1 Claim.

The object of this invention is to admit air and positively prevent the admission of fuel during the deceleration of an automobile engine when the engine is driven by the car. The figure shows the preferred form of my invention.

In the figure, II] is the air entrance leading to a venturi II, into which discharges a nozzle l2, which is supplied with fuel from a passage I3. Low speed fuel is supplied from a passage I4, passage l5, passage l6 and is interrupted by a valve l'l, controlled by an electro-magnetic solenoid l8, which is grounded through a conductor A spring l9 pushes the valve l| into the 26. open position shown, which permits the fuel to flow freely to the passage 31. The main fuel nozzle |2 discharges into outlet 33 below the venturi II, which is controlled by a butterfly throttle 34, the upstream lip of which controls the low-speed outlets 3536 from passage 31', which discharges into mixture outlet 46.

An electric conductor 20 connects the first solenoid IS with a second solenoid 2|, which in its turn is connected through a conductor 22 to a differential micro switch 23, which is connected through a conductor 24 to a battery 25, which is grounded. The solenoid 2| attracts a balanced air valve 27, which is held on its seat by a spring 28. The valve 21 is balanced by means of a diaphragm 29 and an air passage 30 drilled in the An air passage 32 connects the air entrance III with the chamber 3| surrounding valve 21.

Diaphragm 40, located in the inlet manifold 41, engages with the arm 4| of the micro switch 23 through a slotted rod 42, which is connected by a spring 43 with an adjustment 44, which is locked in place by a lock nut 45.

Operation During deceleration, when the throttle 34 is closed far enough so that the car drives the engine and when the suction exceeds 21" Hg approximately, then the diaphragm moves the slotted link 42 far enough to engage with the rod 4| and to operate the micro switch 23. The solenoid |8 then draws the valve l1 to the left and blocks the path from I6 to 31, and the low speed fuel ceases to flow Meanwhile, the solenoid 2| draws the valve 21 upwards and admits air to the manifold 41.

Air continues to flow into the inlet manifold 41 until the suction has fallen to 14" Hg approximately when the diaphragm 40 moves far enough to reverse the switch 23. Then the spring l9 moves the valve I! to the right and the spring 28 closes the valve 2! as both solenoids cease to act.

What I claim is:

In an internal combustion engine having a carburetor and an inlet passage, a mixture outlet, a throttle valve therein, a low speed fuel passage, a valve in said passage, an auxiliary air entrance located on the engine side of said throttle, a valve in said auxiliary entrance, electro-magnetic means for opening said valve and closing the valve in the low speed fuel passage, a differential switch in series with said electromagnetic means, vacuum responsive means adapted to move said switch so as to energize said electro-magnetic means at suction greater than a predetermined suction and to release said electro-magnetic means at a substantially lower suction, yieldable means for closing the airvalve in the air entrance and for opening the Valve in the low speed fuel passage.

ELMER OLSON.
