Definitions

  • the invention relates to a pump for pumping of the majority of pumpable substances/medium by the use of rotatable vanes in a pump housing.
  • the medium to be pumped may be in pure state or in a mix of more substances and more aggregate phases such as solid particles, liquids and gaseous matter.
  • WO90/14518A1 relates to a rotary machine with wings extending from a rotor.
  • the pump housing is shaped as half of a cylinder and the rotor is eccentric mounted with its axis outside the center of the pump housing.
  • a number of wings extend from an axle in the rotor towards the inner wall surface of the housing. To force the motion of the wings the wings have guiding pins fitting in guiding slots in the end wall of the rotary machine.
  • US2443994A cover a rotary machine as well, with wings with guiding pins.
  • the pump housing is circular and the rotor is mounted with its axis outside the center of the pump housing.
  • the wings extend from an axis core to the inner wall surface of the pump housing. The forced motion of the wings results in continuous contact with the pump housing.
  • DE3108819A1 cover a similar rotary machine with a circular housing, wings which have a minor extend than the radius of the pump housing, forced motioned bye guiding grooves or magnetism.
  • GB262344A relates to a rotary machine comprising a circular or oval shaped pump housing and a number of wings forced motioned by a piston- or a spring arrangement in such way that continuous contact to the pump housing is achieved.
  • Pump vanes or wings that have an extend minor to the radius of the pump housing.
  • the pumps also consist of numerous amounts of movable components.
  • GB1013801A shows a rotary pump with at least two vanes with limited movement in an axle with a slot.
  • the pump is provided with a rotating sleeve with apertures.
  • US2495771A describes a rotary pump with vanes in pump housing, shaped out of roundness with four different radii.
  • the vanes are installed in a way that they may oscillate in a rotor which is eccentric placed.
  • the extent of the vanes is minor to the largest diameter inside the pump housing.
  • the radius of the rotor body is identical to one of the radii in one of the sectors of the pump housing and so forming a sealing zone with a rather long contact area. Parting in such sectors as described in US2495771A may induce undesired high noise and wear inside the pump as well as an uneven flow of the pumped medium.
  • US2352941A and GB534510 describes a rotary pump with vanes in an pump housing out of roundness.
  • the vanes are arranged to oscillate in an eccentric installed rotor.
  • the radius of the rotor body is in at least a sector of the pump housing identical to the radius of the pump housing and forms a sealing zone.
  • the pump housing may have different embodiments with different unround forms, formed by two different radii, or by varying radii as in an Archimedes spiral.

  • the pressure rise at the discharge side of the pump will lead to a slight movement of the rotor and wear damages at diametrical opposite side of the pump housing will occur.
  • the rotor may be slowed down and heat will be generated, and in a worst case the rotor will stop completely.
  • WO97/04216A1 describes a rotary machine for a motor or a pump with two vanes which extend fully across the diameter of a uncircular pump housing.
  • the internal form of the housing is formed by to sectors with constant radius connected by two sectors with varying radius the.
  • the sector with the minor radius has the same radius as the radius of the axle body, and forms a sealing zone.
  • the rotary machine described in WO97/04216A1 may cause undesired noise and abrasion in the rotary machine, and uneven flow of the pumped/driving matter.
  • the pressure rise at the discharge side of the pump will lead to a slight movement of the rotor and wear damages at diametrical opposite side of the pump housing will occur.
  • the rotor may be slowed down and heat will be generated, and in a worst case the rotor will stop completely.
  • a motor or fluid pump of the kind in question mainly comprises a housing having the shape of a straight hollow cylinder comprising two end walls with parallel internal surfaces and an endless wall.
  • a rotary drum having the shape of a cylinder of rectilinear revolution is disposed in the hollow cylinder.
  • the drum is provided with a groove therethrough diametrically and a vane is slidably guided in the groove, extending axially between the end faces of the housing perpendicular to them.

  • the device further comprises a shaft extending coaxially with the rotating drum through one of the end walls of the housing, said shaft being rotatably connected to the drum so that when the shaft and the drum are driven in rotation, the vane rotates with them by being reciprocated relative to the drum so as to push the fluid entering, with increasing pressure, to the output, the device then working as a pump, whereas, when the pressurized fluid is applied to the input of the device, it works as a motor driving the shaft.
  • US5044910 describes a rotary vane machine that has rotable cams between annular rings which are rotable in a housing and vanes which are radially slidable in a rotor, the cams rotably drive the annular rings and prevent the vanes from contacting the inner peripheral surface of the housing.
  • the present invention is a pump with a rotor (10) comprising two or more vanes (12a, 12b, 7) arranged for running with edges (17a1, 17a2, 17b1, 17b2, 7)against a plain inner wall surface (2) in their full axial extent in a rotor housing (1) with a bottom wall (15) and a cap (16) and further arranged with an inlet (7) and an outlet (6), wherein the rotor (10) is arranged on an axle (9) mainly eccentrically placed related to the inner wall surface (2) of the rotor housing (1), wherein each vane (12a, 12b, ...) is arranged to run each in a corresponding diametrical slot (141, 142 ...) in the rotor (10),that each vane (12a, 12b, ...) extend from an end's edge (17a1, 17b1, ...) to the opposite end's edge (17a2, 17b2 ...) substantially across the whole inner diameter ( ⁇ ) of the rotor housing, between two opposite sides of the inner wall surface (2) for all rotation

