ABSTRACT:
Disclosed is an electric air pump assembly and a sub-assembly for use therein which speeds assembly and assures proper alignment of the operative pump parts to facilitate proper pump operation while minimizing fatigue failures due to misalignment.
The electric air pump assembly (10) is of the type comprising a housing (20) enclosing at least one diaphragm pump (30) having a base (31) and a reciprocable diaphragm (32), an actuator arm (40) affixed to the diaphragm at a location between the two ends of the arm, pivot means (61) for supporting one end (43) of the arm, and electromagnet means (50) operable to reciprocate the unsupported end (41) of the arm and thereby cause the arm to reciprocate about the pivot means and effect reciprocating movement of the diaphragm which in turn creates an air flow from the pump. Alignment means (60) are provided for aligning the actuator arm and the diaphragm within the housing, the alignment means being attachable to the housing and being integral with both the diaphragm pump base and the pivot means.
