ABSTRACT:
An air controller for an air pump capable of simply regulating the air delivery rate of the air pump. In an air pump including an electromagnetic driving mechanism 11, 13, 14, a magnet 17 carried on the tip of an arm 16, and a diaphragm 18 connected to the intermediate portion of the arm, the magnet being reciprocated by an electromagnetic action exerted between the electromagnetic driving mechanism and the magnet, the intake and discharge action being effected by the expansion and contraction of the diaphragm, the improvement lies in that the electromagnetic driving mechanism is mounted on a housing in such a manner that it is capable of advancing and retreating with respect to the magnet, whereby the advancement and retreat of the electromagnetic driving mechanism will cause the distance between the core 13 and magnet 17 and hence the reciprocating rate of the magnet to change, thus accomplishing the change of the air delivery rate.
