Flow generator

A flow generator for generating a flow of pressurized breathable air to be delivered to a patient for respiratory therapy, the flow generator comprising:

• a housing including an air flow inlet, an air flow outlet, and an air flow path from the air flow inlet to the air flow outlet;
• a blower structured to generate the flow of pressurized breathable air to be provided to the air flow path, the blower including an inlet along an inlet side thereof and an outlet along an outlet side thereof;
• and
• a suspension device to support the blower within the housing and provide a pressure seal between the inlet and outlet sides of the blower,
• wherein the suspension device surrounds the blower to enclose or encase the blower, and the suspension device includes opposing suspension walls with respective suspension apertures to accommodate the inlet and the outlet of the blower,
• wherein the inlet and the outlet of the blower and respective suspension apertures of the suspension device are coaxial with one another, and
• wherein the suspension device includes a bellows portion extending radially outwardly from the opposing suspension walls and arranged along a perimeter of the blower to absorb shock applied at least radially to the blower, and the suspension device further includes one or more cones provided to each of the opposing suspension walls and arranged along respective inlet and outlet sides of the blower to absorb shock applied at least axially to the blower.
