Abstract: A fuel delivery system for delivering fuel from a fuel tank to an internal combustion engine has a fuel pump with a pump inlet and a pump outlet, a fuel reservoir with a reservoir outlet, and a chamber connecting the pump inlet with the reservoir outlet. A reservoir supply valve between the reservoir outlet and the chamber is moved between an open position in which fuel flows from the reservoir to the chamber and a closed position in which fuel is prevented from flowing from the reservoir to the chamber, by a fuel level sender having a float arm which depresses or releases a plunger extending from the reservoir supply valve. A float attached to the float arm rises and falls with changes in fuel level within the fuel tank so as to contact the plunger and thus move the valve between the open and closed position when the tank fuel level is below and above, respectively, a predetermined level.

Abstract: A fuel delivery system has a fuel pump which draws fuel from a fuel tank to supply pressurized fuel to the fuel metering system of an internal combustion engine, and a conduit connecting the pump intake with an enclosed, pressurizable fuel reservoir for accumulating return fuel therein so as to provide a ready source of liquid fuel to the pump during conditions which cause insufficient fuel availability at the pump intake, such as low fuel tank level, sudden cornering, or grade parking. Pressurized return fuel fills the reservoir until a predetermined overflow pressure is reached and an overflow valve opens to allows fuel overage to flow into the fuel tank. When the fuel level in the tank drops below a predetermined level, the fuel level sender arm attached to the reservoir depresses a plunger to shut the overflow valve.

Abstract: Displacement of an object from a sensor is detected using a fiber optic a discharge end of which is arranged adjacent to the space from the object. Light passing along the fiber optic is reflected at the discharge end and is also reflected by the object at a position spaced from the discharge end. These two reflected parts of the light interfere causing an interference pattern. The light path from the discharge end to the object is cyclically varied using a sinusoidal dither obtained either by physical movement or by electro-optical means. This allows the output from the photo diode detecting the return reflected light to be analyzed as an alternating signal varying over time rather than as a simple comparison of absolute values as is used in the conventional techniques.

Abstract: A fuel supply system for an internal combustion engine 10 includes a fuel tank 14, a pump 12 having an inlet 16 for receiving fuel from the tank, and an outlet 18 for transferring fuel to the engine. A fuel supply line 20 extends from the tank to the inlet of the pump, and a fuel return line 22 extends from the engine to the inlet of the pump such that fuel may be recirculated from the engine to the pump inlet without passing into the tank.

Abstract: A fuel reservoir system for an internal combustion engine includes a canister (22) having a storage volume (24) for holding fuel, at least one fuel supply line (26) extending from the canister to the engine, an entrance pipe (28) for conducting raw fuel into the canister, and an exit pipe (32) connected with a fuel supply line for conducting fuel from the canister to the fuel supply line. The exit pipe includes a draft tube (34) extending into the lower part of the storage volume, a purge passage (36) communicating the upper portion of the draft tube with the storage volume, and a flow restrictor (38,40) mounted in the draft tube upstream of the purge passage.
