<P>PROBLEM TO BE SOLVED: To provide a pump and a liquid fuel feeding mechanism using the pump having long service life and capable of increasing discharge amount of fluid and of completely preventing a backflow of the fluid. <P>SOLUTION: In this pump 1, magnetic flux generated by carrying a current in a coil 4 acts on magnetic flux of a magnet 3 to enable vibration of the coil 4. A pump chamber 8 is provided with a suction part having a first valve 9a capable of sucking fluid and a discharge part having a second valve 11b capable of discharging the sucked fluid. When the coil 4 is vibrated by carrying a current in the coil 4, a diaphragm 6 is vibrated, and the pump chamber 8 repeats expansion and contraction and sucks fluid via the first valve 9a of the suction part. The sucked fluid can be discharged outside via the second valve 11b of the discharge part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
