Abstract
Abstract A fuel regulating system including provision for automatically adjusting the fuel supply as a function of increasing or decreasing engine speed. A movable sleeve member actuable by the action of a centrifugal type governor actuates a control lever which in turn regulates the quantity of fuel delivered to the engine. The control lever is further attached to a manual throttle of the cam type with an intermediate spring plunger to provide for operator adjustment of the fuel. Additionally, there is provided a pair of adjustable stops engageable with the lower end of the control lever to provide respectively low idle speed and high idle speed limits.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
195 words
In a fuel regulating system for an internal combustion engine having a fuel control rod movable axially to increase and decrease fuel flow to the engine, the improvement comprising, a lever pivotally mounted to said rod and operable to move said rod axially upon movement of said lever, said lever being pivotal about an intermediate point and about a lower point whereby pivotting of said lever about either of said pivotal points moves said lever to regulate fuel flow to said engine, means connected with said lever at said intermediate pivotal point to move said intermediate pivotal point linearly parallel with the axis of said fuel control rod in response to changes in the speed of said internal combustion engine, means mounting the lower end of said lever for linear movement parallel to movement of said fuel control rod and including mans urging said lower end to a linear position in which said lever is pivotted about said intermediate pivot point toward a position urging said fuel control rod in a fuel decreasing direction, and means for manually moving said fuel control rod to thereby pivot said lever about said intermediate and lower pivot points.
Claim 2
Dependent Claim
195 words
In a fuel regulating system for an internal combustion engine having a fuel control rod movable axially to increase and decrease fuel flow to the engine, the improvement comprising, a lever pivotally mounted to said rod and operable to move said rod axially upon movement of said lever, said lever being pivotal about an intermediate point and about a lower point whereby pivotting of said lever about either of said pivotal points moves said lever to regulate fuel flow to said engine, means connected with said lever at said intermediate pivotal point to move said intermediate pivotal point linearly parallel with the axis of said fuel control rod in response to changes in the speed of said internal combustion engine, means mounting the lower end of said lever for linear movement parallel to movement of said fuel control rod and including mans urging said lower end to a linear position in which said lever is pivotted about said intermediate pivot point toward a position urging said fuel control rod in a fuel decreasing direction, and means for manually moving said fuel control rod to thereby pivot said lever about said intermediate and lower pivot points.
Claim 3
Dependent Claim
105 words
The fuel regulating system as defined in claim 1 and in which said last mentioned means comprises a cylinder, said fuel control rod having a flange portion at one end disposed within said cylinder, a cam member rotatable between a number of positions and engaging a member carried within said cylinder to urge said member into said cylinder to an extent determined by the lobes of said cam member and a spring disposed between said member and said flange portion to transmit movement of said member through said spring and to said flange to thereby urge said fuel control rod in a fuel regulating direction.
Claim 4
Dependent Claim
55 words
The system as defined in claim 1 and in which said lower mounting means for said lever includes adjustable stop members limiting linear movement of the lower end of said lever one of said adjustable stop members providing low idle speed limit means and the other of said stop members providing high idle speed means.
