Distributor ignition internal combustion engines, relates to a variable speed drive of the ignition advance is equipped with centrifugal weights

摘要

The distributor is equipped with a centrifugal advance varying device A comprising a first rotary element 12 having pins 16 on which centrifugal weights 18 are articulated; a second rotary element 14 turning together with a toothed rotor 28 and carrying control stubs 22 associated with cams 20 of the said masses 18, so as angularly to offset the said first and second elements 12, 14; and elastic means 30 counterbalancing the centrifugal force applied to the said weights 18. The stubs 22 and the second rotary element 14 form a single component made by sintering. IMAGE
