Definitions

  • the present invention relates to a pendulum slider pump with an inner rotor, which is connected via pendulum with an outer rotor, according to the preamble of claim 1.
  • a generic pendulum slide pump is known, with which from a voltage applied to the drive shaft torque with an eccentric revolution, the conveying effect of a positive displacement pump can be achieved.
  • a cylindrical working space is arranged, on the lateral surface of which are at least five distributed over the circumference arranged pan grooves, in which the heads are arranged by pendulum webs.
  • pressure ring is rotatably disposed, wherein below the pendulum grooves of the pressure ring in the foot area both the suction kidney and the pressure kidney directed towards flow openings are arranged.
  • a disadvantage of the pendulum slide pumps known from the prior art is that in these a Pendelfelfraum, that is not limited by two groove walls and a groove bottom of the inner rotor and the associated pendulum foot space or difficult filled or emptied.
  • fluid in particular oil, accumulates in the pendulum foot space, whereby a dynamic pressure is built up which changes the eccentricity of the outer rotor relative to the inner rotor or influences it in an uncontrolled manner, thereby making exact control of the delivery rate of the pendulum slide pump more difficult.
  • the present invention therefore addresses the problem of providing an improved or at least one alternative embodiment for a pendulum vane pump of the generic type, in which the disadvantages known from the prior art do not occur.
  • the present invention is based on the general idea to provide a connecting channel between a Pendelfußraum and an associated, outer chamber, which reliably prevents the build-up of a dynamic pressure in the Pendelfelfraum and which is also designed or arranged so that it guides the pendulum in an associated radial groove of an inner rotor of the pendulum slide pump is not adversely affected.
  • the pendulum slide pump according to the invention has in the said inner rotor, which is connected via pendulum with an outer rotor.
  • the pendulums are hinged to the outer rotor and guided at the same time with their pendulum foot in radial grooves in the inner rotor.
  • the outer rotor, the inner rotor and two circumferentially adjacent pendulum limit each case a pressure / suction chamber (pressure / suction kidney) of the pendulum slide pump. Furthermore, the pendulum foot limits together with two groove walls and a groove bottom the previously described Pendelfußraum, which is now connected via the connecting channel with an outer chamber, such as the suction / pressure chamber, and at the same time in the area of the groove bottom opens into the Pendelfußraum.
  • the inventive arrangement of the connecting channel can be a simple filling or emptying of the Pendelfußraumes with liquid, for example, with oil, whereby a hitherto occurring in this area and unwanted dynamic pressure formation can be reliably avoided.
  • the exact controllable eccentricity and the delivery volume of the pendulum slide pump according to the invention is precisely adjustable.
  • the back pressure built up in the pendulum foot space caused the pendulums to be prevented from retracting into the groove due to the incompressibility of the fluid located in the pendulum foot space, whereby the eccentricity of the outer rotor relative to the inner rotor in this groove Angle range was increased.
  • the chamber volume limited by the outer rotor, the inner rotor and two pendulums adjacent in the circumferential direction and thus also the flow rate of the pendulum slide cell pump changes.
  • a motor driving the pendulum-type slide pump must fight against the dynamic pressure, which requires increased drive power.
  • the invention provided in the region of the groove bottom mouth of the Connecting ducts in the pendulum footwell also a preferably complete emptying of the Pendelfußraums can be ensured, so that the pendulum are hindered in their retraction movement in any way.
  • the bottom-side mouth of the connecting channel in the Pendelfelfraum offers the great advantage that the groove walls of the respective pendulum groove leading are otherwise unaffected, creating a low-friction and undisturbed leadership of each pendulum is possible.
  • a connecting channel is provided per pendulum footwell, which is arranged in the direction of rotation before or after the associated pendulum. Due to the different arrangement of the connection channels, the balance of power in the pump can be adapted to the specific application. Thus, in an arrangement in front of the associated pendulum, the tendency to Abregeln, that is, a reduction in the eccentricity of the inner rotor can be reduced. This can achieve an advantageous operating condition, which is characterized by a special stability. Also can be imagined depending on the application, just to allow a lighter Abregein the pump by the connecting channel is arranged after the associated pendulum, for example, to achieve a lighter adjustment of the eccentricity.
