Definitions

  • the regulator is of the type which has an rpm-responsive"centrifugal governor including pivotable centrifugal weights and a three-dimensional cam supported coaxiallywith the centrifugal weights and displaceable thereby in anaxial direction/The threedimensional cam is also angularly 'displaceable as a function of the position of a butterfly yalve disposed in the air intake tube of the internal combustion engine.
  • the follower member of a transfer or linkage system is in contact with the three-dimensional cam and is actuated thereby.
  • the transfer system controls, in response to the position of the follower member,-the position of the fuel rack of a fuel injection apparatus.
  • Each centrifugal weight has at least one arm having two work faces. One work face of each arm engages a frontal radial face of the three-dimensional cam, while the other work face of each arm engages an intermediate member which transmits the centrifugal forces to governor springs exerting a resetting force on the threedimensional cam.
  • the axial displacement of the three dimensional cam is, in known governors, equal to the displacement of the intermediate member and thus equal to the shift of the work faces at :the arms of the centrifugal weights.
  • the threedimensional cam is, by means of an operator lever 23, angularly adjustable through a linkage lever 24.
  • an operator lever 23 angularly adjustable through a linkage lever 24.
  • different ranges of theperiphery of the threedimensional cam 15 will be aligned with a follower member 25 of a first intermediate lever 26 which forms part of a force transfer or linkage system and which has the configuration of a bell crank lever.
  • the operator lever 23 is connected with the butterfly valve disposed in the air intake tube 20 (both shown only symbolically) of the internal combustion engine.
  • the increase of the stroke of the three-dimensional cam 15 achieved by the particular disposition of the work faces 38 and 39 at the arm 14 of each centrifugal weight 13 is kept between bounds by the fact that the greatest possible distance of the contact area 41, 41 of the three-dimensional cam 15 from the pivotal axis 43 is limited by the outer diameter of the radial face 42 of the three-dimensional cam 15 when the centrifugal weights 13 are in their outermost position as shown in FIG. 3.
  • a regulator for controlling the air-fuel ratio in a spark plug-ignitedinternal combustion engine operating on injected fuel said engine including an air intake tube and an arbitrarily operable butterfly valve disposed therein, said regulator being of the known type that has (a) rpm-responsive centrifugal weights each swingable about a pivotal axis while revolving about a rotational axis, (b) at least one arm integral with each centrifugal weight, each arm having a first work face and a second work face, (0) a three-dimensional cam supported coaxially with said rotational axis, said threedimensional can being in contact with said first work face to cause an axial displacement of said three dimensional cam by said centrifugal weights, (d) at least one governor spring opposing the axial displacement of said three-dimensional cam in response to rpm increases, (e) an axially shiftable intermediate member supported coaxially with said rotational axis and being urged against said second work face of said arm by said governor spring, (1) means for
