United States Patent ANTISTALL DEVICE Richard R. Goodwin, Ferndale, Micln, assignor to Holley Carburetor Company, Detroit, Mich, a corporation of Michigan Application September 9, 1952, Serial No. 308,665
1 Claim. (Cl. 267-1) The object of this invention is to prevent the stalling of an engine on a 1952 car having an automatic transmission. The stalling trouble became critical when automatic transmissions became standard equipment on cars. i
When the throttle is closed, ther spark is retarded and the low speed fuel is almost cut off; however, prior to that, excessive fuel is put in the. manifold by the action of the carburetor accelerating pump. The abrupt cut off of the air supply and the lowering of the pressure in the manifold converts the wet fuel into vapor and an excessively rich mixture results. The action of the automatic transmission decelerates the engine so rapidly that the engine chokes.
More specifically, here is the sequence of events: Upon depressing the accelerator pedal when at a stop and then quickly releasing same, the intake manifold is loaded with fuel. The load constantly imposed upon the engine by the automatic transmission rapidly decelerates the engine. The throttle being closed, the engine is exposed to an excessive gasoline mixture and it, therefore, tends to stall. If the throttle is held open for a very short time, more air is allowed to enter the manifold, thereby reducing the fuel-air ratio and permitting the engine to continue to operate.
Figure 1 shows in cross-sectional elevation my invention.
Figure 2 is a plan view of the novel element of my invention taken on plane 2-2 of Figure 1 In the figures:
12 is the low speed fuel passage.
14 is the high vacuum ignition passage.
16 is the butterfly throttle which cooperates with the outlets 18, 20 and 22 of the passages 12 and 14 and is mounted on the throttle shaft 30.
24 is the throttle lever.
2,696,980 Patented Dec. 14, 1954 26 is the throttle stop.
28 is the retarder rod.
32 is the diaphragm which carries the rod 28.
36 is the lip of the diaphragm 32.
34 is the air chamber which operates the rod 28.
38 is the spring which returns the rod 28 to its ex treme advanced idle positiona spring not shown engages the hole 40 in lever 24 and is calibrated to overcome spring 38 at a certain rate.
42 is a leak which is calibrated to act with these two springs and to give the desired result.
44 is a metal disc supporting diaphragm 32.
46 is the seat for the spring 38.
48 is the wall of the chamber 34.
Operation When the throttle is released and the spring (not shown) connected to the hole 40 in lever 24 pulls 40 to the left, the spring 38 resists and is assisted by the air inside the chamber 34 which slowly leaks past the flap 36 and along the small slot 42. The time of return is determined by the spring engaging the hole 40 in lever 24 of the spring 38 and by the size of the leak path 42. 52 is the idle stop on lever 24 and 54 is the adjustment in support 56.
What I claim is:
A retarder for the closing movement of inlet throttle valve of an automobile engine comprising a chamber, a compression spring therein, a circular flexible diaphragm forming one wall of said chamber and engaging said spring, a central supporting disc for said diaphragm, an opening therein, said diaphragm having three cuts made therein; one at right angle to a radius, the other two at right angles to said first cut in said diaphragm so as to form a retarder flap which almost completely covers said opening so as to freely admit air to said chamber when the spring expands and retard the rate at which the said spring is compressed.
