摘要： A carburettorfor engines of motorvehicles has a suction conduit (1) fed by fuel from a chamber (3) in which the fuel level is kept constant by a needle valve actuated by a float system with two floats (14, 15), the walls (5, 6, 7, 8) which delimit the chamber (3) laterally are vertical and vertical are the outer surfaces of the two floats (14,15), particularly those facing the walls of the chamber (3), on the vertical line passing through the centre of gravity (33) of the figure (39) defined by sectioning a horizontal plane by the spatial figure included between the inner walls of the chamber (3) and the outer surfaces of the floats (14,15) there is the main jet which is supported by a columnar structure having vertical walls, suspended from the cover of the carburettor, and which accommodates the main and idling circuits of the carburettor; the planes of the level of the fuel contained in the chamber section the floats according to figures whose static moments relative to the fulcrum of the closure lever of the needle valve are substantially constant as the inclination of the carburettor relative to the horizontal plane varies.

摘要： A carburetor float bowl. The float bowl includes a float adapted to be flotationally supported by liquid fuel in the float bowl over a predetermined range of the level of fuel therein. A fuel inlet is adapted to direct fuel along a line toward the floor of the float bowl. The float bowl further includes a “fuel chute” having a ramping surface, a portion of which is intersected by said line at a point thereon. The ramping surface is disposed to provide a ramp angle at the point with respect to the floor that is substantially greater than 90 degrees and substantially less than 180 degrees.

摘要： An attachment for a fuel carburetor possesses a fuel inlet, a needle-and-seat valve disposed in the inlet, and a float attached to the needle-and-seat valve. In one embodiment, the attachment is placed between and is in fluid communication with both the float bowl and the metering block of a typical carburetor. Fuel is pumped into the float bowl and the attachment in parallel from the fuel pump. The float in the attachment rises and falls according to the level of fuel in the interior of the attachment and float bowl, and thus regulates the position of the needle-and-seat valve, which in turn regulates how much fuel is pumped into the attachment and float bowl. The attachment is also provided with a device for injecting a spurt of fuel directly into the metering block to avoid lean fuel conditions when the throttle is initially opened. In an alternative arrangement, the float bowl and attachment are made as one integral unit. In another embodiment, two attachments and an end cap are mounted on the metering block and the float bowl is not used.

摘要： A carburetor float bowl is provided which is elongated in a direction lengthwise of the vehicle and has a smooth upwardly curved section on the bottom wall at the front and rear ends of the float bowl to minimize sloshing of the gasoline and also minimize foaming of the gasoline within the float bowl during severe back and forth rocking movement of the carburetor as would occur in a motorcycle passing over a series of bumps at a high speed.

摘要： A carburetor comprising a body defining a throat, a throttle slide member slidably mounted on the body and disposed in the throat, a rotary actuator for the slide member, and a tapered metering rod or needle mounted on the slide member and extending downwardly into a fuel supply tube leading into a sealed and pressurized fuel reservoir or bowl secured to the body. The slide member has front and rear, substantially flat panels disposed in substantially parallel relation, with the front panel being shorter than the rear panel for the purpose of providing air at the outlet of the fuel supply tube even when the slide is in a closed position and for directing air toward and around the outlet when the slide is in an open position. The bottom of the rear panel has a cut-out portion in alignment with the metering rod and fuel outlet at the throat for the purpose of directing high speed air flow toward the metering rod and around the fuel outlet. The metering rod is provided with a downwardly and inwardly tapered, rear flat face and is mounted for longitudinal adjustment relative to the slide member. A shroud surrounds the forward face of the rod adjacent the fuel outlet to reduce turbulence, and an air supply channel surrounds the fuel outlet to promote a balanced system and an optimum fuel-air ratio.

摘要： A carburetor for a multi-cylinder internal combustion engine which has for each cylinder a main combustion chamber defined above the piston in the cylinder and a sub-combustion chamber defined above the main combustion chamber and communicating with the latter through a torch nozzle. The carburetor has a main intake passage and a sub-intake passage for supplying a comparatively lean mixture and a comparatively rich mixture to the main and sub-combustion chambers respectively. The carburetor has a single throttle valve shaft extending across the main and sub-intake passages with a main throttle valve and a sub-throttle valve mounted on the valve shaft and disposed in the main and sub-intake passages respectively. One of the main and sub-throttle valves has an outside diameter smaller than the inside diameter of the associated intake passage so that the ratio of the open areas of the main and sub-intake passages is not constant as the throttle shaft is operated. Thereby, the ratio of weight of air introduced into the sub-combustion chamber to the weight of air introduced into the main combustion chamber can be controlled in accordance with the load condition of the engine.
摘要翻译：一种用于多缸内燃机的化油器，其对于每个气缸具有限定在气缸中的活塞上方的主燃烧室和限定在主燃烧室上方的副燃烧室，并且通过割炬喷嘴与其连通。化油器具有主进气通道和副进气通道，用于分别向主燃烧室和副燃烧室供应比较稀的混合物和较浓的混合物。化油器具有单个节流阀轴，其横跨主进气通道和副进气通道延伸，主节流阀和安装在阀轴上的副节流阀分别设置在主进气通道和副进气通道中。主节气门和次节气门之一的外径小于相关进气通道的内径，使得主节气门和副进气通道的打开区域的比例在节流轴被操作时不是恒定的。由此，能够根据发动机的负载条件来控制引入副燃烧室的空气的重量与引入主燃烧室的空气重量的比例。

摘要： A carburetor for an internal combustion engine comprises a control for maintaining the pressure of the fuel supply through the carburetor constant. The control includes a sensing device, which is preferably a level sensing device, and a fuel feed valve which is automatically operated by the sensing device. The sensing device produces signals which operate the valve to control the rate of fuel supply to the carburetor and, in order to provide an indication of the instantaneous rate of fuel consumption of an engine to which the carburetor is fitted, these signals are also fed to a fuel flow indicator. The fuel flow indicator produces a reading of the fuel flow rate either in dependence upon the frequency of opening of the valve when the opening period is constant, or in dependence upon the period for which the valve is open when the frequency of opening of the valve is constant.
