Definitions

  • the invention relates to a rotary piston engine according to the preamble of the main claim.
  • a rotary engine is known by the US-A 3,236,186 (Wildhaber, Ernest ) of February 22, 1966.
  • Fig. 4 a rotary piston machine known as a conveyor unit, with at an axial angle to each other arranged rotors (drive part and driven part) and with a machine housing.
  • the working spaces are formed, which are increased or reduced during the rotation of the parts for their work or to produce the conveying effect on a medium.
  • Another such rotary engine is known by the DE-PS 4241320 (Arnold, Felix ) as a pump, compressor or motor, in which run the combs of teeth of a rotating drive part to limit work spaces on a cycloid surface of a likewise toothed driven part and thereby driving it.
  • the rotary piston engine according to the invention with the characterizing features of claim 1 has the advantage that the invention in particular in the fuel delivery of internal combustion engines, for example as a feed pump in diesel injection systems or as pre-feed pump or as a pressure and supply pump of gasoline injection systems, can serve.
  • the combination as a unit, between the motor housing and the machine housing, offers the possibility to make such a delivery or pressure pump small, since the electric motor can attack the output side directly to the drive part of the rotors, without additional complex storage.
  • connection of the housing can be given in various ways, for example, as a screw connection between two "pots" on the one hand surround the pump and on the other hand the electric motor, or there may be a Verbörtelung between a cover part and a cup part, depending on how this for the practical use and, above all, a favorable production makes sense.
  • Decisive for the invention is that in the motor housing, which are arranged part related to the electric motor, such as the magnets and the bearing of the rotor and that the pump housing are housed in the machine housing, including the inflow and outflow device for the medium.
  • Such an "electric pump” according to the invention is not limited in its application as a fuel pump, but can be used depending on the size and performance of liquid or gaseous media, with much higher pressures can be generated than in the known fuel pump (company Robert Bosch GmbH or the like). ,
  • the bearing bush is connected to a bottom bearing for the driven part, on which the driven part is supported on its side facing away from the drive part.
  • bearing bush and bottom bearing on the same axis, perpendicular to the bearing surface stands, on which the output part is supported.
  • the rotors run in an inner housing in which open to the rotors towards the suction channel and the pressure channel are arranged.
  • This inner housing is rotatably and not floating within the rest of the machine housing and in particular against rotation of the bottom bearing.
  • the inner housing may be arranged in an additional housing bushing and secured there against turning.
  • This housing socket in turn, can be stored in the outer machine housing.
  • the rotors run in a recess (of the inner housing), which is open and cylindrical to the driven side, and closed to the drive side and formed spherically.
  • the drive part can be supported, while the driven part is held on the cylindrical side by the bearing bush and the bottom bearing in its working position.
  • the drive part has an inner spherical region on which the drive part with a correspondingly shaped end face, or the bearing bush of the driven part can be supported.
  • the driven part is axially loaded in the direction of the drive part.
  • the output member is loaded by a spring force in the direction of the drive part.
  • a spring force may be particularly advantageous in the starting phase of such a pump in order to achieve the required for the promotion of tightness between the working edges of the intermeshing teeth.
  • the pressure channel of the machine is connected to a space between the driven part and the housing (bottom bearing) on the side facing away from the drive part. This ensures that when the medium has reached a certain pressure in the pressure channel, the driven part is pressed against the drive member so that thereby a better tightness between the flanks can be achieved.
  • the rotor is mounted with its one shaft in a fixed bearing, which is supported by the inner housing and on which the drive member is axially supportable. It is thus a both as a radial bearing for the engine as a thrust bearing for the drive part, the latter particularly causes a reduction in the friction losses between the drive part and the inner housing.
  • the transitions between the mutually facing the axial support serving spherical bearing surfaces and the work space delimiting tooth surfaces are rounded at the rotors.
  • the radius of such rounding preferably has at least 1 mm. Basically, this radius depends on the size of the pump parts.
  • short-circuit channels or short-circuiting grooves are arranged in the bottom surface of the rotors, via which adjacent work spaces can be connected to one another during rotation and, in particular, before opening a suction or pressure channel, in order to accommodate the changing volumes of the work spaces To achieve pressure equalization.
  • the delivery chambers change between the parts, with the associated flanks of the teeth of one part to slide over the corresponding surfaces of the other part, so that the lying between the teeth spaces from which the actual working spaces arise, here act as harmful spaces. While an overpressure would be created in the one harmful room, a negative pressure would be created in the adjacent room.
  • the fuel delivery pump shown has a rotary lobe pump 1 and an electric motor 2 driving this, which are arranged in a motor housing 3 and a housing cover 4 screwed onto it.
  • the electric motor is greatly simplified represents with a rotor 5 and a magnet ring 6, and an axial closure part 7 of the motor housing 3, which is connected to the motor housing 3 and sealed to this.
  • a pivot bearing 8 of the rotor 5, and the pressure port. 9 arranged for the fuel discharge.
  • the fuel pump is designed as a submersible pump, in which via suction ports 10, which are only indicated here, the fuel passes into the pump to then leave the pump via the pressure port 9 again.
  • the electric motor 5, 6 flows around the fuel within the motor housing 3.
  • the second pivot bearing of the rotor 5 is formed as a fixed bearing 11, which is arranged in a corresponding bore on the end face of an inner housing 12 of the rotary lobe pump 1 and on which the drive member 17 can be supported axially.
  • This inner housing 12 is arranged outside in a housing bushing 13, which in turn is sealed to the motor housing 3, partially clamped in this and partially within the housing cover 4.
  • a recess 14 is provided in the inner housing 12, with a cylindrical portion 15 and a spherical portion sixteenth
  • the recess 14 is closed on the output side by a bottom bearing 22, which is arranged obliquely to the axis of the recess 14 in order to achieve the required conveying angle and which is sealed at 23 to the inner housing 12.
  • a bearing pin 24 is arranged perpendicular to the recess 14 facing the end face of the bottom bearing 22, on which via a blind bore 25 (FIG. FIG. 3 ) the driven part 18 is mounted.
  • the output member 18 is also loaded in the direction of the drive member 17 by a coil spring 26 and a ball 27, wherein the spring is arranged in a blind bore 28 of the journal 24 and the ball is supported on the end face of the blind bore 25.
  • the output part 18 is supported via a spherical surface 29 facing the drive part 17 on a corresponding spherical recess 30 on the drive part 17 (FIG. Fig. 3 ).
  • FIGS. 4, 5 and 6 is recognizable as the conveying process takes place.
  • the work spaces 21 ( FIG. 2 ) are supplied with fuel via conveyor kidneys 31 which are arranged in the walls of the inner housing 12, and disposed of.
  • the fuel is then directed to the underside of the driven part 18, whereby this is loaded in the direction of the drive part 17, which, however, only works when the pump has already generated pressure.
