摘要： The present invention describes a flow generator for generating a flow of pressurized breathable gas, comprising: a cylindrical housing; a motor supported in the housing, the motor having a shaft having a first end and a second end opposite the first end, the shaft being generally coincident with an axis of the motor; a first impeller attached to the first end of the shaft; a second impeller attached to the second end of the shaft; and a stator that directs an air flow from the first impeller back towards the motor axis, and wherein the housing comprises an inlet adjacent the first end of the shaft and having an inlet axis generally coincident with the motor axis, and at least one outlet between the first and second impellers, the at least one outlet having an outlet axis generally tangential to a circumference of the cylindrical housing, wherein the air flow enters the first impeller and the second impeller in the same direction.
