摘要： PROBLEM TO BE SOLVED: To provide a throttle valve assembly, a torque motor assembly and a manufacturing method for increasing a winding area of a thin plate laminated body relative to the predetermined dimensions of a motor. SOLUTION: The motor-driven throttle valve assembly 110 is provided with a shaft 18 having an extending part arranged on the outside of a throttle main body 12, a hollow rotor 166 mounted on this extending part, a stator 134 coaxially arranged inside the rotor, mounted on the outer wall 86 having a plurality of magnetic pole parts wherein coils are spaced in a peripheral direction. The inner peripheral surface of the rotor is opposed to the outside of the magnetic pole of the stator, and a plurality of magnets 17 and 174 are arranged on this inner peripheral surface. The extending part of the shaft is mounted on a flange part 168 of the rotor for rotating and driving the rotor. Instead of shortening the dimensions of the motor or dispensing with a mounting shaft, more winding areas for conductive coils are given by welding, winding and integrating by a mold coating, and lines of magnetic force are increased.

摘要： PURPOSE: To well atomize fuel and improve combustible performance by forming a radial diffusion portion ranging downward from a nozzle with a nozzle section curved outward and a wall facing a throttle, the wall being provided with a curved portion projecting toward a throttle. CONSTITUTION: A nozzle 2 has a nozzle inner room limited with its inner wall 3 and tapered downward from its upper section 4 and ranging to the minimum cross section 5. A radial diffusion portion 6 is continued downward from the minimum cross section 5 and the downflow cross section of the diffusion portion 6 is gradually tapered toward the radial exit 19 of the diffusion portion 6 to be moved to a suction pipe 7. In this case, the diffusion portion 6 is formed with a nozzle section curved outward in the flow direction of a mixture, a structure 17 forming a structural unit 18 with the suction pipe 7 and a wall 15 facing a throttle 8, the wall 15 being provided with a curved portion 16 projecting toward the throttle 8.

摘要： PURPOSE:To prevent overspeed operation of an engine, by feeding fuel superfluously and thereby causing incomplete combustion of fuel by reducing the opening area at the inlet of a venturi by bringing a plate member having a small opening into abutment with the inlet of the venturi when the amount of intake air supplied to the engine is increased. CONSTITUTION:At the time of ordinary operatin of an engine, a plate member 7 is forced onto an inlet stopper 10 by the force of a spring 9 irrespective of the quantity of intake air, so that a proper amount of intake air is supplied to the engine through a main air port 11 formed in the plate member 7 and a proper number of auxiliary air ports 12 formed around the main air port 11. On the other hand, when a throttle valve 3 is fully opened under the state that the engine is operated with low or no load, the flow rate of intake air is increased rapidly, so that the plate member 7 is moved in the direction of air flow against the force of the spring 9 until it comes into abutment with the upstream end face 8 of a venturi 2. Resultantly, intake air is passed to the vanturi 2 only through the main air port 11, so that the negative pressure developed at the venturi 2 is increased drastically and a large amount of fuel is supplied from a main nozzle 5. Therefore, the engine causes incomplete combustion and the engine out put is lowered.
摘要翻译：目的：为了防止发动机超速运转，通过使文丘里管入口处的开口面积减小，通过使具有小开口的板构件与文丘里管的入口邻接而使燃料多余地进料，从而引起燃料的不完全燃烧，提供给发动机的进气量增加。构成：在发动机的普通操作时，通过弹簧9的力将板构件7强制到入口止动件10上，而与进气量无关，使得适量的进气供给到发动机通过形成在板构件7中的主空气口11和形成在主空气口11周围的适当数量的辅助空气口12.另一方面，当节气门3在发动机为低负载运行时，进气的流量快速增加，板材7克服弹簧9的力而沿空气流动方向移动，直到其与上游端面8邻接文丘里管2.因此，仅通过主空气口11将吸入空气传送到万太2，使得在文丘里管2处产生的负压急剧增加，并且从主喷嘴5供给大量的燃料。因此，引擎导致不完整燃烧和发动机出油降低。

摘要： PURPOSE: To quickly correct the mixture ratio of a mixture by controlling fuel with a fuel control mechanism in association with a throttle displaceable in a nozzle communicating with a suction pipe associated with an accel pedal to correct the controlled fuel in response to suction negative pressure. CONSTITUTION: Fuel pumped up by a pump 2 is supplied through a filter 3 and a pressure adjuster 4 to a control unit 6 in association with the motion of an accel pedal via a shaft 19. The control is conducted according to the position of a control mechanism 18 integrated with the throttle 11. The controlled fuel is supplied through a conduit section 7a to a combustion chamber 23 for a control adjuster 8 and sucked out to the narrowest cross section 12 of the nozzle 9 with a conduit section 7b. A conduit section 7d branching from the conduit section 7a is connected to a room 38 partitioned with a diaphragm 35 via the throttle 37 so that the volume of the room 38 is increased to reduce a fuel amount to be supplied to the nozzle 9 when suction negative pressure on the diaphragm 35 is increased.

摘要： PURPOSE:To improve atomization of fuel and provide a variable sonic nozzle carburetor with good responseability, by sucking fuel as preliminarily mixed with air at a second sonic nozzle into a first sonic nozzle as annularly formed. CONSTITUTION:When a valve 16a is opened and closed by operating accelerator pedal, a vacuum induction passage of an outlet 7 downstream of a variable sonic nozzle 21 is opened and closed to adjust a vacuum in a chamber 14 of a diaphragm 12 thereby raise and lower a nozzle member 8 forming the variable sonic nozzle 21. In response thereto, an opening degree of a fuel nozzle 31 is adjusted by a needle 33, and a metered fuel is mixed with air flowing from an opening 6 through a passage 34 to a fixed sonic nozzle 32. Such a preliminarily mixed fuel is sucked to the variable sonic nozzle 21, and is completely atomized to be uniformly distributed to each cylinder of an engine.
