Title:
ELECTROMAGNETIC COMPRESSOR
Document Type and Number:
Japanese Patent JP3765720
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an air-feeding electromagnetic compressor enhancing the magnetic efficiency of a magnetic circuit to achieve miniaturization of a pump for economy, while also providing increased durability and enabling delivery pressure flow rate to be controlled in proportion to the amount of electric power generated by a fuel cell.
SOLUTION: The electromagnetic compressor for use as a displacement type cross flow pump, in which an electromagnetic plunger 12 supported under pressure between two of upper and lower springs and having a built-in check valve mechanism having a valve element 19 pressed and closed against a valve seat 20 by a valve spring 18 is slidably and reciprocably actuated within the stand column cylinder 25 of a solenoid coil by intermittent magnetic attracting forces, includes an annular magnetic pole 26 and an annular magnetic path 27 which are positioned at the axial end positions of the electromagnetic coil 10 and fitted over the stand pipe cylinder. A plunger ring 13 in the form of a piston ring made from a fluororesin is fitted into an annular groove cut in each end of the electromagnetic plunger while leaving the outer peripheral edge of an annular strip intact, with the annular groove when in a stationary condition having a magnetic clearance g between the end face of the magnetic pole 26 and the end of the plunger 12 opposite thereto.
