FULL CLOSING ADJUSTING MECHANISM OF CHOKE VALVE FOR BUTTERFLY THROTTLE VALVE TYPE CARBURETOR

摘要

PROBLEM TO BE SOLVED: To adjust a throttle valve so that a choke valve comes in a full closing position to the specified opening of the throttle valve even if production dispersion is present in the choke valve and a throttle valve lever.;SOLUTION: In order to slightly open the throttle valve 10 by linkage with the closing operation of the chock valve 13, a cut 27 is installed in an adjusting bending piece 26 united to a choke valve lever 15, one of leg pieces formed in a fork with the cut 27 is brought into contact with a projection installed in a bending locking piece 28 of an idle lever 23. A claw 25 installed in the idle lever 23 is engaged with an engaging tongue piece 22 of the throttle lever 12. One of the leg pieces of the adjusting bending piece 26 is deformed so that the throttle valve 10 becomes the specified opening in the full closing position of the choke valve 13, and the claw 25 installed in the idle lever 23 is engaged with the engaging tongue piece 22 of the throttle lever 12.;COPYRIGHT: (C)2003,JPO
