Title:
ELECTROMAGNETIC AIR PUMP
Document Type and Number:
Japanese Patent JP3358834
Kind Code:
B2
Abstract:
PURPOSE: To prevent loosening from being generated by vibration at the support part of a pump unit which is supported movably on a body casing.
CONSTITUTION: An electromagnetic vibrating element 16 in a pump unit, 10 stored inside body casings 2, 3 is driven by an electromagnet, 9, and air is discharged from a discharge nozzle 33. When a noise eliminating chamber cover 11 is rotated, the pump unit 10 is moved so as to approach and separate from the electromagnet 9 by action of threaded grooves 322, 323, so that air discharge of the pump unit 10 can be adjusted. The pump unit 10 is provided with a pair of upper and lower sliding projections 315, 316 which are slidingly-guided to abrasion-resistant resin guide members 35, 36 formed at the body casings 2, 3.
