- the Resource line 2 provides one, for example Intake duct 2 of an intake module 3 of the internal combustion engine
- the valve 1 is in a recess 10 of the Installation wall 20 of the equipment line 2 or of the intake module 3 introduced.
- valve 1 in part Sectional view schematically simplified in side view shown valve 1 can be actuated electromagnetically trained and for example part of a no closer shown fuel evaporation retention system Internal combustion engine, its structure and function, for example Bosch technical information, engine management Motronic, second edition, August 1993, pages 48 and 49 is removable.
- the structure and mode of operation of a such, the expert also as a regeneration valve or Tank vent valve known valve 1 is from DE-OS 40 23 044 known, the disclosure of which is also part of the present patent application.
- the valve 1 has a housing 4, which is preferably made of Plastic exists and for example in plastic injection molding technology is made.
- the valve 1 is used to initiate that retained by the evaporative emission control system Fuel into the intake duct 2 of the intake module 3 the internal combustion engine.
- the suction module 3 exists preferably like the housing 4 of the valve 1 from one Plastic that withstands the high strength and can withstand high temperatures of the internal combustion engine.
- a suitable plastic is, for example Polyamide.
- the housing 4 of the valve 1 is stepped cylindrically trained and consists of a first rotating, cross-sectionally smaller outer surface 7 of a first section 8 and a second circumferential, larger cross-section Outer surface 6 of a second section 9 together.
- the Valve 1 is in the corresponding to the outer surfaces 6, 7 of the Valve 1 graduated recess 10 in Intake module 3 at least partially into recess 10 introduced, which along a longitudinal axis 5 from a cross-sectionally larger part 14 with a cross-sectionally larger Inner surface 11 and a part 15 with a smaller cross section an inner surface 12 of smaller cross-section. Between the two parts 14, 15, a paragraph 16 formed, which has an annular surface 17.
- Both parts 14, 15 run centrally to the longitudinal axis 5 and have one cylindrical cross section, which is slightly larger than that in the parts 14, 15 received by the outer surfaces 6, 7 limited, respective cylindrical cross section of the sections 8 or 9 of the valve 1, so that in the built State of the valve 1 between the outer surfaces 6, 7 and Inner surfaces 11, 12 result in two radial gaps 48, 49.
- the inner surface 12 with a smaller cross section goes into a channel 18 over, which opens into the intake duct 2, through the the internal combustion engine air from the environment subsequent suction mixture formation.
- Fuel to the valve 1 takes place, for example via an additional line 13, for example in the form a hose line is formed and on one on one upper housing part 21 of the valve 1 provided inlet connection 22 is attached.
- the fuel preferably downstream one in the intake duct 2 of the Intake module 3 rotatably accommodated throttle valve from the Channel 18 discharged into intake duct 2.
- the valve 1 controls a passage cross section inside Example using a cooperating with a valve seat Closing body. In the passage cross-section flows as Medium for example vapor fuel and air over the additional line 13 in the valve 1 to this fuel-air mixture then, for example, in a clocked manner from the To discharge spigot 23 in the channel 18.
- sealing rings 25, 26 are used in addition to the Sealing of the valve 1 in the recess 10 according to the invention also for storage and fastening of the valve 1 in the Recess 10. Both sealing rings 25, 26 consist of this an elastic material, preferably rubber.
- the Sealing rings 25, 26 are, for example, in the form of so-called O-rings formed a circular cross section exhibit. As shown in Figure 1, the first is Sealing ring 25 in a recessed from the outer surface 7 first annular groove 30 of the first section 8 of the housing 4 brought in.
- the second sealing ring 26 is in the same way into a second recessed from the second outer surface 6 Annular groove 31 of the second section 9 of the housing 4 brought in. Both sealing rings 25, 26 project radially beyond their respective outer surfaces 6, 7 and are at Inserting the valve 1 into the recess 10 elastically deformed, leading the valve 1 radially, however between the inner surfaces 11, 12 of the recess 10 and the Outer surfaces 6, 7 of valve 1 have radial gaps 48, 49 remain.
- the larger cross-sectional inner surface 11 of the recess 10 is partially from an end face 35 of the Intake module 3 protruding, sleeve-shaped extension 36 educated.
- FIG. 2 a top view of FIG. 1, is shown, the sleeve-shaped extension 36 exposes itself several ring snap elements 40 together.
- the one Snap device for holding the valve 1 forming Ring snap elements 40 are circumferential in the direction recesses 41 running parallel to the longitudinal axis 5 separated from each other, so that for example twelve tongue-like ring snap elements 40 are present that are evenly distributed over the circumference of the extension 36.
- the individual ring snap elements 40 are bendable for example made of plastic and can be inserted of valve 1 from housing 4 of valve 1 accordingly bend away.
- the sleeve-shaped extension 36 with the ring snap elements 40 is, for example, like the intake module 3 made of plastic and is used in the manufacture of the intake module 3 for example injection molded in plastic injection molding technology.
- the axial distances of the second sealing ring 26 or the second Annular groove 31 and the groove-shaped recess 45 in the Inner surface 31 of the ring surface 17 are selected in such a way that between the annular surface 17 and one between the cross-sectionally larger outer surface 6 and the cross-sectionally smaller Outer surface 7 remaining valve ring surface 19 there is an axial gap 47.
- the axial gap 47 and the radial gaps 48, 49 close a contact of the Valve 1 on surfaces 11, 12 and 17 in the recess 10.
- the first sealing ring 25 with a smaller cross section lies only radially sealing on the inner surface 12 in a smaller cross-section Part 15 of the recess 10 and is therefore in its axial displacement in the direction of the longitudinal axis 5 not hindered, so that there is almost a floating bearing for the Valve 1 is formed.
- a U-shape can be used, for example, to dismantle the valve 1 wedge between the ring snap elements 40 and the outer surface 6 are inserted into the gap 48.
- the Wedge bends the ring snap elements when inserted into the gap 48 40 something so that the snap connection between the second sealing ring 26 and the ring snap elements 40 is released and the valve 1 is removed from the recess 10 can be.
