Vane machine having stationary and rotating cylinders with reduced clearance

Abstract

Vane machine with rotating cylinder and first and second stationary cylinders with reduced rotating parts clearance working with compressible or incompressible fluid. The first stationary cylinder at its intake and cover has axial canal that takes fluid to the radial opening into the machine working chamber in order to decrease the vane machine diameter.

         2 . The vane machine as claimed in  claim 1  and variant (B), wherein the cylinder rotating parts clearance is deceased by means of bearings positioned between the stationary cylinders (A 1 ) and (A 2 ); the bearings are pulled over common additional ring ( 9 ) with raised shroud ( 10 ) between the bearing inner rings ( 8 ); spiral spring ( 12 ) is placed around the shroud ( 10 ); between the bearing outer rings ( 7 ) is placed fixed distancer ( 13 ). 
     
     
         3 . The vane machine as claimed in  claim 1  and variant (B 1 ), wherein the cylinder rotating parts clearance is deceased by means of two high precision bearings, positioned between the stationary cylinders (A 1 ) and (A 2 ); the bearings are pulled over common additional ring ( 16 ); between the bearing outer rings ( 14 ) is placed fixed distancer ( 13 ). 
     
     
         4 . The vane machine as claimed in  claim 1  and variant (B 2 ), wherein the cylinder rotating parts clearance is deceased by means of two bearings, positioned between the stationary cylinders (A 1 ) and (A 2 ); the bearings are by their inner rings ( 8 ) pulled over flat additional ring ( 17 ); between the bearing outer rings ( 7 ) there is fixed distancer ( 13 ). 
     
     
         5 . The vane machine as claimed in  claim 1  and variant (B 3 ), wherein the cylinder rotating parts clearance is deceased by means of two bearings, positioned between the
 stationary cylinders (A 1 ) and (A 2 ); the bearings are by their inner rings ( 8 ) pulled over flat additional ring ( 18 ); the bearings have raised shoulder ( 19 ); between the bearing outer rings ( 7 ) there is fixed distancer ( 13 ). 
 
     
     
         6 . The vane machine as claimed in  claim 1  and variant (B 4 ), wherein the cylinder rotating parts clearance is deceased by means of additional ring ( 20 ) with raised shoulder ( 21 ); the additional ring ( 20 ) has fixed outer distancer ( 22 ) on which rotates rotating bearing ( 23 ) with spring; the bearing ( 25 ) with spring rotates on lateral holder ( 24 ); the bearing ( 27 ) with spring rotates on lateral holder ( 26 ); the additional ring ( 20 ), the lateral holders ( 24 ) and ( 26 ) and the fixed outer distancer ( 22 ) are positioned between the stationary cylinders (A 1 ) and (A 2 ). 
     
     
         7 . The vane machine as claimed in  claim 1  and variant (B 5 ), wherein the cylinder rotating parts clearance is deceased by means of rotating part ( 54 ) and stationary part ( 55 ), positioned between the stationary cylinders (A 1 ) and (A 2 ); through the stationary part ( 55 ) is made pressurised working fluid intake canal ( 56 ) and pressurised fluid exhaust canal ( 57 ). 
     
     
         8 . The vane machine as claimed in claim wherein it has stationary cylinders (A 3 ) with compression sliding regulators (G); the compression sliding regulators (G) are placed in the stationary parts of the cylinders (A 3 ); in the stationary part of the cylinder (A 3 ) is pressurised working fluid radial exhaust opening ( 6 ); the radial opening ( 6 ) is narrower than radial opening ( 5 ) taking the working fluid in; the working fluid exhaust ( 6 ) and intake ( 4 ) are connected by a canal in which moves the compression sliding regulator (G), that changes the compression ratios in the machine; the working fluid is changed automatically at the vane machine exit so that pressure at the machine exit is higher than pressure in the pressure system, this requiring lesser power for compression. 
     
     
         9 . The vane machine as claimed in  claim 1 , wherein the rotating cylinder with decreased rotating parts clearance is positioned between the stationary cylinders (A 4 ) in which are made canals ( 58 ) distributing the pressurised fluid. 
     
     
         10 . The vane machine as claimed in  claim 1 , wherein the rotating cylinder with decreased rotating parts clearance is made with rotor (C 1 ); the said rotor has rotating shafts ( 48 ) with bearings ( 49 ); the bearing ( 49 ) is inserted into opening ( 50 ) in lateral plate (P 2 ); the said rotor has vanes (E 1 ) with additional shafts ( 52 ) with bearings ( 53 ); the bearings ( 53 ) move in slots ( 51 ) in the lateral plates (P 2 ). 
     
     
         11 . The vane machine as claimed in  claim 1 , wherein rotating plate variant (P 1 ) on the rotor has radial openings ( 31 ) taking the working fluid to covers (D); the openings ( 31 ) are connected by canal ( 41 ) with opening ( 5 ) supplying the working fluid aimed to maintaining the working fluid intake pressure below vane (E).
