摘要： PROBLEM TO BE SOLVED: To provide a low-speed fuel passage in a carburetor, preventing fuel from being stored in an intake passage by improving low-speed fuel blowout and enhancing low-speed fuel atomization.
SOLUTION: This low-speed fuel passage of the carburetor is provided with a bypass passage 37 for communicating the upstream and downstream sides of a throttle valve 5. The bypass passage 37 is composed of: a first passage 37a having an upper end positioned on the valve downstream side of the throttle valve, off-centered in a side direction with respect to the center shaft of the intake passage and opened 38 in the wall surface of the intake passage 3, and a lower end opened in the bottom surface of a carburetor body 2; and a second passage 37b having an upper end opened 39 in the wall surface of the intake passage 3 on the upstream side of the throttle valve 3 and the other end that corresponds to the lower end of the first passage. A pilot outlet is connected to the first passage. Therefore, a low-speed air-fuel mixture blown out from the bypass passage is applied with inertial and forcibly blown out in a swirl state approximately perpendicular to the intake passage, and atomization of low-speed fuel is enhanced.

摘要： PROBLEM TO BE SOLVED: To provide a cable adjusting mechanism which can easily adjust a cable by a single hand in a short time at a low cost. SOLUTION: An insertion hole 22 of a cable holder is made in a cable holder supporting part 20, a nut fitting groove 28 for fitting a nut is cut in the insertion hole, and the nut 30 having a spring ring 32 is fitted to the nut fitting groove. The cable holder is screwed therein by the nut 30, and the friction torque for preventing a free turn is given to the cable holder 21. Since the cable holder is screwed with a predetermined resistance, any nut for fixing the cable holder can be dispensed with, and the cable holder can be easily adjusted by a single hand. In addition, the insertion hole of the cable holder need not be screwed.

摘要： PROBLEM TO BE SOLVED: To provide a diaphragmatic caburetor for preventing the excessive reduction of the air/fuel ratio and the seizure of an engine by preventing a fuel adjusting needle from closing fully with a simple structure. SOLUTION: The needle 21 is engaged with an inner hole 27 of a cylindrical screw body 16. The length of the needle 32 projecting from the screw body 16 is adjusted so that a prescribed opening of a restriction 12 is secured by the needle 21 when the screw body 16 is inserted into the inner hole 27 in the full-closed position. Therefore, the fuel adjusting needle cannot be adjusted fully closed, so that the excessive thin state of the air/fuel ratio and the seizure of the engine are prevented.

摘要： PROBLEM TO BE SOLVED: To provide a carburetor stabilizing fuel flow by making the total length of slow fuel line passage short and reducing the number of joint parts, and improving reliability by reducing icing and salting. SOLUTION: This carburetor is provided with a slow passage guiding fuel to an idle port 25 and a bypass port 26 opening to an upper wall surface of an intake passage 3 from a float chamber 6 below the intake passage 3. The slow passage is connected by a connecting pipe 23 disposed in the upstream side of a main nozzle and crossing the intake passage. Therefore, the total length of the slow fuel line passage is shortened and the number of the joint parts of the passage is reduced, which can stabilize the flow of slow fuel.

摘要： PROBLEM TO BE SOLVED: To rapidly decelerate an engine without generating an engine stall by rapidly closing a throttle valve up to the specified opening, while gradually closing the throttle valve at the specified opening or less in the closing action of the throttle valve. SOLUTION: This accelerating/decelerating device for a carburetor is provided with a pressure chamber 26 communicating with an air bleed chamber 14 of the carburetor, and a diaphragm 25 for increasing/decreasing the volume of the pressure chamber 26. The diaphragm 25 is interlocked to decrease the volume of the pressure chamber 26 in the opening operation of a throttle valve 8 and to increase the volume of the pressure chamber 26 in the closing operation. A plurality of air passages 42, 43 provided with throttle parts 40, 41 are connected to the pressure chamber 26, and a valve mechanism 45 is provided for closing at least one air passage when the throttle valve 8 has a specified opening or less. The inflow of air into the pressure chamber 26 is thereby increased up to the specified opening to rapidly close the throttle valve 8, while the inflow of air into the pressure chamber 26 is reduced at the specified opening or less to gradually close the throttle valve 8.
