摘要： PROBLEM TO BE SOLVED: To simplify passage constitution of a main fuel system and a low speed fuel system, to improve production efficiency and reduce a manufacturing cost, and to improve responsiveness and stability of a fuel supply. SOLUTION: A main fuel passage 14 and a low speed fuel passage 19 are longitudinally formed in a part between the central part of a constant fuel chamber 6 and two intake passages 2. A main nozzle 18 is connected to the upper end part of the former and the latter is bent from an upper end in a lateral direction and runs to a port for a low speed. Further, respective air bleed passages 24 and 26 are formed from the vicinity of the inlet of the intake passage 2 in a lateral direction and connected to the longitudinal parts of the fuel passages 14 and 19, respectively, as they are.

摘要： PURPOSE:To improve charging efficiency ever so better, by throttling a suction air path of a variable choke carburetor almost continuously from the suction side to the outlet side of the downstream of a throttle valve. CONSTITUTION:A suction barrel ranging from the opening side 2A of a variable choke carburetor to the outlet side 2B of the downstream of a throttle valve 19 is made so as to almost continuously throttled. At the point midway, a variable piston 10, a main nozzle 7 and the throttle valve 19 are set up. Thus, even if the suction barrel is almost continuously throttled, no influence is given to an Venturi effect and, what is more, since an air stream becomes smoothed enough, charging efficiency is thus improved.

摘要： PURPOSE:To reduce the cost of each of constitutional matters of a fuel injection unit and as well to prevent the output of an engine from being scattered due to the scattering of fuel injection, by lowering fuel supply pressure to the fuel injection unit and by making the fuel injection point into a mere dot. CONSTITUTION:The discharge side of a blower 22 connected to an intake pipe, is communicated with the upper fuel section in a constant fuel level meter 27. A nozzle 29 is disposed in a single intake pipe 27. When air fed from the blower 22 through a pipe line 23 pressurizes fuel in the constant fuel level meter 27, fuel which is metered through a measuring orifice 30, is forced out from the nozzle 29. The fuel forced out from the nozzle 29 is atomized when air fed from the blower 22 through the pipe line 23 passes through a blowing-off openings in the nozzle 29 for being injected together with air jet, and then, is fed to the engine 1 through a throttle valve 3. With this arrangement, no high pressure pipe lines are required, and the output of each cylinder of the engine is prevented from being scattered.

摘要： A method of making a carburetor by first extruding a length of material and then cutting a carburetor body (10) of predetermined length from the extrusion. The extrusion includes a passageway (14). A venturi member (40) is molded of plastic material and inserted in the passageway. A fuel bowl (54) is molded from plastic material and is secured to the body by means of a resilient clip (98).

摘要：本实用新型特别涉及一种抗振动化油器，沉淀杯内设有浮子，浮子可上下运动且传动给针阀的顶针杆来关闭或打开进油通道，浮子下方设有可使进油通道上的针阀始终不完全打开的限位挡体。本实用新型中由于浮子下端设有限位挡，所以当浮子运动到最下端时进油通道也只是不完全打开，可以保持供油量和需求量的平衡，保证混合气的充分燃烧，减少废气的排放，降低空气污染。
