摘要： PROBLEM TO BE SOLVED: To provide a carburetor capable of supplying appropriate quantity of fuel for start at a time of cold engine.
SOLUTION: The carburetor 1 is provided with an intake air flow path 21 distributing intake air to an engine, a fuel storage part 22 storing fuel from the fuel tank, a fuel supply flow path 30 for start supplying fuel for start from the fuel storage part 22 to the intake air flow path 21, and a solenoid valve 3 provided in a middle of the fuel supply flow path 30 for start. The fuel supply flow path 30 for start between a fuel intake part 31 and the intake air flow path 21 is formed in a straight line shape. Consequently, pressure loss of fuel between the fuel intake part 31 and the intake air flow path 21 is suppressed, and the carburetor 1 can easily draws out fuel to the intake air flow path 21 by negative pressure generated in the intake air flow path 21 without retention of fuel. Since appropriate quantity of fuel for start can be supplied at a time of cold engine, startability of the engine can be secured.

摘要： PROBLEM TO BE SOLVED: To provide a rotating throttle valve carburetor reduced in the number of parts and facilitating high precise assembly.
SOLUTION: A carburetor element 1 is provided with a rotating valve element holding hole 5 to rotatably receive a rotating valve element 3a of a rotating valve body 3; and a bearing part 1b axially supporting an outward protruding shaft 3c coaxially mounted on a rotating valve body so as to combine an operating lever 6. The parts are simultaneously molded through casting emission, and machined for formation. Coaxially processing of a rotating valve element holding hole and a bearing part is facilitated, and high precise centering is facilitated. Further, since a cover body being a different member is not needed, improvement of assembling ability and reduction of an assembly cost can be promoted through reduction of the number of assembling works and a cut of the number of parts.

摘要： PROBLEM TO BE SOLVED: To provide an accelerator for a carburator having a simple structure without using linkage which is not drastically increased in size, for interlocking with a throttle valve and operating a piston type accelerator pump.
SOLUTION: A cam 33 which is arc-shaped with a throttle valve shaft 8 as the center and having a cam face 33A facing an carburetor main body 1 is provided on the lower surface of a throttle valve lever 10, and the accelerator pump 25 is positioned in parallel with the throttle valve shaft 8 and the upper end of a piston rod 28 is made to contact the cam face 33A. The cam 33 pushes down the piston rod 28 accompanying turning of the throttle valve lever 10 in the throttle valve opening direction, and acceleration fuel of a pump chamber 29 is fed to a suction passage 2.

摘要： PROBLEM TO BE SOLVED: To enable to install a rotary throttle valve type carburetor in a narrow location by making the overall height thereof shorter by reducing height dimensions of a carburetor body and a throttle valve.
SOLUTION: A wall body 31 along an inner side circumference surface 3A of a valve hole 3 is formed projectingly upward on an outer side circumference edge part facing to a suction air passage 2 at an idling position of the throttle valve 4 to secure tightness in idling. A dent 32 in which the wall body 31 is fitted at an open position of the throttle valve 4 is provided on a cover body 12 closing a valve hole 3 to make it unnecessary to secure height of the valve hole in which the wall body 31 can rise. Consequently, height dimensions of the carburetor body 1 and the throttle valve 4 can be shortened.

摘要： PROBLEM TO BE SOLVED: To provide a rotary throttle valve type carburetor with a fuel increasing mechanism easily operated, easily readjustable and capable of lifting a throttle valve lever in an idle position to supply an optimum highly-rich mixture.
SOLUTION: A lifting member 28 is pressed with the finger to advance toward the throttle valve lever 8 in the idle position. A locking part 36 of an upper piece 34 of a tip part split in to two is engaged with an engaging part 45 of the throttle valve lever 8, and the throttle valve lever 8 is placed on an upper face 34A of the upper piece 34. An adjusting screw 43 is screwed into an internal threaded hole 41 to bend the upper piece 34 upward. The throttle valve lever 8 is thereby lifted to enlarge the open area of a nozzle hole by an integrally lifted measuring needle. A required and optional fuel increase can be attained by the bent degree of the upper piece 34 corresponding to screwing of the adjusting screw 43.

摘要： PROBLEM TO BE SOLVED: To facilitate re-assembling of a throttle valve in an accelerator operating a piston of an acceleration pump by a cam formed on the throttle valve.
SOLUTION: A cam groove 33 is formed on the throttle valve 4 so as to open the bottom surface. An engagement projection 29 projected on the piston 27 of the acceleration pump 25 is engaged into the cam groove 33. The piston 27 is linearly reciprocated according only to the cam groove 33. When the throttle valve is drawn out, the piston 27 stops at a position as before drawing out. When the throttle valve 4 is re-assembled, the engagement projection 29 is engaged into the cam groove as it is. Thereby, it is not needed that the acceleration pump is disassembled, or that the dimensional relation is strictly set in order to maintain stopping of the piston 27.
