Definitions

  • the invention relates to a variable-speed vane pump according to the preamble of the main claim.
  • Generic vane pumps are previously known from the document DE-OS 2 015 744 In this type are in radial slots of a rotor in one Housing is mounted, wings are slidably mounted, the outer Slide the ends in a cam ring that includes the wings.
  • the cam ring can be pushed in a housing - see Fig. 4 - or one-sided in one stationary bearing point of the housing can be pivoted - see FIG. 2 - and will be each pushed towards maximum funding by spring force.
  • the flow is deflected in a radial direction on the cam ring adjacent space of the conveyor housing.
  • a disadvantage of this embodiment is that the area of overflow from below Delivery pressure of standing oil from the cam ring to the housing only via gap cross-sections is sealed.
  • the invention is based, for a volume-adjustable vane pump the task to create an actuator assembly for the cam ring that is mechanically compact and is designed with low friction and in which the flow rate appropriate to the operating state, e.g. B. for the lubrication of an internal combustion engine is adjustable.
  • FIG. 1 shows a vane pump 1 designed according to the invention.
  • vanes 5 can be pushed arranged arranged.
  • the outer ends of the wings 5 slide in the inner contour 6 of a cam ring 7, the Delivery chamber 8 with variable delivery chambers 9 forms.
  • the lifting ring 7 can be pushed in the housing 10 - see FIG. 1 - or on one side in one Fixed bearing 15 of the housing 10 can be pivoted - see FIG. 2.
  • variable delivery chambers 9 are in a generally known manner in suction and Conveying process with axial suction or pressure slots or pockets in the housing 10 in Connection, not shown.
  • the cam ring 7 On its circumference, the cam ring 7 is sealed on one side with respect to the housing 10. It forms a hydraulic active surface 7P, which in the pressurized state on an actuating device 11 with sliding and / or counter-mounted in the housing 10 rotatable curve 12 presses. The interior of the housing 10 with the actuating device 11 is relieved of pressure.
  • the rotatable and / or pushable curve 12 in the housing 10 is mounted with a Actuator 13 connected to initiate a rotational and / or pushing movement direct - Fig. 2 - or indirect - Fig. 1 - one acting in the maximum promotion position Spring force F on which, when the actuator 13 is not effective, the cam ring 7 via the curve 12 in pushes a position of maximum promotion and, as shown in both figures, holds.
  • the actuator 13 shifts the curve 12 relative to the support point A7 of the cam ring 7 counter to or in the direction of the acting spring force F as a function of control signals S13 of a pressure control circuit 30, not shown in FIG. 1.
  • the actuator 13 can be an electromagnet, an electrical, hydraulic or be a pneumatic servomotor, which is controlled directly or indirectly by the Pressure control loop 30 takes place. 2 and 3, a hydraulic servomotor is shown.
  • the adjusting device 11 has a rotatable curve 12 on that via a gear and one of the actuator 13 or the acting spring force moving rack is rotated.
  • the opposite curve 12 in the housing 10 can be against the reaction force of the Hubring 7 directed hydrostatic support arrangement 20, for. B. one shown in FIG. segment-shaped pocket 21 acted upon directly or indirectly by the delivery pressure, exhibit.
  • the lifting ring 7 can have a roller or ball arrangement 23 the sliding and / or rotatable curve 12 supported in the housing 10 his.
  • the bearing point 15 is designed as a semicircular trough 18, the has Lifting ring 7 on a complementary bearing segment 73, which by the forces acting on The cam ring 7 is pressed into the bearing recess 18.
  • the cam ring (7) is in the area of its design Swivel axis (SA) in a deflection space (16) radially adjacent to the delivery space (6) located axially with a large cross section to a delivery channel 17 in the housing 10 connected is.
  • SA Swivel axis
  • the delivery chamber 8 in the lifting ring 7 is via radial inlet and outlet cross sections 71 connected to the deflection space 16.
  • the angle of extension of the radial Outlet cross sections 71 in the delivery chamber 8 is less than the extension angle of additional radial overflow channels 72, which are located on both sides of the inlet or Extend outlet cross sections 71. With these overflow channels 72 another Inlet and outlet angle range guaranteed, but the tread in the cam ring 7 less diminished.
  • a pressure element 19 which is mounted in the housing 10 and which can act with spring force or delivery pressure.
  • a spring 19 F which is mounted in the housing 10, presses the pressure piston 19 D non-positively on the cam ring 7. It is also conceivable for the pressure piston 19 D to be supplied with the conveying medium, preferably with the conveying pressure P F , and to engage the cam ring 7 in a force-fitting manner; however, this is not shown.
  • the actuating device 11 can then without disturbing hydraulic Attack the action on the cam ring 7.
  • the inflow and outflow to and from the conveying chambers 6 in the lifting ring 7 can be carried out in the usual way Way over axially or radially opening channels.
