Governor assist mechanism

An apparatus for affecting the speed of an engine having an intake manifold, comprising:

• (a) a primary governor device having a control arm and a primary governor arm, said control arm having two ends, a first end interconnected to a throttle device and a second end which is directly connected to said primary governor arm at one of several attachment points, said primary governor arm including a pivot point and including a primary governor spring which is attached to said primary governor arm at one of several attachment points;
• (b) an assist spring having a first end directly interconnected to the primary governor arm at one of several attachment points, said assist spring having an opposite second end, wherein movement of said assist spring adjusts the position of said primary governor arm and said control arm;
• (c) vacuum actuating means operatively interconnected to said second end of said assist spring, including:
• (i) a vacuum capsule having a first and second chamber, said first chamber being at atmospheric pressure and said second chamber being in fluid communication with the intake manifold via a conduit so as to have the same pressure as the intake manifold, said first and second chambers being divided by a movable diaphragm;
• and
• (ii) a diaphragm plunger interconnected to said diaphragm, one end of said diaphragm plunger being directly interconnected to said assist spring so as to control movement thereof, said assist spring being external to said vacuum capsule,
• wherein said diaphragm moves automatically in response to the pressure in the intake manifold.
