Diffuser having ribbed vanes followed by full vanes

Abstract: An improved diffuser is provided for centrifugal compressors and the like. In the improved diffuser, ribbed vanes are aligned with the log spiral core flow within the diffuser and are located radially inwardly of full vanes on a fixed or variable width diffuser.

Vacuum cleaner having an impeller and diffuser

Abstract: A vacuum cleaner blower assembly has a blower motor (81), a vaned centrifugal impeller (90) driven by the blower motor (81) and an air diffuser (89) radially beyond the periphery of the impeller. In order to improve air flow efficiency at the impeller inlet and outlet, the air diffuser (89) has vanes (94) with an inlet angle in the range 1 to 4°.

Gas turbine engine compressor assembly

Abstract: A compressor assembly (12,13) for a gas turbine engine (10) comprises a centrifugal compressor (12) having a variable cross-sectional area diffuser (13) located at its downstream end. When the cross-sectional area of the diffuser (13) is less than a maximum value, some of the air exhausted from the downstream end (24) of the compressor (12) is directed to the upstream end (23) thereof. Sufficient air is so directed as to ensure that the mean air velocity at the outlet (30) of the diffuser (13) remains substantially constant.

Gas generator for an air bag and air bag system

Abstract: A gas generator for an air bag, in which conduction of heat generated by combustion of a gas generating agent is restricted to effectively reduce or inhibit a temperature increase of a diffuser side on an outer shell container, is provided and thus, reduces the maximum surface temperature of the diffuser. The gas generator includes a housing which has a diffuser shell with at least one gas discharge port and a closure shell for forming an accommodating space together with the diffuser shell and the gas generating agent, installed in the housing, ignited and burnt by an igniting unit to generate a combustion gas, wherein the gas generator further includes a heat transfer restricting member for making a conduction of heat generated by a combustion of the gas generating agent to the diffuser shell side smaller than that to the closure shell side.