  • two connecting channels are provided per Pendelfußraum, which are arranged in the direction of rotation before and after the associated pendulum.
  • the at least one connecting channel is formed as a bore or closed as a groove and in this case by a frontal lid.
  • the formations of the connecting channel as a bore offer the great advantage that the connecting channel can be retrofitted easily and yet extremely accurately in the inner rotor.
  • the connecting channel may also be formed as a frontally arranged on the respective inner rotor groove which communicates via a corresponding connecting portion with the groove bottom of the respective Pendelfußraumes.
  • the groove is formed in the inner rotor and the connecting channel formed by covering this groove by means of a lid.
  • the at least one connecting channel can of course also be produced by primary shaping, in particular by sintering or by a corresponding casting core during casting. In the latter case, the casting core is washed out after casting, thereby leaving behind the connecting channel.
  • Sintering methods are also conceivable for producing the inner rotor or the connecting channel. Eroding methods are basically suitable for the production of the connecting channel.
  • the connecting channel is rectilinear or bent.
  • the straight-line design offers the advantage of being able to produce the connecting channel, for example by means of a simple drilling.
  • a curved connection channel can, for example, constructive Particularities must be taken into account and produced by erosion or casting by inserting a corresponding salt or sand core.
  • An inventive pendulum slide pump 1 which may be formed for example as an oil pump in a motor vehicle, an inner rotor 2, which is connected via pendulum 3 with an outer rotor 4.
  • the pendulum 3 are hinged to the outer rotor 4 and guided with its pendulum foot 5 in radial grooves 6 in the inner rotor 2.
  • the pendulum 3 have a pendulum head, which is mounted in a corresponding socket on the outer rotor 4.
  • the outer rotor 4, the inner rotor 2 and two circumferentially adjacent pendulum 3 also limit a chamber 7, which is formed depending on the rotational position as a suction chamber or as a pressure chamber.
  • each Pendelfußraum 10 is connected via a connecting channel with the associated chamber 7, wherein the connecting channel 11 is arranged depending on the direction of rotation of the inner rotor 2 before or after the associated pendulum 3. If you look at the other hand Fig. 3 , it can be seen from this, that in principle two connecting channels 11 per Pendelfußraum 10 may be provided, which are arranged in the direction of rotation before and after the associated pendulum 3. According to the Fig. 3 is one of the two connecting channels 11 drawn by a solid line and the other with a broken line.
  • connecting channels 11 is a particularly simple and fast filling or mainly emptying of the Pendelfußsammlung 10th possible, whereby an undesirable build-up of dynamic pressure within the Pendelfußraumes 10 can be effectively avoided.
  • the construction of a dynamic pressure is to be avoided precisely because this firstly impedes or prevents a retraction movement of the respective pendulum 3 in the associated groove 6 and thereby affects the eccentricity of the outer rotor 4 relative to the inner rotor 2 undesirable manner. In the case of changed or undesired eccentricity, influence on the delivery behavior of the pendulum vane pump 1 is also taken.
  • the at least one connecting channel 11 at each pendulum foot space 10 the structure of this undesired back pressure can be reliably avoided.
  • the connecting channel 11 may be formed as a groove and closed by a frontal, not shown cover.
  • the connecting channel 11 is formed as a bore, as for example according to the Fig. 3 is shown.
  • the connection channel is made straight.
  • the connecting channel can also be designed bent (see Fig. 1 and 2
  • the connection channel 11 is made, for example, by erosion or casting by the insertion of a corresponding casting core.
  • the at least one connecting channel 11 according to the invention per pendulum foot space 10
  • a directed filling or emptying of the pendulum root cavities 10 is made possible, in particular if only one connecting channel 11 per pendulum foot space 10 is provided.
  • the connecting channel 11 according to the invention also a tendency to wear can be reduced because the pendulum slide pump 1 no longer has to fight against high back pressures within the pendulum footings 10.
  • the mouth of the connecting channel 11 on the bottom side of the respective groove 6, that is in the region of the groove bottom 9 no reduction of the friction surface of the pendulum 3 on the inner rotor 2, that is concretely on the groove walls 8, 8 'on.
