Abstract
A device for a fuel delivery module is known, which has a controller housing in which a carrier with control electronics for controlling a fuel delivery pump is arranged, and a pressure sensor for measuring the pressure in the fuel tank, i.e. outside the housing. A disadvantage is that the pressure sensor requires separate wiring, which for example comprises the voltage supply lines and the signal lines for the pressure sensor and is arranged relatively complicated in production. In the arrangement shown, separate wiring for the pressure sensor is omitted or at least shortened, so that the production costs are reduced. Provision is made for the pressure sensor (6) to be arranged in the controller housing (2) and to be electrically connected to the control electronics (4).
Description
Technical Field
The invention is based on a device for a fuel delivery module according to the generic type of the independent claim.
Background
A device for a fuel delivery module is known from EP 1031725 a2, which has a controller housing in which a carrier with control electronics for controlling a fuel delivery pump is arranged, and a pressure sensor for measuring the pressure in the fuel tank, i.e. outside the controller housing. A disadvantage is that the pressure sensor requires separate wiring, which for example comprises the voltage supply and the signal lines for the pressure sensor and which is relatively complex to produce.
Disclosure of Invention
In contrast, the device according to the invention having the features of the characterizing portion of the independent claim has the following advantages: the separate wiring for the pressure sensor is eliminated or at least shortened, so that the manufacturing costs are reduced. This is achieved according to the invention by: a pressure sensor is arranged in the controller housing and is electrically connected to the control electronics and is provided with a pressure connection opening into the controller housing for measuring the pressure outside the controller housing.
Advantageous embodiments and refinements of the device specified in the independent claims can be achieved by the measures cited in the dependent claims.
It is particularly advantageous if the pressure sensor has a sensor housing, a measurement chamber formed in the sensor housing and a pressure measurement opening which leads from outside the sensor housing into the measurement chamber, the measurement chamber having a pressure sensor element arranged therein. In this way, the pressure is conducted from outside the controller housing, i.e. for example from the fuel tank, into the measuring chamber of the sensor housing and can be measured there.
Furthermore, it is advantageous if the pressure sensor is arranged in the control unit housing in such a way that the pressure connection opening of the control unit housing opens directly into the pressure measurement opening of the sensor housing or via a hose connection or a tube connection. In this way, the pressure in the fuel tank can be measured particularly accurately.
According to one advantageous embodiment, the connection between the pressure connection opening of the controller housing and the pressure measurement opening of the sensor housing is sealed by a sealing ring. In this way, fuel vapors from the fuel tank cannot or can only reach a small amount into the part of the interior chamber of the controller housing in which the control electronics are arranged. Thereby, the control electronics are protected from damage due to fuel vapor. Furthermore, the fuel vapors can therefore not be passed to the atmosphere or can only be passed to the atmosphere in small amounts via the control device housing.
It is very advantageous if the control housing has a pressure compensation opening to the atmosphere, since this enables the use of a differential pressure sensor instead of an absolute pressure sensor. Due to the pressure compensation opening, the pressure in the part of the inner chamber of the controller housing containing the control electronics is temperature-independent, so that a differential pressure measurement between the pressure measurement opening and the part of the inner chamber of the controller housing containing the control electronics can be achieved.
It is also advantageous if the carrier of the control electronics is a circuit board on which the electronic components of the control electronics and the conductor tracks are arranged, and if the pressure sensor has sensor connections which are electrically connected to the connection contacts of the circuit board in each case via electrical connection means, in particular contact springs. The pressure sensor is thus connected to the voltage source in a simple manner. Furthermore, the connection contacts are designed in such a way that the pressure signals of the pressure sensor can also be transmitted.
It is also advantageous if the control unit housing has a first connection for connecting the control electronics to the on-board electrical system or to a voltage source, and a second connection for connecting the control electronics to the fuel delivery pump. In this way, the control electronics can control the fuel delivery pump.
It is also advantageous if the control housing is closed by a housing cover, which is produced in particular from plastic or aluminum and in particular has cooling ribs. In this way, the heat of the control electronics can be dissipated via the housing cover.
It is also advantageous if the control housing is formed on a tank flange, in particular of the fuel delivery module, since the control housing can be integrated in the tank flange in a particularly space-saving and compact manner.
It is further advantageous if the tank flange has an underside on which the fuel feed pump is held and a pressure connection opening of the control housing is arranged for measuring the pressure in the fuel tank. In this way, the pressure in the fuel tank can be measured in a simple manner by means of a pressure sensor integrated in the tank flange.
Drawings
Embodiments of the invention are briefly illustrated in the drawings and are explained in detail in the following description.
Fig. 1 shows a cross section of an arrangement according to the invention for a fuel delivery module.
