摘要： A scavenging carburetor having an improved relationship between scavenging air flow and fuel-and-air flow to an engine over its range of operating conditions. The carburetor has a butterfly throttle valve and a plug-type scavenging valve. Levers are attached to support shafts of the valves and are connected to each other by a connecting rod so as to synchronize movement of the valves. Because of the different opening angle versus open area properties of the two valves, the supply of the scavenging air is minimized over a low speed range of the engine so as to achieve a stable low speed operation and a stable acceleration from idle conditions and a relatively large amount of scavenging air is supplied over a high speed range of the engine for the given amount of fuel-and-air mixture that is supplied. Therefore, the fuel-and-air mixture supply and scavenging air supply is better matched to the requirements of a particular engine than was possible with conventional combinations of valves.

摘要： A carburetor for a stratified charge two cycle engine with a choke bore, venturi, and throttle bore configuration matching an irregularly shaped choke valve. The trailing and leading edges of the choke and throttle valves, respectively, preferably overlap during wide open throttle operation to separate a single intake passage bore into an air intake passage above the choke and throttle valves and an air/fuel intake passage below the choke and throttle valves. The choke valve is preferably bent to minimize operational rotation and limit fuel spit back.

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： A versatile rotary carburetor has an idle adjustment needle, a high speed adjustment needle, and preferably an air bypass screw which are substantially parallel to one another and are axially exposed for adjustment in a substantially common direction. Preferably a cammed rotary throttle valve is seated in a body of the carburetor for rotation about and axial movement along an axis. The rotary throttle valve intersects a mixing passage in the body, and carries a through-bore that variably generally aligns to the mixing passage upon rotation of the throttle valve. The throttle valve projects axially through an external surface of the body and threadably receives the idle adjustment needle oriented concentrically to the axis. A primary fuel feed tube disposed concentrically to the axis projects into the through-bore to receive the idle adjustment needle at an open distal end which variably obstructs an orifice in a cylindrical wall of the tube that generally communicates with the through-bore for delivering liquid fuel to the mixing passage. The high speed adjustment needle is preferably threaded to the body for adjustably intersecting and obstructing a fuel passage in the body that flows liquid fuel to the fuel feed tube for the flow of liquid fuel. Preferably, the air bypass screw threads into the body for adjustably intersecting and obstructing an air bypass passage in the body communicating at both ends with the mixing passage for generally bypassing the rotary throttle valve when in an idle position.

摘要： A carburetor has an air intake passage, a fuel passage, a fuel nozzle in communication with the fuel passage and having an opening through which fuel flows, a first valve in communication with the air intake passage and being movable between first and second positions, and a second valve in communication with the fuel nozzle and also being movable between first and second positions to vary the effective flow area of the fuel nozzle. The fuel nozzle is preferably carried by a tube fitted sealably in a bore being in communication with the fuel passage. The opening is defined by the tube and is preferably elongated, extending axially with respect to the tube. A needle of the second valve moves axially within the tube to variably obstruct the opening to control fuel flow. Preferably, a method of manufacturing the tube utilizes a circular cutting tool which plunges into the tube cutting a slit as the opening having a sharp peripheral edge for atomizing the fuel.

摘要： A carburettor for a two stroke engine includes a flow duct comprising rich and lean flow passages (160, 150) in parallel, through which, in use, air flows in a flow direction and which are separated by substantially planar partition (130). At least one fuel jet (5) communicates with the rich passage (160) and the partition includes an aperture (140) towards which the fuel jet is directed. A substantially planar butterfly valve (120) is received in the aperture so as to be pivotable between a first position, in which the flow duct is substantially closed and the aperture is substantially open, and a second position, in which the flow duct is substantially open and the aperture is substantially closed. The upstream half of the aperture (140) is defined by upstream semi-annular seating ledge (148) affording an upstream seating surface (151), which is engaged by one of the surfaces of the butterfly valve (120), when it is in the second position, and a first end surface (153), which extends between the upstream seating surface and that surface of the partition which is directed towards the lean passage. The downstream half of the aperture (140) is defined by a downstream semi annular seating ledge (149) affording a downstream seating surface (151), which is engaged by the upper surface of the butterfly valve, when it is in the second position, and a second end surface (161), which extends between the downstream seating surface and that surface of the partition which is directed towards the rich passage. At least one of the upstream semi annular seating ledge, the downstream semi-annular seating and the valve are so shaped that, in use, a pressure differential is created between the rich and lean passages at the upstream and/or downstream edges of the valve, the pressure in the lean passage being higher than that in the rich passage.

摘要： A carburetor (18) has a carburetor housing (17) wherein an intake channel (19) is guided having a flow cross section of less than 3 cm2. The carburetor (18) includes a partition wall (11) which partitions the intake channel (19) into a mixture channel (21) and an air channel (8). The partition wall (11) runs in the longitudinal direction of the intake channel (19). The carburetor (18) has a throttle flap (24, 64) pivotally journalled on a throttle shaft (25, 45, 55, 65, 75). A venturi (23) is formed upstream of the throttle shaft (25, 45, 55, 65, 75) in the mixture channel (21). A fuel opening (28) opens into the mixture channel (21) at the venturi (23). A device for dethrottling the mixture channel (21) and/or for dethrottling the air channel (8) is provided in order to compensate or equalize the nonuniform throttling of the air channel (8) and the mixture channel (21) by the throttle flap (24, 64).
