Abstract
Abstract An air pump assembly ( 10 ) is provided which has a through flow type air-driving device ( 12 ) supported on an apertured partition wall ( 18 ) with the air-driving device ( 12 ) at one side and the motor ( 50 ) at the opposite side. The wall ( 18 ) is sandwiched between opposed pump and motor housings ( 14 and 16 ) providing complementary ducts ( 27 and 28 ) which communicate with opposed end caps ( 25 and 26 ) mounted on the end walls ( 21 and 22 ) of the pump and motor housings ( 14 and 16 ). The pump housing end wall ( 21 ) is apertured for air flow into the air-driving device ( 12 ) from the end cap ( 25 ) and its side wall supports an air outlet connection ( 13 ). A circuitous inlet passage to the air-driving device ( 12 ) is formed through end cap ( 26 ), ducts ( 27 and 28 ) and end cap ( 25 ). A circuitous outlet passage is formed from the air-driving device ( 12 ) through the motor housing ( 16 ), apertured partition wall ( 18 ) and motor housing ( 16 ).
