- the valve 1 has a housing 4, which is preferably made of plastic and is manufactured, for example, using plastic injection molding technology.
- the valve 1 serves to introduce the fuel retained by the fuel evaporation retention system into the intake duct 2 of the intake module 3 of the internal combustion engine.
- the suction module 3, like the housing 4 of the valve 1, is preferably made of a plastic that can withstand the high strength and high temperatures of the internal combustion engine.
- a suitable plastic for this is, for example, polyamide.
- the housing 4 of the valve 1 is formed cylindrically stepped and is composed of a first circumferential, cross-sectionally smaller outer surface 7 of a first section 8 and a second circumferential, cross-sectionally larger outer surface 6 of a second section 9.

- the inner surface 12 with a smaller cross section merges into a channel 18, which opens into the intake channel 2, through which the internal combustion engine can suck in air from the environment for the subsequent mixture formation.
- the fuel temporarily stored by the fuel evaporation retention system is supplied to valve 1, for example, via an additional line 13, which is designed, for example, in the form of a hose line and is attached to an inflow connector 22 provided on an upper housing part 21 of valve 1 .
- the fuel is preferably discharged downstream of a throttle valve 23 of the valve 1, which corresponds to the first section 8, opposite the inflow nozzle 22, downstream of a throttle valve rotatably accommodated in the intake duct 2 of the intake module 3 from the duct 18 into the intake duct 2.
- the valve 1 controls a passage cross section in its interior, for example by means of a closing body cooperating with a valve seat. In the passage cross section, for example, vaporous fuel and air flows as a medium via the additional line 13 into the valve 1 in order to Air mixture thereafter, for example, in a clocked manner from the outlet 23 in the channel 18.
- Sealing ring 25 and a cross-sectionally larger second sealing ring 26 are provided.
- the sealing rings 25, 26 also serve to mount and fasten the valve 1 in the recess 10.
- Both sealing rings 25, 26 are made of an elastic material, preferably rubber, for this purpose.
- the sealing rings 25, 26 are, for example, in the form of so-called O-rings which have a circular cross section.
- the first sealing ring 25 is introduced into a first annular groove 30 in the first section 8 of the housing 4, which is recessed from the outer surface 7.
- the second sealing ring 26 is introduced into a second annular groove 31 of the second section 9 of the housing 4, which is recessed from the second outer surface 6.
- Both sealing rings 25, 26 project radially beyond their respective outer surfaces 6, 7 and are elastically deformed when the valve 1 is inserted into the recess 10, guiding the valve 1 radially, but between the inner surfaces 11, 12 of the recess 10 and the outer surfaces 6, 7 of the valve 1, the radial gaps 48, 49 remain.
- the cross-sectionally larger inner surface 11 of the recess 10 is partially formed by a sleeve-shaped extension 36 projecting beyond an end surface 35 of the suction module 3.

- the ring-snap elements 40 forming a snap device for holding the valve 1 are circumferentially through in the direction the longitudinal axis 5 parallel recesses 41 are separated from each other, so that, for example, twelve tongue-like ring snap elements 40 are present, which are evenly distributed on the circumference of the extension 36.
- the individual ring snap elements 40 are bendable, for example made of plastic, and can accordingly bend away from the housing 4 of the valve 1 when the valve 1 is inserted.
- the sleeve-shaped extension 36 with the ring snap elements 40 is made, for example, like the suction module 3 from plastic and is also molded on during the manufacture of the suction module 3, for example in plastic injection molding technology.

- Inner surfaces 11, 12 can take place in the recess 10, an elastic mounting is created, which prevents vibrations emanating from the valve 1 from being transmitted to the intake module 3. This creates an acoustic decoupling of the valve 1 in the recess 10, which greatly reduces the transmission of the operating noise of the valve 1.
- the elastically deformed sealing rings 25, 26 ensure that the valve 1 is sufficiently mechanically held in the recess 10.
- a wedge having a U shape can be inserted into the gap 48 between the ring snap elements 40 and the outer surface 6.
- the wedge bends the ring snap elements 40 slightly when inserted into the gap 48, so that the snap connection between the second sealing ring 26 and the ring snap elements 40 is released and the valve 1 can be removed from the recess 10.
- the ring snap elements 40 can be made in one piece on the suction module 3 Paragraph 36 are formed and molded in a simple manner during the manufacture of the intake module 3, for example in plastic injection molding technology.

- the valve 1 is shown in perspective, which is introduced into a separate component designed as a built-in pot 50 for attachment or mounting.
- the mounting pot 50 has the ring snap elements 40 on its circumference over part of its axial extent and forms the recess 10 for the valve 1.
- the mounting pot 50 which is preferably made of plastic, has a circumferential ring edge 54 with the ring snap elements 40 and a pot base 55 and possibly a connecting piece 56 adjoining the pot base 55 and is provided, for example, for intake modules 3 made of metal for fastening the valve 1 to the intake module 3.
- the built-in pot 50 is, for example, introduced into a cylindrical recess 52 in the metal suction module 3, which is formed according to the outer shape of the built-in pot 50 and is indicated by dashed lines in FIG. 3, and is fastened therein, for example by means of adhesive.
- the valve 1 can then be inserted into the mounting pot 50 and held on the mounting pot 50 by means of the ring snap elements 40. It is of course also possible to insert the installation pot 50 into a cylindrical recess in an intake module 3 made of plastic, in order to fasten the valve 1 to the intake module 3.
- the unit can also be a Act injection valve of known type, as is known for example from US-PS 5,156,133 or from GB-PS 1 603 501.
- the invention can also be readily transferred to so-called exhaust gas recirculation valves, as are known, for example, from WO 95/27134.
- the invention is also suitable for other valves, for example valves for idle control of the internal combustion engine, as are known, for example, from US Pat. No. 5,497,746.
- a transfer to so-called changeover or directional control valves is also possible in internal combustion engines equipped with an intake manifold supercharger, as are known, for example, from DE-OS 41 05 938.
