it generate elongation strain with (1) is stacked
Electric signal is motivated, the pump applies the ac-excited electric signal for making it generate a direction bending deformation with driving assembly (10),
So that the volume of valve chamber (6-1) becomes smaller, the volume of pump chamber becomes larger, and valve is forced to be closed with umbrella valve (7) at this time, and pump uses umbrella valve
(8) it is forced to open, fluid flows into pump chamber by pump chamber water inlet (6-6), completes a water absorption course；The pump uses driving assembly
(10) apply the ac-excited electric signal for making it generate other direction bending deformation, so that the volume of pump chamber becomes smaller, pump is used at this time
Umbrella valve (8) is forced to be closed, and fluid is sprayed by water outlet (6-8), completes primary water spray process；
The valve sine wave or square-wave cycle electric signal for stacking that the ac-excited electric signal that (1) passes to is a certain frequency, institute
Sine wave period electric signal of the pump with the ac-excited electric signal that driving assembly (10) passes to for a certain frequency is stated, the valve is used folded
Heap (1) is 180 degree with the phase difference that driving assembly (10) passes to ac-excited electric signal with pump.
