ABSTRACT:
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.
