ELECTROMAGNETIC PUMP
Document Type and Number:
Japanese Patent JP3422898
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a miniaturized electromagnetic pump.
SOLUTION: This electromagnetic pump is constituted to be furnished with a main body case 1 on one side of which a compressor 22 provided with a diaphragm 40 and an iron core storage chamber 15 surrounded by a peripheral wall are provided, a pair of laminated iron cores 30 consisting of a yoke part 31a on which a driving coil 32 is installed and magnetic poles (central magnetic pole 31b, side magnetic pole 31c) and stored in the iron core storage chamber 15 by separating the respective magnetic poles from each other and making them face against each other and an oscillator 50 installing a support shaft (screw 53) provided on an end part on the diaphragm 40, arranged between the aforementioned both magnetic poles and furnished with a permanent magnet 52. In this case, the main body case 1 is made into divided cases 11 by dividing it at a portion of the iron cor storage chamber 15 in a direction orthogonal with the oscillating direction of the oscillators 30, and both of the divided cases 11 are connected to each other by storing the laminated iron cores 30 in the iron core storage chamber 15 of these divided cases 11.
