Document Type and Number:
Japanese Patent JP3485478
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve vibration control and sound proof effect by assembling the bottom part of a case having a bottom to be in upper position so as to increase the rigidity of the case having the bottom.
SOLUTION: This pump is constructed in such a manner that based on magnetic interaction between an electromagnet and a permanent magnet, a diaphragm connected to a vibrator is vibrated by the electromagnetic vibration of the vibrator having a permanent magnet. In this case, the pump is assembled by laminating a case 3 having a bottom for housing an electromagnet 8, a vibrator 10 and a pump casing 18 having a diaphragm 13 and a pump room 16, an air tank 1, a partition plate 2 provided between the case 3 having the bottom and the air tank 1, the bottom part 3a of the case 3 having the bottom is arranged in an upper position.
