Claims
- 1. An air supply system for a vehicle engine comprising:a throttle body including a flow passage for communicating with an air resonator body, and for communicating with a vehicle engine; and an air resonator attached to said throttle body and communicating with said passage, one of said throttle body and said air resonator having a boss extending downwardly into an opening in the other, and a resilient seal positioned between said boss and an inner periphery of said other of said throttle body and said air resonator, said resilient seal providing an interference fit for securing said air resonator to said throttle body, said interference fit being sufficient to solidly retain said air resonator on said throttle body.
- 2. A system as set forth in claim 1, wherein said boss extends downwardly from said throttle body.
- 3. A system as set forth in claim 2, wherein a circumferential groove is formed into an outer periphery of said boss and said seal is positioned in said groove.
- 4. An air supply system for a vehicle engine comprising:a throttle body including a flow passage for communicating with an air resonator body, and for communicating with a vehicle engine; an air resonator attached to said throttle body and communicating with said passage, one of said throttle body and said air resonator having a boss extending downwardly into an opening in the other, and a resilient seal positioned between said boss and an inner periphery of said other of said throttle body and said air resonator, said resilient seal providing an interference fit for securing said air resonator to said throttle body; said boss extending downwardly from said throttle body; a circumferential groove formed into an outer periphery of said boss and said seal positioned in said groove; and said seal has a seal lip extending in a direction away from said air resonator such that a vacuum drawn within said air resonator tends to force said seal further into contact with said bore.
- 5. A system as set forth in claim 4, wherein a vibration isolator is positioned axially inward from said seal lip.
- 6. A system as set forth in claim 5, wherein said seal lip extends at an angle radially outwardly and axially away from said air resonator.
- 7. A system as set forth in claim 5, wherein said vibration isolator includes a pair of vibration isolator lips with a central valley between the two.
- 8. A system as set forth in claim 7, wherein said seal lip extends radially outwardly for a greater extent than said vibration isolators.
- 9. A system as set forth in claim 1, wherein said throttle body is an ETC valve body.
- 10. A system for connecting an electronic throttle control body to an air resonator comprising:an electronic throttle body including a throttle valve positioned in a passage, said passage communicating between an air resonator and an engine, an air resonator assembly connected to communicate with said passage, and a connection between said air resonator system and said ETC body including a seal position between a boss and an inner peripheral bore, said boss being formed on one of said ETC body and said air resonator and said bore being formed on the other, said resilient seal having a free dimension which is of a radially greater dimension than an inner periphery of said bore, such that said air resonator is interference fit on said valve body, said interference fit being sufficient to solidly retain said air resonator on said throttle body.
- 11. A system as set forth in claim 10, wherein said boss extends from said ETC body.
- 12. A system as set forth in claim 11, wherein a circumferential groove is formed into an outer periphery of said boss and said seal is positioned in said groove.
- 13. A system for connecting an electronic throttle control body to an air resonator comprising:an electronic throttle body including a throttle valve positioned in a passage, said passage communicating between an air resonator and an engine, an air resonator assembly connected to communicate with said passage, and a connection between said air resonator system and said ETC body including a seal position between a boss and an inner peripheral bore, said boss being formed on one of said ETC body and said air resonator and said bore being formed on the other, said resilient seal having a free dimension which is of a radially greater dimension than an inner periphery of said bore, such that said air resonator is interference fit on said valve body; said boss extending from said ETC body; a circumferential groove formed into an outer periphery of said boss and said seal positioned in said groove; said seal has a seal lip extending in a direction away from said air resonator such that a vacuum drawn within said air resonator tends to force said seal further into contact with said bore.
- 14. A system as set forth in claim 13, wherein a vibration isolator is positioned axially inward from said seal lip.
- 15. A system as set forth in claim 14, wherein said seal lip extends at an angle radially outwardly and axially away from said air resonator.
- 16. A system as set forth in claim 14, wherein said vibration isolator includes a pair of vibration isolator lips with a central valley between the two.
- 17. A system as set forth in claim 16, wherein said seal lip extends radially outwardly for a greater extent than said vibration isolators.
