Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
A governor mechanism for an internal combustion engine having a pair of cylinder banks disposed at an angle relative to each other, said cylinder banks being staggered along the length of the output shaft of the engine, a speed responsive element driven by said output shaft contiguous to the adjacent end of said cylinder banks, a throttle valve positioned adjacent the other ends of said cylinder banks for controlling the speed of said engine, and linkage means interconnecting said speed responsive means to said throttle valve for maintaining a desired engine speed, said linkage means including at least one member extending along one side of the cylinder which side is positioned further from a plane defined by the corresponding side of the other cylinder bank so that the member is disposed within the stagger area of the cylinder banks.
