Positiv-displacement rotary mashine

Abstract

A positive-displacement rotary machine comprises a housing a rotor installed in the housing with the a capability of rotation, a separator installed in the housing, having a guide part with a hole for the rotor; a piston installed in the a groove of the rotor with the a capability of making rotary oscillations relative to the rotor around an axis that intersects the an axis of rotation of the rotor, having at least one slot into which the guide part of the separator enters, a sphere-like working cavity formed around the rotor, which the guide part of the separator, during interaction of the hole with the rotor, divides into chamber-forming cavities of variable cross section, each of which is divided by the piston into working chambers. There is a passage for the a working fluid that permits the working thud to bypass the minimal cross section of the chamber-forming cavity; and input and output ports of the working fluid.

         4 . The positive-displacement rotary machine according to  claim 1 , wherein the piston contains at least one sealing synchronizing element installed in the slot, through which the piston interacts with the guide part of the separator. 
     
     
         5 . The positive-displacement rotary machine according to  claim 4 , wherein the sealing synchronizing element is installed in the piston with the capability of turning relative to an axis perpendicular to the axis of the piston. 
     
     
         6 . The positive-displacement rotary machine according to  claim 1 , wherein the guide part of the separator is installed in the housing at a fixed angle to the axis of rotation of the rotor. 
     
     
         7 . The positive-displacement rotary machine according to  claim 1 , wherein the separator is installed in the housing with the capability of changing a slope of the guide part to the axis of rotation of the rotor to control feed of the machine. 
     
     
         8 . The positive-displacement rotary machine according to  claim 7 , in which wherein the separator changes the slope of the guide part to the axis of rotation of the rotor, by turning around an axis perpendicular in the axis of rotation of the rotor. 
     
     
         9 . The positive-displacement rotary machine according to  claim 7 , wherein the separator is supplemented by a shell with a sphere-like cavity in which guide part of the separator is situated. 
     
     
         10 . The positive-displacement rotary machine according to  claim 9 , wherein the guide part is situated at an angle relatively to the shell and changes the guide part slope to the axis of rotation of the rotor by turning of the shell around an axis passing at an angle to the axis of rotation of the rotor.
