Abstract: PURPOSE:To improve starting performance while simply increasing fuel at engine starting by elevating only a needle using a cam at the starting in a carburetor wherein the amount of sliding of a sliding type throttle valve is made higher than that of the needle. CONSTITUTION:A lever 40b is turned around a shaft 36 by the anticlockwise rotation of a throttle lever 38 end to cause a slide type throttle valve 16 pin-connected to said end part to be elevated. On the contrary, an arm 60b in which a pin 60c mades contact is clockwise turned around a supporting point 60a by the rotation of the lever 40b to cause a shaft 52 equipped with a pin 82 making contact onto the arm 60b via a spring 58 to move upward and a needle 50 on the lower end of the shaft 52 to move upward, and thereby the degree of a fuel nozzle opening 34 is made wider, allowing a more fuel to be supplied. At engine starting, the anticlockwise rotation of a lever 88 causes a cam 90 to be turned around the shaft 86 to force the arm 60b to be clockwise turned via the pin 60c and thus the needle 50 to be moved upward, hereby enabling the fuel to be increased.
Abstract translation: 目的：为了提高启动性能，而简单地增加发动机起动时的燃料，只需在化油器起动时使用凸轮提升针头，其中使滑动式节流阀的滑动量高于针头的滑动量。 构成：杆40b通过节流杆38端的逆时针旋转而绕轴36转动，使得与所述端部销连接的滑动式节流阀16升高。 相反，通过杆40b的旋转，其中销60c阴极接触的臂60b绕支撑点60a顺时针转动，使得配备有销82的轴52经由弹簧58与臂60b接触， 向上移动并且轴52的下端上的针50向上移动，从而使燃料喷嘴开口34的程度更宽，允许更多的燃料供给。 在发动机启动时，杠杆88的逆时针旋转引起凸轮90围绕轴86转动，以迫使臂60b经由销60c顺时针转动，从而使针50向上移动，从而使得燃料 增加。

Abstract: PURPOSE:To decrease the total height of a carburetor, by heightening the mixture concentration of the carburetor in the starting and cold running of an engine without using a choke valve. CONSTITUTION:Sucked air sent from a pump 22 has its pressure regulated to a prescribed level by a constant pressure valve 23 and then jets out at a high speed through an orifice 30 and an ejecting section 31 so that intense negative pressure is caused at a pressure drop section 32. Since the negative pressure in a pressure introducing chamber 21 is made more intense than conventional cases and a sucked air flow rate detector 6 heightens the degree of opening of a Venturi valve 4, the effective cross-sectional area of a fuel jet 9 is made larger than the conventional cases so that the mixture concentration of a carburetor is increased in the starting and cold running of an engine. The high speed of the flow jetting from the ejecting section 31 is controlled by the orifice 30 and a regulating rod 29 depending on the temperature of the engine.

Abstract: PURPOSE:To prevent suction air from leaking in the atmosphere via an exhaust circulation valve mechanism, by installing a leakage preventive device closing an exhaust circulating passage at the suction system side simultaneously with the exhaust circulation valve mechanism being closed as pressure inside the suction system goes up beyond atmospheric pressure. CONSTITUTION:In case of an EGR device interconnecting a spot at the more downstream than a carburetor 7 in a suction system at the more downstream side than a supercharger 4 and an exhaust system 3 at the more upstream side than the supercharger 4 through an exhaust gas circulation (EGR) passage 8 and installing a suction pressure operating type valve mechanism 9 jointly in the said passage 8, an on-off valve 30 inclusive of a valve body 40 opening or closing the EGR passage 8 at the side of a suction system 1 nearby the valve mechanism 9 is installed. The on-off valve 30 is formed so as to open or close the valve body 40 by means of actuation of a diaphragm type actuator 33, which makes the suction pressure a driving source via an actuating rod 38. And, when pressure inside the suction system 1 goes up beyond atmospheric pressure, the valve body 40 is fully closed whereby an air-fuel mixture leakage into an atmospheric pressure chamber 14 through the EGR passage 8 at the side of the suction system 2 is prevented.

Abstract: PURPOSE:To obtain an almost maximum value of efficiency obtained from combination between intake throttling and an exhaust gas recirculation (EGR) rate, by driving an intake throttle valve and an EGR valve through a control actuator and decreasing a work loss due to a pressure drop of the intake throttling. CONSTITUTION:An exhaust gas recirculation (EGR) valve 16 is left as fully closed, and if an opening of an intake throttle valve 10 is adjusted to be aligned to a point C, required torque T is once satisfied, here thermal efficiency is as shown by (c). Then the valve 10 is slightly opened to be aligned to a point D simultaneously the valve 16 is opened little by little, and when the required torque T is satisfied, the thermal efficiency becomes (d). Again the valve 10 is slightly opened and aligned to a point E, and the valve 16 is set to an opening satisfying the torque T. Here the thermal efficiency becomes (e). Repeating similar operation, if efficiency obtained from combination between the preceding openings of the valve 10 and 16 is arranged to be higher than the efficiency obtained from combination between the new openings, the valves are set to the combination between openings in one point before. In this way, of the thermal efficiencies obtained from combination between openings of the both valves, almost maximum thermal efficiency is obtained.

Abstract: 1475451 Fuel-air mixture homogenizing apparatus P AUGUST 14 Jan 1975 [22 Jan 1974] 1448/75 Heading F1B An extra air admission device for the inlet manifold of an I.C. engine comprises a member 11 located downstream of a carburetter and provided with a pair of opposing slots 3, 7 connected to an air supply and dimensioned so that air passing through them exceeds sonic velocity. During engine idling, air enters only through slot 3, while at part-load air also enters through slot 7 under control of a throttle valve (not shown) linked to a carburetter throttle valve (also not shown). Recirculated exhaust gas may also be introduced via slot 7. At full load the slot 7 is not supplied with extra air. In the modification shown in Fig. 4, the mixture is heated in a heat exchanger 59 supplied with exhaust gases. Additionally an electric heating element 58 is provided.

SOLUTION: This relief valve is disposed in a fuel vapor discharge passage, and discharges the fuel vapor in a fuel tank into the discharge passage when the pressure in the fuel tank is equal to or higher than a predetermined value. The relief valve comprises a valve element storage part 70, an opening part 76 formed at one end of the valve element storage part, a valve element 80 so slidably disposed in the valve element storage part 70 as to open and close the opening part 76, and a spring 90 pressing the valve element 80 toward the opening part 76 and so elastically biasing the opening part 76 as to close it at all times. The valve element 80 comprises a metal base body 81 and a rubber membrane 83 fixed to the surface of the base body 81 on the opening part 76 side by vulcanizing adhesion. The opening part 76 is closed by the contact of the rubber membrane 83 on the opening part 76.
