ABSTRACT:
A hydraulic machine comprising a rotor concentrically supported in a fluid hamber of the housing wherein upper and lower annular fluid spaces defined between the rotor and housing include upper cavity regions formed radially adjacent the rotor axis and lower cavity regions declined radially therefrom. Fluid supply ports in the upper cavity regions of the annular spaces permit flow of a relatively low density pressurized fluid into the annular spaces to control the level of pumped fluid therein and seal elements span the upper regions of the annular spaces for maintaining pressure differentials between the annular spaces and fluid passages of the housing. Clearance gaps, defined by circumferential edges of the rotor and adjacent surfaces of the fluid chamber, radially bound the lower cavity regions of the annular spaces for limiting the flow of pumped fluid into and out of the annular spaces.
