摘要： An improved mechanical air-fuel blending system for use with internal combustion engines, in which a highly compressed fuel such as Liquified Petroleum (LP), is throttled at its storage pressure across a single fuel valve before entering a fuel flow divider which allows the main portion of the discharged LP to flow directly into the air stream before passing to the internal combustion engine. A small portion of the discharged fuel, termed the control fuel, is separated within a fuel flow divider and is diverted across one or more heat exchangers, where it transfers heat to and from the incoming air charge which brings the temperature of the control fuel to that of the incoming air, before entering the air stream at the venturi across one or more orifices. The control fuel pressure within the heat exchanger is compared with the free air pressure entering the system, across a light diaphragm to control the positioning of a fuel valve.

摘要： A crankcase fuel injection system includes a diaphragm type fuel pump, a crankcase fuel injector assembly, and a main air inlet assembly. Engine crankcase pulses generated by the up and down movements of the piston are utilized by the fuel pump to replenish the fuel mixture in a fuel mixture injector chamber of the fuel injector assembly. The air mass entering the crankcase upon the upstroke of the piston is controlled within the main air inlet assembly by a throttle valve and metered across a main air venturi. The venturi signal at the main air venturi is amplified by a booster venturi. The amplified venturi signal is applied to a middle chamber formed between the two diaphragms of the compound diaphragm assembly which serves as the injector pump mechanism. The force acting upon the diaphragm assembly due to the amplified venturi signal is further amplified due to the area relationships of the two diaphragms. The resulting amplified force creates an inward movement of the compound diaphragm assembly which injects a fuel charge from the fuel chamber under pressure into the crankcase across a check valve and a fuel injector orifice. The air-fuel ratio is trimmed using an aneroid chamber or a trim adjustment screw to control the addition of bleed air into the amplified venturi signal.

摘要： A fuel sensing diaphragm and an air sensing diaphragm apply opposing forces to a transfer member. The forces applied by the fuel sensing diaphragm are based upon the flow rate of fuel, and the forces applied by the air sensing diaphragm are based upon the air flow rate through a venturi. The fuel sensing diaphragm, transfer member, and air sensing diaphragm move together as a control unit which controls the amount of free air allowed to enter an air chamber. Free air in the air chamber is bled off across a vacuum orifice connected to a vacuum port below the throttle plate. The air chamber is in fluid communication with a regulator air chamber. The regulator air chamber is separated from a regulator fuel chamber by a regulator diaphragm and plunger. The regulator diaphragm and plunger operates a fuel inlet ball valve which controls the flow of fuel. A regulator diaphragm and plunger operates the fuel inlet valve based on the pressure in the regulator fuel chamber, the pressure in the regulator air chamber, and the force of a regulator spring. Fuel is discharged through a fuel discharge into an accelerated air stream caused by an air orifice. The mixture of accelerated air and discharged fuel enter the main air stream below a throttle plate. Changes in air density are compensated for by an aneroid chamber regulating the pressure differences on the air sensing diaphragm, which alters the forces the air sensing diaphragm applies to the transfer member.

摘要： A single pivoting diaphragm plate is utilized to separate the two air-sensing chambers and the two fuel-sensing chambers. The diaphragm plate is bonded to a resilient diaphragm/seal which separates and seals the four chambers and allows for the pivoting action of the diaphragm plate as it seeks to balance the forces of the air velocity and the fuel velocity. Any imbalance between the forces is sensed across the diaphragm plate, which immediately results in a pivoting movement to return the system to a balanced condition. The pivoting action of the diaphragm plate controls the fuel discharge valve which feeds fuel into an accelerated air passageway which enters the main air stream below a throttle plate.

摘要： A device for the blending of gases or liquids having an inlet adapter, a main body, an outlet adaptor, a valve plate, and a spring arm. Air enters the inlet adaptor and passes through an air port in the main body. Fuel is supplied to a fuel port in the main body through a nipple and a passage. The fuel port and the air port share a common valve seating plane and are aligned side by side along the innermost edge of the valve seating plane. The spring arm applies a force to the valve plate which forces the valve plate towards the valve seating plane. The valve plate pivots about the innermost edge of the valve seating plane in response to the downstream demand for the blend and forms a common angle above the air and fuel ports, which results in proportionally exposed port areas. The downstream demand for the blend provides a pressure difference across the valve plate which acts against the valve plate spring to position the valve plate to a balanced position. Air and fuel from the air port and the fuel port exit the blending device through the outlet adapter. Any change in the downstream demand results in the repositioning of the valve plate.
