#$%^&*AU2009200357B220131024.pdf#####ABSTRACT A flow generator (4) for generating a flow of pressurized breathable gas includes a cylindrical housing (24, 34) and a motor (44) supported in the housing (24, 34). The motor (44) has a shaft (45) having a first end and a second end opposite the first end. The shaft (45) is generally coincident with an axis of the motor (44). A first impeller (36) is attached to the first end of the shaft (45) and a second impeller (42) is attached to the second end of the shaft (45). A stator (38) directs an air flow from the first impeller (36) back toward the axis of the motor (44). The housing (24, 34)includes an inlet (26) adjacent the first end of the shaft (45) having an inlet axis generally coincident with the motor axis and at least one outlet (28, 30) between the first and second impellers (36, 42). The at least one outlet (28, 30) has an outlet axis generally tangential to the motor axis. An apparatus for delivering a flow of pressurized breathable gas to a patient includes a flow generator (4) and a casing (6) to contain the flow generator. The casing is configured to engage a part of the patient's body, e.g. the top of the patient's head or receive a strap (72, 92) adapted to encircle the patient's arm or chest. The apparatus further includes at least one delivery conduit (8, 74) to convey the flow of pressurized breathable gas and a patient interface (10) to receive the flow of pressurized breathable gas from the at least one delivery conduit (8, 74) and deliver it to the patient's airways. 201/15 4 6 12 10 Figure 1
