  • Patent number: 9334736
    Abstract: A rotary fluid machine 10 has a rotor 12, a stator 14, and a plurality of gates. The rotor 12 and stator 14 are rotatable relative to each other and arranged one inside the other to define a working chamber 18 there between. Gates 16 are supported in radial gate slots 20 formed in the rotor 12 and cyclically extend from and retract into the gate slots 20 as the rotor 12 rotates about stator 14. A plurality of demountable lobes is supported on an outer circumferential surface 24 of stator 14. The surface 24 forms a surface of the working chamber 18. Circumferential surface 24 is composed of an intermediate surface 48 which extends in an axial direction and opposite curved surfaces 46. The gate 16 has opposite rounded corners 130 separated by an axial planar surface 132.

  • Patent number: 8529222
    Abstract: A surface pump assembly having a thrust chamber with a telescoping shaft. In some embodiments, the surface pump assembly has a pump with a pump shaft, a thrust chamber with a telescoping shaft extending therein, the telescoping shaft extendable to engage the pump shaft and retractable to disengage the pump shaft, and a motor coupled to the telescoping shaft and operable to rotate the telescoping shaft. In some embodiments, the telescoping shaft has a rotatable shaft member, an adjusting nut threadably disposed thereabout, wherein the adjusting nut is moveable axially relative to the shaft member by rotation, and a first sleeve translatably disposed about the shaft member.
