Abstract
The utility model discloses an idle speed regulating limiting device type carburetor matched with a general engine used on a generator, a weeding machine, a water pump, etc. The utility model comprises a carburetor body 1, an operating handle 2 of a choke valve, a shaft component 3 of an air throttle, an opening regulating screw 4 of the air throttle, and a mixed gas regulating oil needle 5, wherein a plug sleeve 8 is arranged on the mixed gas regulating oil needle 5 and the plug sleeve is stuck with the mixed gas regulating oil needle 5. The external shape of the plug sleeve 8 is corresponding to the shape of a trough 7 of the carburetor body 1, which leads the plug sleeve not to rotate in the trough. A regulating screw plug 9 of the air throttle is arranged on the opening regulating screw 4 of the air throttle, and the regulating screw plug 9 of the air throttle is stuck with the opening regulating screw 4 of the air throttle. The utility model solves the problem that the idle speed part of an original carburetor can be regulated. The technical states can not be changed. The optimum technical states matched with a general engine can be kept. The strict discharging requirements for an engine can be fully satisfied.
Description
One, technical field
The utility model relates to a kind of Carburetor that general purpose engine mated that is applied to fields such as generator, weeder, suction engine.
Two, background technique
The Carburetor that present general purpose engine is mated, its idling partly is adjustable, this Carburetor before dispatching from the factory according to the good state of the art of Engine Matching the mixed gas of control idling being regulated spindle and the throttle opening adjusting screw is regulated, make Carburetor when engine oil, the ratio of fuel oil and air reaches optimum mixture ratio.But after Carburetor dispatched from the factory, the user can be to its regulated at will, and the matching status of Carburetor will change so, thereby has influenced the performance of motor, causes the engine operation instability, and toxic emission increases.
Three, model utility content
The purpose of this utility model is to provide a kind of idle limit stoper formula Carburetor, and this Carburetor can idling be unadjustable in any case after dispatching from the factory, and remains under the best state of the art.
The purpose of this utility model realizes by following technical solution: a kind of idle limit stoper formula Carburetor, comprise Carburetor body, chock plate Joystick, throttle plate pin parts, throttle opening adjusting screw, mixed gas adjusting spindle, described mixed gas adjusting spindle is provided with the obstruction cover and bonds together, and the profile that should stop up cover is corresponding with the shape of the groove of Carburetor body, makes to stop up to overlap and can not rotate in groove; Described throttle opening adjusting screw is provided with the throttle adjust screw plug and bonds together.
After adopting the utility model structure, because this mixed gas is regulated spindle and is bonded together with the obstruction cover, and stopping up cover can not rotate in the groove of Carburetor body again, throttle opening adjusting screw and throttle adjust screw plug bond together, and the user can't be regulated this spindle and screw, then the idling of Carburetor is also non-adjustable.Therefore, the utility model compared with prior art, its state of the art can not be changed, and can keep the best-of-breed technology state with general purpose engine coupling, meets the strict emission request of motor fully.

Five, embodiment
With reference to Fig. 1, the mixed gas of the adjustable Carburetor of known idling is regulated spindle and can be advanced and can go out.Regulate to the direction of " advancing " as shown in Figure 1 when this spindle, then the mixed gas of Carburetor supply engine is rarer, and the exhaust gas concentration of discharging behind engine combustion is lower; Otherwise, regulate to the direction of " going out " as shown in Figure 1 when this spindle, then the mixed gas of Carburetor supply engine is denseer, and the exhaust gas concentration of discharging behind engine combustion is higher.Its throttle opening adjusting screw also can be advanced to go out, and is used to regulate the idling speed of motor, and this screw is regulated to the direction of " advancing " as shown in Figure 1, and accelerator open degree increases, and the idling of motor is higher.Otherwise this screw is regulated to the direction of " going out " as shown in Figure 1, and accelerator open degree reduces, and the idling of motor is lower.The user in use can regulate this spindle and screw voluntarily, and changing has related parameter, has so just destroyed the optimum Match state of Carburetor and motor.
With reference to Fig. 2 to Fig. 5 as can be known, the utility model idle limit stoper formula Carburetor, comprise Carburetor body 1, chock plate Joystick 2, throttle plate pin parts 3, throttle opening adjusting screw 4, mixed gas adjusting spindle 5, described mixed gas is regulated spindle 5 and is provided with obstruction cover 8 (as Fig. 6, shown in Figure 7) and bonds together (being coated with glue bond shown in the arrow of Fig. 2), and the profile that should stop up cover 8 is corresponding with the shape of the groove 7 of Carburetor body 1, makes to stop up to overlap and can not rotate in groove; Described throttle opening adjusting screw 4 is provided with throttle adjust screw plug 9 (extremely shown in Figure 10 as Fig. 8) and bonds together (being coated with glue bond shown in the arrow of Fig. 2).Wherein throttle plate pin parts 3 are used to control the size of throttle; Mixed gas is regulated on the spindle 5 can have locking spring 6; The profile of stopping up cover 8 can be polygon structure (as Fig. 6, quadrilateral shown in Figure 7), as long as corresponding with the shape of the groove 7 of Carburetor body 1, makes to stop up to overlap to rotate in groove to get final product; Bonding work all is to carry out after the Manufacturing Technology for Carburetors parameter mixes up.
Claims (1)
