Definitions

  • the invention relates to a fuel delivery device for conveying fuel in the direction of an internal combustion engine.
  • DE 100 06 622 describes a fuel supply device for an internal combustion engine of a motor vehicle, wherein a delivery unit promotes fuel from a reservoir to the engine. Downstream of the delivery unit, a fuel filter is arranged and downstream of the fuel filter, a pressure sensor is arranged. The pressure sensor is connected to a control device, by means of which the operation of the delivery unit is controlled such that the fuel pressure is at least approximately equal to a desired pressure.
  • the control device is arranged outside of the delivery unit.
  • DE 199 17 349 describes a pump assembly having a pump head and a pump housing within which an electric pump is disposed. Furthermore, for remote control of the electric pump a provided electronic control device. The control device is located outside the electric pump.
  • control electronics By providing a control electronics outside of the pump housing, a high cost of materials is caused. Furthermore, electrical losses occur due to the long conduction paths from the pump to the control device. Furthermore, a relatively large volume of construction is required because the control electronics claimed a separate housing. Furthermore, contact difficulties can occur at the electrical contact with the fuel pump, which increases the probability of failure of the fuel pump. In particular, an interruption of the contact, caused for example by vibrations.
  • WO 2006/080272 A1 describes a fuel delivery device having a fuel pump, a fuel filter and a filter head connected to the filter housing.
  • the control electronics is arranged on the filter head.
  • the object of the invention is to provide a fuel delivery device that is constructed inexpensively and allows a more reliable operation.
  • a fuel delivery device for delivering fuel toward an internal combustion engine includes a pump housing and a pump head connected to the pump housing. Furthermore, a fuel pump is provided with an electronically commutated brushless motor. The fuel pump is preferably disposed within a fuel filter, which in turn may be housed in the filter housing can. The filter housing can be closed, for example, at its geodetically upper side by the filter head.
  • control electronics for the electronically commutated brushless motor of the fuel pump are arranged in and / or on the pump head.
  • the control electronics can be completely housed in the pump head. Also, the control electronics completely outside, but be mounted directly on the pump head. A combination of these two embodiments is also possible.
  • a pressure sensor for regulating the pressure of the fuel pump is arranged in or on the filter head.
  • the probability of failure of the fuel delivery device can also be reduced, as can be dispensed with an external contacting of the fuel pump to the control electronics.
  • the required construction volume for the fuel delivery device can be further reduced because the control electronics does not require a separate housing.
  • the use of a brushless motor allows for a more robust design that allows for reliable operation of the fuel delivery device. In particular, disturbances in the operation of the fuel pump can be reduced by a brushless motor.
  • the fuel filter is disposed within the pump housing, preferably around the pump, so that the pump housing is a filter housing.
  • the pump head is designed as a filter head.
  • an electronic control system in particular for speed control of the electronically commutated brushless motor of the fuel pump is arranged in and / or on the filter head.
  • All mentioned electronic components can be mounted on a circuit board in and / or on the filter head, for example.
  • the control electronics in the filter head may be, for example, an electronic circuit by which the stator of the electronically commutated motor is driven.
  • the control can take place in dependence on the rotor position, which can be measured with a suitable device, for example by Hall sensors.
  • the filter head comprises a material with high thermal conductivity, for example a metallic material.
  • the material of the filter head has a thermal conductivity of more than 100 W / mK and in particular a thermal conductivity of more than 200 W / mK.
  • Preferred materials are, for example, die-cast zinc with a thermal conductivity of about 115 W / mK or aluminum with a thermal conductivity of about 237 W / mK.
  • the filter head may have a heat sink, for example with cooling fins or an otherwise enlarged cooling surface. If a high thermal conductivity of the filter head is not needed, for example because the components to be cooled produce a low heat loss, a plastic material can also be used. This is preferably PA6.6 (melt), which has a thermal conductivity of about 0.28 W / mK.
  • control electronics with good thermal conductivity to the filter head.
  • the control electronics may be formed, for example, as a circuit board, which has a large contact area to the filter head.
  • a fuel delivery device 11 for conveying fuel in the direction of an internal combustion engine, not shown, has a filter housing 10, a Filter head 12, and a fuel filter 14.
  • a fuel pump 16 with an electronically commutated brushless motor, not shown, is disposed within the fuel filter 14.
  • the filter housing 10 has an inlet 30, is sucked through the fuel by the fuel pump 16. Furthermore, an outlet 32 is provided, is conveyed via the fuel by the fuel pump 16 in the direction of the internal combustion engine.
  • the filter head 12 may for example have a circuit board on which the control electronics 18 is arranged for the electronically commutated brushless motor of the fuel pump. On this board, an electronic pressure sensor 20 for pressure control of the fuel pump 16 is further provided. Alternatively, a mechanical pressure control by a mechanical pressure regulator can take place.
  • the fuel delivery device may have an electrical connection device 26.
  • the filter head 12 may comprise a metallic material.
  • a cooling body 22 may be provided. This may for example be attached to a cover 24 which is connected to the filter head 12.
  • seals for sealing purposes, for example, above and below the fuel pump, seals, in particular in the form of O-rings may be provided. These can be arranged, for example, between the fuel pump 16 and the filter housing 10 or between the fuel filter 14 and the filter housing 10 or the filter head 12.
