Definitions

  • the present invention relates in particular to a control disk for a vane pump according to the preamble of Claim 1.
  • Control discs for vane pumps are in a wide variety Refinements known.
  • DE-196 51 386 a vane pump, which one of a shaft-driven rotor and a cam ring, which is arranged outside the shaft. Between the Several working slides are arranged in the rotor and the cam ring. The rotor and the cam ring are on the sides of each a printing plate limited.
  • DE-OS 2 207 671 describes a vane pump in which a housing outlet grooves are also provided to sudden pressure change in a vane chamber of the vane pump to prevent.
  • a control disk is thus in particular for a vane pump which has a pressure opening, comprises a suction opening and a ventilation device.
  • the venting device is with the pressure opening connected.
  • the venting device as groove-shaped recess or groove in a side surface of the Control disc formed, the groove in one in the Control disc provided through hole ends.
  • the vent path in the vane pump can be adjusted easily Way to be led.
  • the groove is simple and inexpensive can be produced, there are less according to the invention Production costs.
  • the assembly costs be reduced, since no throttle bolt or the like is installed. is necessary as a ventilation device.
  • the risk of chips during the Install the throttle pin in the ventilation path significantly reduced. According to the invention, this can be a reliable Ventilation must be ensured.
  • the groove preferably has a continuous length Cross section change. This allows the groove next to hers Venting function also a throttling effect provide.
  • the cross-sectional area of the groove is preferably continuous.
  • the pressure opening and the suction opening are each arc-shaped or kidney-shaped.
  • the groove is arcuate. This is it is possible that the groove e.g. by means of a driven Tool when turning on a machine, which is necessary anyway will be produced.
  • the groove-shaped recess is linear, i.e. straight and not arched. This makes possible a particularly simple and inexpensive manufacture of the groove-shaped recess.
  • the groove can simultaneously be produced with the pressure opening.
  • the groove runs in the vane pump about a quarter of the circumference of the control disc. This enables quick assembly on the one hand and on the other hand reliable ventilation.
  • a vane pump with a provided as described above control disc According to the invention, a vane pump with a provided as described above control disc.
  • the present invention is not for use limited with vane pumps but can also with others Pumps, which control disks or other side windows have used.
  • the present invention provides a control disc especially ready for vane pumps, which by design a ventilation device as a groove-shaped recess Reliable ventilation guaranteed in a simple manner and the manufacturing and assembly costs the solutions known from the prior art reduced.
  • Figures 1 and 2 is a control disc or a vane pump according to a first embodiment of the presented present invention.
  • the control disk according to the invention comprises 2 a pressure kidney 3 and a suction kidney 4, which as Cutouts are formed on a side surface of the control disk 2 are.
  • a ventilation groove 6 is provided which the pressure kidney 3 with a through hole 5 formed in the control disk 2 combines.
  • the vent groove is such trained that their cross-sectional area based on the pressure kidney 3 to the through hole 5 is continuously reduced.
  • the ventilation groove is arched, the radius center of the groove 6 that of the pressure kidney 3 corresponds.
  • a center hole 15 serves to receive a shaft (see FIG. 2).
  • FIG. 2 is a vane pump 1 with an inventive Control disc 2 shown.
  • the vane pump 1 comprises a drive shaft 11, a rotor 10, several blades (not shown) and a cam ring 9, which in a housing 12 are arranged.
  • a cover 13 encloses these parts of the Vane pump 1 from the other side (see FIG. 2).
  • the slot-shaped chambers of the rotor are over the ring-shaped Groove 7 connected to the pressure kidney 3 of the control disk 2, to push the wings out depending on their position.
  • Fuel is drawn in via a supply channel 14 and then formed in between the rotor 10 and the cam ring 9 Pressure chambers, which are limited by the wings brought a higher pressure level and to a pressure line 16 returned again. Since the vent groove 6 with the pressure kidney 3 is connected, air can also be conveyed via the ventilation groove 6 are discharged and through the through hole 5 to get redirected. Due to the continuously decreasing Cross-sectional area of the vent groove 5 takes place at the venting also simultaneously throttling the discharged Air.
  • FIG. 3 shows an example of a use of the vane pump 1 with the control disk 2 according to the invention in a diesel common rail pump.
  • the diesel common rail pump comprises two pumps, namely the vane pump 1 as a prefeed pump or low-pressure pump and a high-pressure pump 17 which is designed, for example, as a radial piston pump.
  • the vane pump 1 draws fuel from a tank 18, which is passed through a filter 19 in front of the pump 1.
  • the high-pressure pump 17 approximately 1600 • 10 5 Pa to 1800 • 10 5 Pa
  • Figure 4 is a control disc according to a second embodiment of the present invention. Same or functionally identical parts have the same reference numerals as referred to in the first embodiment. Since that second embodiment essentially the first embodiment are only differentiated below described in detail.
  • a groove 6 is which connects a pressure kidney 3 with the through hole 5, linear, i.e. straightforward, educated. This can in particular the tapering of the groove 6 easily and inexpensively getting produced. Otherwise the control disc corresponds to 2 of the second embodiment that of the first embodiment, so that there is no further description can be.
  • the present invention relates to a control disk 2 especially for vane pumps which one Has suction opening 4 and a pressure opening 3. To vent of air to pass through the suction port 4 has been sucked in, is at the pressure opening 3
  • Control disc 2 provided a venting device, which in the form of a groove-shaped recess 6 in the control disk 2 is formed.
