摘要： An airfoil diffuser for a centrifugal compressor formed by a diffuser passage area and a plurality of diffuser blades located within the diffuser passage area. The diffuser passage area is defined between a hub plate and a shroud of the centrifugal compressor. Each of the diffuser blades has a twisted configuration in a stacking direction as taken between the hub plate and an outer portion of the shroud located opposite to the hub plate. As a result of the twisted configuration, the diffuser blade inlet blade angle decreases from the hub plate to the outer portion of the shroud and solidity measurements at leading edges of the diffuser plates vary between a lower solidity value measured at the hub plate of less than 1.0 and a high solidity value measured at the outer portion of the shroud of no less than 1.0.

摘要： A method and apparatus for introducing a compressed gas into a pressure vessel, for instance, hydrogen into a vehicle fuel tank, in which hydrogen is compressed in an initial and final compressions stages which can be powered by a common source. The initial compression stage can continually operate to compress the gas in a lower pressure storage bank during the time that hydrogen is dispensed to a vehicle fuel tank. In time periods between dispensing, the gas from the lower pressure stage and from the lower pressure storage bank is compressed in the final compression stage and stored in a higher pressure storage bank. When the pressure vessel is to be filled, the compressor compresses the gas from the higher pressure storage bank to fill the vessel.