Detailed Description
The device 1 according to the invention comprises a controller housing 2 in which a carrier 3 with control electronics 4 for controlling a fuel delivery pump 5 is arranged, and a pressure sensor 6 for measuring the pressure outside the controller housing 2. The carrier 3 of the control electronics 4 can be, for example, a printed circuit board on which the electronic components 7 and the conductor tracks 8 of the control electronics 4 are arranged.
According to the invention, a pressure sensor 6 is arranged in the control unit housing 2 and is electrically connected to the control electronics 4, and a pressure connection opening 12 is provided in the control unit housing 2 for measuring the pressure outside the control unit housing 2. In this way, the pressure sensor 6 is electrically attached to the control electronics 4 in a simple manner, in particular without complicated wiring to the outside of the controller housing 2, and the pressure outside the controller housing 2 can be measured from within the controller housing 2.
The pressure sensor 6 has a sensor housing 13, a measurement chamber 14 formed in the sensor housing 13, in which a pressure sensor element 15 is arranged, and a pressure measurement opening 17 which leads from outside the sensor housing 13 into the measurement chamber 14. According to this exemplary embodiment, the pressure sensor 6 is arranged in the control unit housing 2 in such a way that the pressure connection opening 12 of the control unit housing 2 opens directly into the pressure measurement opening 17 of the sensor housing 13. For example, the pressure measuring opening 17 of the sensor housing 13 is directly connected to the pressure connection opening 12 of the controller housing 2, wherein the two openings 17, 12 are aligned or arranged concentrically with respect to one another. Alternatively, the pressure connection opening 12 of the controller housing 2 is connected via a hose or pipe connection into the pressure measurement opening 17 of the sensor housing 13. The connection between the pressure connection opening 12 of the controller housing 2 and the pressure measurement opening 17 of the sensor housing 13 can be sealed by a sealing means 18, for example a sealing ring. According to this embodiment, the pressure sensor 6 is fixed on the inner wall 21 of the controller housing 2, for example clamped by means of a snap connection. The pressure sensor 6 is fastened, for example, to an inner wall 21 of the control housing 2, on the outside of which the pressure to be measured acts. Alternatively, the pressure sensor 6 can be fixed, for example riveted or welded, on the carrier 3 of the control electronics 4 and be connected in a flow-through manner to the pressure connection opening 12 of the controller housing 2 via the hose or tube connection.
The pressure sensor 6 can be an absolute pressure sensor or a relative pressure sensor or a differential pressure sensor, wherein, in the case of a relative pressure sensor, a pressure compensation opening 22 to the atmosphere in the control housing 2 is expedient, so that the reference pressure in the interior 16 of the control housing 2 is independent of the temperature in the control housing 2.
In order to attach the pressure sensor 6 electrically and signally to the control electronics 4, the pressure sensor 6 has a sensor connection 23 which is electrically connected to a connection contact 25 of the carrier 3 or of the control electronics 4, respectively, by an electrical connection device 24, for example an electrically conductive contact spring. The contact springs 24 are, for example, elastically pretensioned between the sensor contacts 23 of the pressure sensor 6 and the carrier 3 in order to achieve a reliable electrical connection.
The control unit housing 2 has a first connection 28 for connecting the control electronics 4 to a voltage source or an on-board circuit of the vehicle and additionally to a vehicle control unit, and a second connection 29 for connecting the control electronics 4 to the fuel delivery pump 5.
The control housing 2 is closed by a housing cover 30, which is produced, for example, from plastic or metal, in particular steel or aluminum, and in particular has cooling ribs 32. In order to thermally attach the carrier 3 or the electronic component 4 to the housing cover 30, the carrier 3 can be connected to the housing cover 30 via a heat conducting means 31, for example a heat conducting layer.
According to this embodiment, the controller housing 2 according to the invention is constructed on a tank flange 35 of a fuel delivery module 36. The fuel delivery module 36 comprises at least one tank flange 35 and a fuel delivery pump 5 fixed to the tank flange 35. According to this exemplary embodiment, the fuel feed pump 5 is arranged in a storage tank 37, which is fastened to the tank flange 35 by means of a rod-shaped retaining means 38. The fuel delivery module 36 is provided for arrangement in a fuel tank 40 and for sucking fuel from the fuel tank 40 by means of a fuel delivery pump 5 and delivering it to an internal combustion engine 42 via a pressure line 41 in a known manner. The tank flange 35 closes the tank opening 43 of the fuel tank 40. The tank flange 35, which is integrated with the control device housing 2 according to the invention, has a lower side facing the fuel tank 40, on which lower side the pressure connection opening 12 of the control device housing 2 is arranged for measuring the pressure in the fuel tank 40 and on which lower side at least the fuel feed pump 5 is held. The upper side of the tank flange 35 facing away from the fuel tank 40 is arranged outside the fuel tank 40. The carrier 3 of the control electronics 4 is arranged above the pressure sensor 6, viewed in the direction of gravity, and faces the housing cover 30.
