Title:
ELECTROMAGNETIC PUMP
Document Type and Number:
Japanese Patent JP2016098718
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an improvement technology regarding positive drive of an oscillator in an electromagnetic pump.SOLUTION: An electromagnetic pump 100 includes: electromagnets 120, 130; an oscillator 140; and a diaphragm mechanism part 150. Between the oscillator 140 and the electromagnets 120, 130, projection parts 125, 135 projecting toward the oscillator 140 from end surfaces 122a, 132a of electromagnet cores 122, 132 are arranged. Thereby, even when the oscillator 140 is moved by a magnetic force of the electromagnet 120 or the electromagnet 130 so as to be close to the electromagnet core 122 or the electromagnet core 132, surface contact between the oscillator 140 and the end surfaces 122a, 132a of the electromagnet cores 122, 132 is avoided.SELECTED DRAWING: Figure 3
