<p>An air pump assembly (10) is provided which has a through flow type air pump (12) supported on an apertured partition wall (18) with the pump (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 pump (12) from the end cap (25) and its side wall supports an air outlet connection (13). A circuitous inlet passage to the air pump (12) is formed through end cap (26), ducts (27 and 28) and end cap (25). A circuitous outlet passage is formed from the air pump (12) through the motor housing (16), apertured partition wall (18) and motor housing (16).</p> |
