Definitions
- a corresponding number of injection throttle bodies are pressed into the cavity of the high-rack storage space body from an open side until the individual injection throttle bodies which contain a throttle opening are positioned in that the throttle openings in the press-fit throttle bodies face the radially extending connection bores for the high-pressure feed lines to the fuel injectors.
- FIG 4.1 the hyperboloid Einpressdrosselelement according to the illustration in Figure 4 in an enlarged view.
- FIG. 2.1 shows the throttle body designed as a deep-drawn component according to the illustration in FIG. 2 on an enlarged scale.
- the deep-drawn throttle body 52 has a substantially pot-shaped appearance and is designed in a small wall thickness 54 suitable for the thermoforming process.
- the throttle channel 34 In the bottom of the substantially cup-shaped, deep-drawn throttle body 52 is the throttle channel 34, which is designed according to this embodiment as a simple through hole.
- the throttle channel 34 opposite side of the deep-drawn throttle body 52 is provided with a diameter extension.
- the cylindrical throttle body 58 can be in the axial direction of insertion Insert 66 of an open end of the high-pressure accumulator 10 in this and then rotate in their corresponding radial position below the individual connection holes 30 so that the dome-shaped elevation 76 in the circumferential surface 64 of the cylinder-shaped throttle body 58 engages in the connection bore 30 and the cylinder-shaped throttle body 58th thus locked within the cavity 68 of the high-pressure storage space 10.
- the throttle body 80 which is in the form of a hyperboloid, has a substantially double conical shape.
- the throttle body 80 embodied as a hyperboloid comprises a constriction 82, which limits the flow cross section of the throttle passage 34 (see reference numeral 96 throttle cross section).
- the throttle body 80 designed as a hyperboloid comprises a first opening 92, which is opposite the high-pressure line 18, and a second opening 94, which opens into the cavity 68 of the high-pressure reservoir 10 as shown in FIG.
- the outer lateral surface in the region of the first opening 92 forms the support ge specifications 56, with which formed as a hyperboloid throttle body 80 is supported on the formation 36 in the wall 12 of the high-pressure accumulator chamber 10.
