    Abstract: A pneumatic pressure control system which controls the ratio of fuel to air in the intake manifold of the engine includes a valve assembly which is operative in response to the combined action of the negative pressure existing in the intake manifold and positive pressure from an air pump operated by the engine. When the sum of the negative and positive pressures acting on opposite sides of a diaphragm are sufficient to overcome a spring force on the negative pressure side of the diaphragm the movement of the diaphragm will cause the operation of the valve to admit atmospheric air pressure either directly into the intake manifold or to a fuel regulating device to operate a further valve to reduce the supply of fuel to the carburetor.

    Abstract: A carburetor for an internal combustion engine has an idle or low speed system in which air is bled into the idle fuel passage. An air bleed valve member controls the amount of air flow through an air bleed port for the idle fuel passage and a diaphragm operated control is connected to the air bleed valve member to control the movement of the valve member. The diaphragm operated control has an air chamber on one side of the diaphragm and a vacuum chamber on the other side of the diaphragm with a restricted opening between the air and vacuum chambers. Upon a rapid engine deceleration to an idle position, the air bleed valve member is moved to a position to provide maximum air flow to the idle fuel passage for a limited period of time until the pressure is equalized between the vacuum chamber and the air chamber through the restricted opening. Such an arrangement permits fuel which has previously condensed on the walls of the manifold to be leaned for a short period of time after a rapid increase in intake manifold vacuum which results from rapid engine deceleration to an idle position.

    Abstract: A carburettor having a slow running jet with a device for controlling the output of the slow running jet during deceleration. The device comprises an axially movable closure member inside the jet, its axial movements being dependent upon the magnitude of depression downstream of the normal butterfly throttle. The closure member has passage means allowing fuel flow to pass from a fuel inlet into the slow running jet and its movements are controlled by a diaphragm acted upon at one side by atmospheric pressure and on the other side by the pressure prevailing in the downstream side of the carburettor or the induction manifold.

    Abstract: A fuel control arrangement for an internal combustion engine includes a speed-responsive valve in a passage communicating with the inlet manifold of the engine. An actuator is responsive to the pressure in the manifold and to the pressure in the passage on a side of the valve remote from the manifold, to operate a fuel valve for the engine, the arrangement being such that when the engine speed is above a predetermined level and the manifold pressure is below a predetermined level, fuel flow to the engine is reduced.
