I claim:
1. The combination with an internal combustion engine having an intake passageway provided with a throttle valve for controlling the 4flow of motive fluid to the engine, means actuated through changes of pressure in the intake passageway on the engine side of said valve for 1mparting movement to said valve, a conduit connecting said pressure actuated means with the intake passageway on the engine side of said throttle valve, and valve means responsive to changes in engine speed for controlling fluid flow through said conduit, said valve means tending to open said conduit whenlthe engine reaches its governed speed and tending to close said conduit when the engine falls below its governed speed.
2. The .combination with an internal combussaid conduit when the engine reaches its governed speed and tending to close said conduit when the engine falls below its governed speed.
3. The combination as set forth in claim 2 including an orice in the intake passageway on the atmosphere side of said throttle valve, and a, second conduit connecting said orifice with the pressure actuated means.
4. The'combination with an internal combus tion engine having an intake passageway providedy with a throttle valve for controlling the flow of motive uid to the engine, means actuated through changes of pressure in the intake passageway on the engine side of said valve for imparting movement to said valve, a conduit connecting said pressure actuated means with the intake passageway onA the engine side of said throttle valve, a rotatable valve housing arranged to vary its speedin accordance with variations in the engine speed, said valve housing being connected into said conduit, and a centriiugally unbalanced valve in said housing rresponsive to changes in the speed of rotation of said valve housing for controlling said conduit, said centrifugally unbalanced valve tending to open said conduit when the engine reaches its governed speed to thereby decrease the pressure in said pressure actuated means and cause 40 said throttle valve to move toward closed position and tending to close said conduit when the engine falls'xbelow its governed speed to thereby increase the pressure in said pressure actuated means vand cause said throttle valve to move toward open position.
5. The combination with an internal combustion engine having an intake passageway provided with a throttle valve for controlling the ow of motive uid to the engine, means actuiated through changes of pressure in the intake passageway on the engine side of said valve for `imparting movement to said valve, a conduit 6. The combination with an internal combustion engine having an intake passageway provided With a throttle valve for controlling the ow of motive fluid to the engine, means actuated through changes of pressure in the intake passageway on the engine side of said valve for imparting movement to said valve, a conduit connecting said pressure actuated means with the intake passageway on the engine side of said throttlevalve, and valve means located in said conduit and responsive to changes in engine speed for controlling fluid flow through said conduit, said valve means tending to open said conduit when the engine reaches its governed speed and tending to close said conduit when the engine falls belowits governed speed, and an air bleed to atmosphere for said pressure actuated means positioned on the pressure actuated means side of said valve means.
'1. The combination with an internal combustion engine having an intake passageway provided With a throttle valve for controlling the ow of motive fluid to the engine, a suction device including a housing and ilexible diaphragm, a connection between the exible diaphragm and the said`throttle valve, a conduit connecting the inside of said housing with an orifice in the intake passagewayon the engine side of said throttle valve, and valve means responsive to changes in engine speed for controlling fluid flow through said conduit, said valve means tending to open said conduit when the engine reaches its governed speed and tending to close said conduit when the engine falls below its governed speed.
48. The combination as set forth in claim 7 including a second conduit connecting the inside of said suction device with an orifice in the intakeI passageway on the atmosphere side of said throttle valve.
9. The combination with an internal .combustion engine having an intake passageway provided with a throttle valvev for controlling the flow of motive uid to the engine, a suction device including a housing and iiexible diaphragm, a connection between the flexible diaphragm and the said throttle valve, a conduit connecting the inside of said housing with an orice in the i11- take passageway on the engine side of said throttle valve, a rotary valve housing connected into said conduit and arranged to'l change its speed of rotation in accordance with changes in the engine speed, ak centrifugally unbalanced valve mounted in said valve housing responsive to changes in engine speed for controlling fluid flow through said conduit, said centrifugally unbalanced valve tending to open said conduit when the engine reaches its governed speed and tending to close said conduit when the engine falls below its governed speed, a second conduit connecting the inside of said suction device with an orice in the intake passageway on the atmosphere side of said throttle valve.
