Claims
- 1. A limit device for a carburetor comprising
- a body,
- a fuel adjustment valve inserted in said body, said adjustment valve including a valve extension extending from said body, said valve extension having a screw head formed on the end thereof, a knurled portion nearly adjacent said screw head, and a lock groove interposed between said screw head and said knurled portion, and
- a generally cylindrical cap mounted on said adjustment valve, said cap including an axial latch adapted to foldably pass over said screw head and close into said lock groove of said valve extension, and a radial lock adapted to engage said knurled portion of said valve extension.
- 2. The limit device of claim 1, wherein said axial latch comprises thin plastic extending angularly and inwardly away from said body.
- 3. The limit device of claim 1, wherein said cap further comprises at least one radially extending appendage adapted to limit rotation of said cap.
- 4. The limit device of claim 1, wherein said cap is received in a retainer.
- 5. The limit device of claim 1, wherein said knurled portion of said valve extension comprises a plurality of coarsely and longitudinally cut knurls.
- 6. The limit device of claim 1, wherein said radial lock of said cap further comprises radial lock grooves longitudinally cut internal to said cap.
- 7. The limit device of claim 1, wherein said screw head is constructed to break away from said valve extension of said adjustment valve at a torque approximately exceeding 8 kg-cm.
- 8. The limit device of claim 1, wherein said axial latch has a plurality of slits cut therein.
- 9. A limit device for a carburetor comprising
- a body,
- a fuel adjustment valve retained in said body and having a valve extension extending away from said body, said valve extension including a screw head formed on the end of said valve extension and a lock groove radially cut into the valve extension nearly adjacent the screw head, said screw head being constructed to break away from said valve extension at about 8 kg-cm torque, and
- a cylindrical cap having an axial latch and a radial lock adapted to engage said valve extension of said adjustment valve.
- 10. The limit device of claim 9, wherein said cap further comprises at least one radially extending appendage adapted to limit rotation of said cap.
- 11. The limit device of claim 9, wherein said cap is received in a retainer.
- 12. The limit device of claim 9, wherein said valve extension further comprises a knurled portion nearly adjacent said lock groove, said knurled portion comprising a plurality of coarsely cut longitudinal knurls.
- 13. The limit device of claim 9, wherein said radial lock of said cap further comprises radial lock grooves longitudinally cut internal to said cap.
- 14. The limit device of claim 9, wherein said axial latch internally extends angularly away from said body in said cap, said axial latch being adapted to foldably pass over said screw head and close into said lock groove of said valve extension of said fuel adjustment valve.
- 15. A limit device for a carburetor comprising
- a body,
- a fuel adjustment valve inserted into said body, said adjustment valve including a valve extension extending away from said body and having a knurled portion,
- a retainer attached to said body and adapted to receive said valve extension, and
- a cap received in said retainer, said cap having an axial lock and a radial lock, said axial lock being external to said cap and adapted to abut a stop in said retainer, said radial lock being adapted to engage said knurled portion of said valve extension.
- 16. The limit device of claim 15, wherein said cap further comprises at least one radially extending appendage adapted to limit rotation of said cap.
- 17. The limit device of claim 15, wherein said knurled portion of said valve extension comprises a plurality of coarsely cut longitudinal knurls.
- 18. The limit device of claim 17, wherein said radial lock of said cap further comprises radial lock grooves longitudinally cut internal to said cap.
- 19. The limit device of claim 15, wherein said screw head is constructed to break away from said valve extension of said adjustment valve at about 8 kg-cm torque.
- 20. A limit device for a carburetor comprising
- a body,
- a fuel adjustment valve inserted in said body, said adjustment valve including a screw head formed on an end external to said body, and
- a cap mounted on said adjustment valve, said cap including a latch adapted to foldably pass over said screw head and axially lock said cap on said adjustment valve.
- 21. The limit device of claim 20 wherein said cap further comprises a radial lock adapted to engage said screw head.
- 22. The limit device of claim 20, wherein said axial latch comprises thin plastic extending angularly and inwardly away from said body.
- 23. The limit device of claim 20, wherein said cap further comprises at least one radially extending appendage adapted to limit rotation of said cap.
- 24. The limit device of claim 20, wherein said cap is received in a retainer.
- 25. The limit device of claim 21, wherein said radial lock of said cap further comprises radial lock grooves longitudinally cut therein.
- 26. The limit device of claim 20, wherein said screw head is constructed to break away from said valve extension of said adjustment valve at a torque approximately exceeding 8 kg-cm.
- 27. A limit cap for a carburetor fuel valve comprising
- a generally cylindrical body, and
- a latch formed internal to said body, said latch being adapted to foldably pass over a screw head of a carburetor fuel valve and axially lock said body on the fuel valve.
- 28. The limit cap of claim 27 further comprising a radial lock formed internal to said body.
- 29. The limit cap of claim 27 wherein said latch is formed of thin plastic.
- 30. The limit cap of claim 27 further comprising a radially extending appendage.
- 31. The limit cap of claim 28, wherein said radial lock further comprises grooves longitudinally cut therein.
