摘要： A staged multi-barrel carburetor (C) has two air induction passages (P) and first and second throttle valves (T1,T2) one of which is positioned in each of the respective induction passages. The first throttle valve (T1) is operable to open prior to the second throttle valve (T2) opening, and a countershaft (CS) is interconnected with the first throttle valve for rotation therewith as it opens and closes. The countershaft is interconnected (1) with the second throttle valve to open it as the first throttle valve opens, but not until the first throttle valve has opened to a predetermined open position (15). Opening movement of the second throttle valve, after the first throttle valve has opened to its predetermined open position, is delayed (21) if engine vacuum exceeds a predetermined level thereby to prevent lags in engine performance which may occur during engine acceleration.

摘要： An air-fuel mixture intake apparatus for internal combustion engines includes a two-barrel carburetor having a primary venturi for supplying an air-fuel mixture into a combustion chamber under all loads and a secondary venturi for supplying an air-fuel mixture into the combustion chamber under medium and high loads. The primary venturi is of a fixed cross section and the secondary venturi is of a variable cross section. A vacuum-operated actuator controls operation of a secondary throttle valve in response to a vacuum developed in the primary venturi and subsequently in the secondary venturi. The secondary throttle valve is interlinked with a primary throttle valve by a linkage mechanism such that the secondary throttle valve is allowed to open when the primary throttle valve opens to a predetermined degree with the maximum opening of the secondary throttle valve being variably controlled by the opening of the primary throttle valve after the latter has opened beyond the predetermined degree. A delay valve is disposed in a primary vacuum signal passageway or a common vacuum signal passageway connected to a vacuum chamber of the vacuum-operated actuator to delay an air flow through the passageway toward a vacuum pickup probe in the primary venturi. The secondary throttle valve may be mounted on a shaft displaced downstream off the geometric center of the secondary throttle valve.

摘要： A carburetor assembly has primary and secondary venturi passages to supply a lean mixture to main combustion chambers of an engine, and has an auxiliary venturi passage to supply a rich mixture to auxiliary combustion chambers of the engine. A throttle valve in each passage is provided with a shaft, and the shaft for the primary throttle valve projects through a hollow hub on the carburetor body. Several members and springs are mounted on the hub and serve to control turning movement of all throttle shafts during various operating conditions of the engine. A link is pivotally connected at one end to an arm which turns with the primary throttle valve and is pivotally connected at the other end to an arm which turns with the auxiliary throttle valve. An angular adjustment is provided between the auxiliary throttle valve and its respective arm. The geometric relationships of the link and arms are such as to provide the desired coordinated movement between the throttle valves.

摘要： A carburetor for an automotive internal combustion engine has primary and secondary barrels, each of which contains an air intake passage, a venturi and a throttle valve arranged in the air intake passage. The secondary throttle valve is adapted to open in response to the resultant of the primary and secondary venturi vacuums. The opening of the secondary throttle valve is, however, obstructed to suppress an unnecessarily rapid increase of engine speed.
