PROBLEM TO BE SOLVED: To provide an electromagnetic vibration type pump capable of improving pump performance by increasing propulsion force of an oscillator. SOLUTION: This electromagnetic oscillation type pump is provided with electromagnets oppositely arranged in a casing, the oscillator inserted in a gap part between electromagnets and fixing the electromagnets, a diaphragm fixed on left and right end part of the oscillator, and a pump casing part installed on both end parts of the casing. The surface of the electromagnet has a convex shape. COPYRIGHT: (C)2004,JPO |
