| 94 | Fluid compressor | US339982 | 1989-04-18 | US5032056A | 1991-07-16 | Nicholas Black; Peter J. Taylor |
| A fluid compressor comprises a casing containing liquid and having located within it a shaft driven radial impeller for pressurizing the liquid before it is fed to a further rotatable structure. By rotation of the impeller and the further rotatable structure, the high pressure liquid compresses a gas or vapor within the compressor casing and expels it from the casing through an outlet port therein. The high pressure liquid inlet end of the rotatable structure is partially shrouded by a shroud structure to restrict the input of high pressure liquid to part of the rotatable structure. The shroud structure has an opening therein which allows the high pressure liquid entering the rotatable structure to be depressurized and returned to the inlet end of the radial impeller after compressing the gas or vapor. By so doing, further gas or vapor for compression will be drawn into the compressor casing. | ||||||