  • vanes which are the pumping vanes, extend over approximately the entire diameter of the pump housing, regardless of the rotary position of the vanes.
  • the vanes provide for the necessary sealing to prevent backflow of the pumped medium, see Fig. 1 . Due to the design of the pump according to the invention one will have few movable parts, few components that may fail and low risk of wear.
  • a large diameter of the rotor combined with a vane that extend over the entire diameter in the pump housing gives a large contact area between the rotor and the vane, in contrast to pumps wherein the vane only extend from a place between the rotor center and the outer diameter of the rotor, and to the inner surface of the pump housing as shown in e.g. WO9014518 and GB262344 .
  • the large contact area results in reduced local compressive force compared to prior art. Due to the fact that the vanes extend over the entire diameter of the pump housing, it is possible to use the pump without force motioning the vanes.
  • the diameter of the rotor is less than the cylinder diameter of the pump housing. The different is the length of the stroke with addition of a necessary allowance.
  • the rotor diameter may be 100 mm and the cylinder diameter then will measure 120 mm.
  • the maximum stroke length will then be 20 mm.
  • the pump as a rotary machine may be used as a compressor, an extractor, a vacuum pump and a combustion motor among other range of use.
  • the bearing of the axle is a shaft bearing which form an asymmetric extension of the pump housing (1) and formed as one component.
  • the pump comprises in an embodiment mainly of five components, of which three are movable.
  • the maintenance will be very easy. It will be easy to access the components exposed to wear, such as vanes.
  • the rotor housing (1) is cylindrical and the two or more vanes (12a, 12b,...) are rectangular. Such an embodiment of the housing is easy to mill and makes the assembling very easy. One may also imagine that the rotor housing is more or less drum shaped and that the vanes are formed to fit and fill the drum shape of the rotor housing.
  • the components of the pump may be manufactured of for instance metal or ceramic material depending of the range of use.
  • the cross section of the so formed cylindrical pump housing will not have a real mathematic center point.
  • the housing, the cylinder will in this embodiment be egg- or heart- shaped. At 0 and 180 degrees the transitions may be smoothened to prevent strokes to the vanes at those points.
  • the rate, Delta R is 1/10 mm per degree and R 0 is 50 mm, or R 0 is 460 mm and the rate 80/180 mm per degree, or R 0 is 25 mm and the rate is 1/20 mm per degree according to the below table.
  • the cross section of the rotor housing does not have a real center.
  • the geometry of the inner walls will be defined as e.g. described in claim 2.

  • the vanes (12a,12b,...) are provided with corresponding recesses (13a, 13b, ...) arranged for mutual translational motion within the slots (141, 142) of the rotor (10).
  • This allows the use of more vanes which extend over the entire pump housing diameter and are arranged in the rotor that are located outside the approximate center point of the center of the pump housing.
  • the cylindrical pump housing has no real axis of revolution but only an approximate circular form of the cross section.
  • the rotor has in an embodiment a minor radius to the smallest diameter of the pump housing. In such an embodiment the rotor will not form a sealing zone to the cylindrical inner wall in the pump housing.
  • the rotor is in this embodiment arranged with an allowance to the housing, see Fig.
  • the vanes will travel independent of each other trailing the inner wall of the pump housing.
  • the vanes will be identical and arranged 180 degrees to each other and crossing inside the rotor slots.
  • a conduit internally in the slots in the rotor allows transport of fluid across the vanes so as for the vanes to slide easily and prevent mechanical locking or jamming by the liquid pressure when moving the vanes. This may be done by not letting the recesses tighten onto each other.
  • the vanes are arranged with guiding pins (11) arranged for running in guiding tracks (8) in at least the bottom wall (15) or the cap (16) in the rotor housing (1), wherein the guiding slots (8) are arranged to guide the vanes (12a, 12b, ...) to run near the cylindrical inner wall surface (2).
  • the guiding arrangement comprising guiding pins and guiding slots may be arranged as e.g. ball-bearing to reduce the risk of wear. Oil or another type of lubricant may also be used to the risk of wear. Such force motioning will guide the vanes to trail the cylinder wall.
  • the inlet (7) is arranged radial. In another embodiment of the invention the inlet (7) is arranged parallel with the axle. In an embodiment of the invention the outlet (6) is radial. In another embodiment of the invention the outlet (6) is parallel with the axle.

Outside the outlet (6) and inlet (7) there will be pipe fittings or connections to a pipe manifold according to the requirements. It is important that at least one of the vanes always work as a sealing between the inlet and the outlet as shown in Fig. 1 . Therefore, in a preferred embodiment there will be two or more vane plates.
  • the pump housing comprise a cap.
  • the cap may have a hole for a guiding pin at the top to secure the correct positioning of the guiding slots in the bottom and the cap during assembling, so as for correct guiding of the rotation of the vanes.
  • the cap may have a hole near the center of the rotor so as for connecting two pumps to e.g. a combustion engine or other ranges of use.
