Document Type and Number:
Japanese Patent JP2015065778
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain an iron core the cost of which can be reduced while reducing the clearance between the iron cores.SOLUTION: A solenoid pump 50 according to an embodiment has an inner cylinder 11, an outer cylinder 21 forming an annular channel 1 in conjunction with the inner cylinder 11, an inside iron core 12 having a plurality of inside lamination units 13, an outside iron core 22 having a plurality of outside lamination units 23, an inside coil 14, and an outside coil 24. The inside lamination units 13 are provided contiguously to each other in the circumferential direction, each having a planar inside maximum width plate made of steel spreading from the longitudinal direction and the inner surface of the inner cylinder 11 toward the center thereof, and a plurality of inner side plates laminated on the side of the inside maximum width plate, with the radial length of the inside maximum width plate as the longest length. The inside lamination unit 13 has such a cross-sectional shape as the width in the circumferential direction decreases monotonously toward the radial inside.
