摘要： A carburetor with a throttle valve is provided in which a linkage member is in communication with the throttle valve. An idle down handle can be moved from an unactuated position to an actuated position and is in communication with the throttle valve. Movement of the idle down handle to the actuated position causes the throttle valve to be placed into the closed position. When the idle down handle is in the unactuated position the throttle linkage member can cause the throttle valve to be moved back and forth between the open and closed positions.

摘要： A charge forming device includes a body with a fuel and air mixing passage, a bypass passage that communicates with the fuel and air mixing passage, a throttle valve and a choke valve. The throttle valve is movable between idle and wide open positions and operable to control at least in part the fluid flow through the fuel and air mixing passage. The choke valve is movable between an open position permitting a substantially free flow of air into the fuel and air mixing passage and a closed position at least substantially restricting air flow into the fuel and air mixing passage. A bypass valve is movable between an open position and a closed position to selectively permit fluid flow through the bypass passage. The bypass valve is movable toward its open position when the throttle valve is displaced at least a threshold amount away from its idle position.

摘要： The invention is directed to a carburetor for an internal combustion engine and includes an intake channel having a throttle flap mounted therein. Fuel passes from a fuel-filled control chamber via channels to main and idle nozzles through which the fuel enters the intake channel. The maximum permissible fuel quantity must be adjusted during a test run be means of an adjusting screw. This value can be changed by an operator. The maximum flow cross section for the fuel throughput is limited by at least one fixed throttle to which the main nozzle and the idle chamber are connected at the downstream end. In this way, strict exhaust-gas limit values are maintained. An adjustable throttle is provided with the aid of which the entire flow cross section can be reduced up to a pregiven minimum value. The carburetor described above is especially suitable for two-stroke engines of portable handheld work apparatus.

摘要： A diaphragm carburetor with both the main metering nozzle and an idle circuit supplied with liquid fuel from the same metering chamber and an accelerator and shut-off assembly in the idle circuit. The assembly has a valve which is open to supply fuel to the idle circuit when the throttle is in a closed idle position and closes off the supply of fuel from the metering chamber as the throttle is moved to its wide open position. Opening of the throttle also actuates a piston to supply additional fuel for accelerating an engine.

摘要： An outboard motor having a charge forming system including an enrichment fuel device that supplies additional fuel and air to the engine for starting and warm up. The fuel and air are supplied from one charge former of the engine and are delivered to a balance passage of a spacer between the charge formers and the intake manifold. The additional air supplied by the enrichment device is drawn from an air circuit of the carburetor so as to reduce the discharge pressure of the fuel discharge circuits of the carburetor to draw additional enrichment fuel from those discharge circuits when the enrichment device is in operation.
