Pump or motor

Abstract

The invention relates to a pump or motor for liquid or gaseous media. The pump or motor has a shaft, which faces a working part, and has a common inclined sliding surface with the working part. The working part which limits the pump working chambers, wobbles in a positionally fixed housing.

1 - 17 . (canceled) 
     
     
         18 . A pump or motor for liquid or gaseous media, comprising:
 work chambers disposed between two diametrically opposed work faces that are symmetrical to respective axes of rotation of the two work faces;   one spur toothing on each of the two work faces, the spur toothings associated with one another of which, together with radially extending meshing lines of contact, define the work chambers;   a defined corresponding angle between the respective axes of the two work faces,   a working part having a spur toothing for receiving one of the work faces, the working part being rotatable about its axis;   a spherical radial boundary of the working part and of the work faces for sealing support on a partly spherical inner wall of a housing;   a radial boundary of the work chambers, by which boundary the partly spherical inner wall surrounds the working part, on which wall the working part can tumble about its axis and is supported radially sealingly on the wall;   a rotary drive or power takeoff via a shaft; and   one conduit forming one inlet and one conduit forming one outlet to the work chambers for the media, wherein between the shaft and the working part that is provided with a spur toothing and a work face, a slanted sliding plane is disposed, so that   rotation of the shaft leads to tumbling of the working part, and tumbling of the working part leads to rotation of the shaft, and   the work face, diametrically opposite the working part and having a spur toothing corresponding to the spur toothing of the working part, is disposed as non-corotating and is thus disposed as a stationary work face in the housing.   
     
     
         19 . The pump or motor as defined by  claim 18 , wherein a center axis of the stationary work face is identical to the axis of rotation of the shaft. 
     
     
         20 . The pump or motor as defined by  claim 18 , wherein the partly spherical inner wall that receives the tumbling working part changes over into a cylindrical opening in the housing the diameter of which is equivalent to the diameter of the working part. 
     
     
         21 . The pump or motor as defined by  claim 19 , wherein the partly spherical inner wall that receives the tumbling working part changes over into a cylindrical opening in the housing the diameter of which is equivalent to the diameter of the working part. 
     
     
         22 . The pump or motor as defined by  claim 18 , wherein the machine has cylindrical outer dimensions for installation in bores or pipelines. 
     
     
         23 . The pump or motor as defined by  claim 19 , wherein the machine has cylindrical outer dimensions for installation in bores or pipelines. 
     
     
         24 . The pump or motor as defined by  claim 18 , wherein a peg is disposed between the working part and the shaft on the slanted sliding plane and engages a corresponding guide bore of the diametrically opposed part of the working part or the shaft. 
     
     
         25 . The pump or motor as defined by  claim 24 , wherein the peg ( 26 ) is disposed on the working part. 
     
     
         26 . The pump or motor as defined by  claim 18 , wherein the shaft ( 4 ) including the working part is loaded resiliently in the direction of the stationary work face; and that the shaft is supported in a total housing rotatably and axially displaceably. 
     
     
         27 . The pump or motor as defined by  claim 18 , wherein between the working part and the diametrically opposed, non-corotating work face, a common spherically embodied bearing surface is centrally present, which likewise serves the purpose of radially defining the pump work chambers. 
     
     
         28 . The pump or motor as defined by  claim 18 , wherein the teeth of the diametrically opposed spur toothing are embodied as a cycloid toothing, with a power part and a blocking part with a cycloidal development of the sliding surface. 
     
     
         29 . The pump or motor as defined by  claim 18 , wherein inlets/outlets from the pump work chambers, as static conduits, branch off axially symmetrically from the stationary work face and in a manner uncontrolled by the working part. 
     
     
         30 . The pump or motor as defined by  claim 29 , wherein the static conduits are controllable by valves disposed in the work chamber housing. 
     
     
         31 . The pump or motor as defined by  claim 30 , wherein plate valves, with a mounting part having one outer and one inner ring, and having spring plates disposed between the rings and secured resiliently on one ring thereof, serve as the valves. 
     
     
         32 . The pump or motor as defined by  claim 18 , wherein the shaft has an increased diameter toward the slanted sliding plane; and that corotating conduits acting as an inlet or outlet extend in the step thus formed. 
     
     
         33 . The pump or motor as defined by  claim 32 , wherein openings corresponding to the conduits are present in the work face of the working part and are controlled by the orifices of the conduits in the slanted sliding plane. 
     
     
         34 . The pump or motor as defined by  claim 18 , wherein for carrying the liquid or gaseous media onward from and to the work chambers, the shaft has a connecting conduit, extending in the shaft, in order to avoid radial loads of the shaft to the housing receiving the shaft or to a bearing for the shaft. 
     
     
         35 . The pump or motor as defined by  claim 34 , wherein openings are present on the bottom of the work chambers, which openings lead to a collection chamber that is present between the slanted sliding plane and a back side of the working part, and the collection chamber is closed radially toward the outside and leads directly to the connecting conduit. 
     
     
         36 . The pump or motor as defined by  claim 34 , wherein in a bearing point between the working part and the slanted sliding plane of the shaft, in a region where the media is carried toward the connecting conduit, there are tapered places in the material for mass compensation pertaining to rotary forces. 
     
     
         37 . The pump or motor as defined by  claim 35 , wherein in a bearing point between the working part and the slanted sliding plane of the shaft, in a region where the media is carried toward the connecting conduit, there are tapered places in the material for mass compensation pertaining to rotary forces.
