Abstract

A blower compressor assembly (402) comprises: a flow modifier (412) comprising an array of nozzle guide vanes (525) and an array of diffuser vanes (515), wherein the flow modifier is movable relative to a rotor (410) between a turbine configuration and a compressor configuration; and an actuator assembly (600) for moving the flow modifier relative to the rotor between the turbine configuration and the compressor configuration, wherein the actuator assembly comprises: a first actuator (610) comprising a first chamber (613), a first valve (616) configured to selectively supply pressurised air to the first chamber (613) or vent pressurised air from the first chamber, and a piston (614) arranged to one side of the first chamber and coupled to the flow modifier such that the flow modifier is moved into the turbine configuration or the compressor configuration based on the pressure of air within the first chamber; and a second actuator, configured to controllably adjust the position of the piston when the blower compressor is in the compressor configuration.
