By vibrating plate 9 direction distortion left, the smaller volume of pump chamber 12 inside, the air pressure in the pump chamber 12 increases than external pressure, and the umbrella portion peripheral part of expulsion valve 18 leaves a little from next door 11a.
Thus, the fluid in the pump chamber 12 is applied expulsion force, fluid is discharged to the direction of arrow from tap hole 16, is discharged to the outside from exhaust port 19c then.
Because pressure ratio suction chamber 13 height in the pump chamber in this discharge work, therefore, suction valve 17 covers inlet hole 15, prevents that fluid in the pump chamber 12 is to suction chamber 13 side adverse currents.
Pump P of the present invention like this, the conversion synchronization vibration type piston parts 3 with the magnetic pole of electromagnet 6 vibrate vibrating plate 9 simultaneously.By the vibration of vibrating plate 9, the air pressure in the pump chamber 12 raises or reduction than outside, therefore, can make suction valve 17 and expulsion valve 18 reliably workings, for example, can supply with liquid fuel fluids such as methyl alcohol expeditiously to the fuel cell of outside.
In addition, owing to be fixed on the 1st oscillator 3b and the 2nd oscillator 3c both sides' permanent magnet 4 with electromagnet 6 attraction/repulsions, so, even it is little to add to the electric power of coil 7 outward, also vibration at high speed piston element 3 really.
Therefore, can discharge the volume fluid by enough 1 pump chambers.In addition, because pump chamber 12 is 1, so simple in structure and can realize miniaturization.
In addition, in the present invention, adopt the 1st oscillator 3b and two oscillators of the 2nd oscillator 3c to be illustrated, but also can only adopt the 1st oscillator 3b.
Promptly, fixing vibrating plate 9 on the 1st oscillator 3b is installed the 1st oscillator 3b in the end of cylindrical shell 3a, by supply with the electric power of preset frequencies to the electromagnet 6 that is accommodated in vibratile cylindrical shell 3a, cylindrical shell 3a can be independent of electromagnet 6 and vibrate, and makes vibrating plate 9 vibrations.
Such pump P can reduce number of components, and can realize miniaturization only with the 1st oscillator 3b vibration type piston parts 3.
As the use-case that makes of aforesaid pump P of the present invention, recently, be background with environmental problems such as pollution of atmosphere, seek not cause the clean electric power feeding mechanism of environmental pollution.As an example wherein, developing the fuel cell that the methyl alcohol that acts as a fuel by the chemical decomposition reaction can obtain desirable electric power.
Such fuel cell, for example in the multiple fields such as storage battery that automobile is used, its practicability all waits in expectation.In addition, in recent years, the storage battery as portable electric appts is used also produces the new idea that adopts small fuel cell.
In the small fuel cell that such portable electric appts is used, adopt pump P of the present invention, can supply with the fuel that constitutes by fluids such as methyl alcohol at short notice.
As mentioned above, pump P of the present invention is by vibrating cylindrical shell with the conversion synchronization of electromagnet pole, and by the 1st oscillator vibration vibrating plate, suction valve can open and close inlet hole thus, and expulsion valve can open and close tap hole, so can utilize the vibration of cylindrical shell reliably to vibrate vibrating plate.Therefore, by reliable running suction valve and expulsion valve, can be expeditiously to outside supply flow body.
In addition, conversion synchronization ground by the 1st oscillator and the 2nd oscillator and electromagnet pole is adsorbed or repels by electromagnet, make cylindrical shell carry out piston motion and vibrate vibrating plate, so, can make cylindrical shell carry out piston motion by enough permanent magnets that is fixed on the 1st oscillator and the 2nd oscillator both sides, the pump of low power consumption can be provided.
If to the direction of being adsorbed by electromagnet vibration, then because the air pressure in the pump chamber is lower and suck fluid from inlet hole than external pressure, and expulsion valve cuts out tap hole to vibrating plate, so can suck fluid from inlet hole reliably by the 1st oscillator.In addition, owing to close tap hole with expulsion valve this moment, so the fluid of discharging to outside adverse current in pump chamber not.
In addition, if vibrating plate vibrates to the direction of repelling electromagnet by the 1st oscillator, then, and discharge from tap hole, so the fluid that is drawn in the pump chamber can be discharged from tap hole reliably from the fluid that inlet hole sucks because the air pressure in the pump chamber raises and the suction valve closure inlet hole.
In addition, when suction valve and expulsion valve were closed inlet hole and tap hole, fluid is adverse current not, the high efficiency pump that can provide fluid not have to suck loss and discharge loss.
