Description
- The invention relates to a housing part, in particular a pump housing part, having a functional unit, in particular a metering unit, that is secured releasably, or in other words repeatedly separably without destruction, and in pressure-tight fashion to the housing part.
- Conventional metering units for instance have a flange with through holes for screws with which the flange is secured to the pump housing part. The orientation of the metering unit with the pump housing part is defined by the disposition of the through holes. This can lead to space conflicts when the pump housing part or the associated pump is installed in a motor vehicle. It is also possible to secure a metering unit to a housing part with the aid of a union nut. The union nut requires a relatively large amount of free space, to make access possible for an installation tool.
- The object of the invention is to optimize the securing of a functional unit, in particular a metering unit, to a housing part, in particular a pump housing part.
- In a housing part, in particular a pump housing part, having a functional unit, in particular a metering unit, which is secured releasably, that is, repeatedly nondestructively separably, and in pressure-tight fashion on the housing part, attained in that on the housing part, a collar is provided, which has a tapered collar face on which a first tapered face of at least one tapered element rests, which element has a second tapered face on which a tapered ring face of a tapered ring comes into contact when the tapered ring is moved from an open position to a closed position, in order to press a positive-engagement face of the tapered element against a counterpart face that is provided on the functional unit. The invention creates an easily installed positive- and nonpositive-engagement connection between the functional unit and the housing part. The functional unit can be oriented in arbitrary directions relative to the housing part. No screw bores need to be made in the housing part. For both the connection itself and for installation, only little space is needed.
- A preferred exemplary embodiment of the housing part is characterized in that the collar extends over a circumferential angle of more than 180° and less than 360°, so that the collar is not embodied continuously in the circumferential direction but instead has a mounting opening. The mounting opening enables insertion of the tapered element between the counterpart face and the tapered collar face.
- A further preferred exemplary embodiment of the housing part is characterized in that the collar extends over a circumferential angle of approximately 270°. The mounting opening then extends over a circumferential angle of approximately 90°. This facilitates the insertion of the tapered element or a plurality of tapered elements.
- A further preferred exemplary embodiment of the housing part is characterized in that at least two tapered elements are disposed between the tapered collar face and the counterpart face. As a result, stable securing of the functional unit to the pump housing part is assured.
- A further preferred exemplar embodiment of the housing part is characterized in that the counterpart face is provided on a rim that is embodied on the functional unit. Preferably, the rim extends in the radial direction on the side of the functional unit toward the pump housing part.
- A further preferred exemplary embodiment of the housing part is characterized in that the second tapered face is disposed at an angle of 81 to 89° relative to the positive-engagement face of the tapered element. Preferably, an angle of approximately 85° is enclosed between the second tapered face and the positive-engagement face.
- A further preferred exemplary embodiment of the housing part is characterized in that the second tapered face is disposed at an angle of 40 to 90° relative to the first tapered face of the tapered element. Preferably, an angle of approximately 65° is enclosed between the first and second tapered faces of the tapered element.
- A further preferred exemplary embodiment of the housing part is characterized in that the tapered ring has an annular groove extending in the circumferential direction. The annular groove creates an engagement capability for an installation tool, with which the tapered ring can be loosened as needed in order to dismantle the functional unit.

The ends of three pistons arranged in a star pattern are in contact with the eccentric shaft portion. The ends of the piston facing away from the drive shaft define work chambers, which are also called pump chambers. Each of the work chambers communicates with a low-pressure region via a respective suction valve and with the interposition of a metering unit 4. - The work chambers furthermore communicate via pressure valves with a high-pressure fuel reservoir, also known as a common rail, or simply rail for short. From the common rail, high-pressure lines lead to fuel injection valves. The common rail is in communication with the low-pressure region via a pressure limiting valve. A rail pressure sensor, by way of which the pressure in the common rail is detected, is also attached to the common rail.
- The
pump 1 serves to pump fuel from the low-pressure region into the common rail. Upon intake, the suction valves open, while the pressure valves are conversely closed. Via the metering unit 4, the pumping capacity of the high-pressure pump 1 can be controlled. When fuel is being pumped into the common rail, the suction valves are closed and the pressure valves are open. The metering unit 4 includes ametering unit housing 5, which is shown inFIG. 1 in the preassembled state. - In

Thecollar 14 is not embodied continuously in the circumferential direction but instead is interrupted in a mounting region. Radially inward, the collar has an introduction funnel, which tapers toward theattachment face 7. Atapered collar face 16 begins at the inner end of theintroduction funnel 15 and is inclined downward at an angle of approximately 35° to a horizontal line. Thetapered collar face 16 is disposed at a distance from thecollar 9. - A tapered
element 20 is disposed between thetapered collar face 16 and thecollar 9. The taperedelement 20, viewed in cross section, has a firsttapered face 21, which rests on the taperedcollar face 16 of thepump housing part 2. Radially inward, the taperedelement 20 has a secondtapered face 22, which forms a bearing face for the taperedring face 12 that is embodied radially outward on the taperedring 10. The secondtapered face 22 is disposed at an angle of approximately 65° to the firsttapered face 21. The taperedelement 20 extends over a circumferential angle range of less than 180°.

InFIGS. 1 and 2 , themetering unit 1 is shown in the preassembled, unfastened state. In this state, the metering unit 4 can be rotated relative to thepump housing part 2. In assembly, the metering unit 4 is inserted into the opening, defined by thecollar 14, in thepump housing part 2. Then the tapered elements are thrust through the mounting opening into the groove that is defined by the taperedcollar face 16 and thecounterpart face 25 of therim 9. Next, the metering unit 4 is oriented in such a way that a plug, provided on the metering unit 4, points in the desired direction. Finally, the taperedring 10 is moved downward, as indicated inFIG. 2 by anarrow 28. - In
FIGS. 3 and 4 , the fully assembled state of the metering unit 4 on thepump housing part 2 is shown. InFIG. 4 , it can be seen that the taperedring 10 has been press-fitted into the conically inward-tapering annular chamber between theguide face 8 and the secondtapered face 22 in such a way that the taperedelement 20 has been displaced radially outward. Via the conical tapered faces 21 and 22 on the taperedelement 20, the taperedelement 20 is firmly clamped between the firsttapered face 21 and thecounterpart face 25.
