Abstract
The utility model relates to a carburetor, in particular to a carburetor with a high speed compensation oil circuit device. The utility model adopts the following technical proposal: a carburetor with a high speed compensation oil circuit device comprises a carburetor body and an adjusting screw, an air control shutter axis, an adjusting needle valve, an oil storage chamber and a hollow throat which are arranged on the carburetor body. A passage is arranged between the oil storage chamber and the hollow throat, and an enriched nozzle device is arranged in the fixed device, and a valve seat of the enriched nozzle device is coordinated hermetically with a wall face of the passage. By adopting the proposal above, the hollow throat can be added oil through the enriched nozzle device, thus making the carburetor provide various gas mixtures based on maximum power and maximal revolution. Moreover, the utility model overcomes the deficiency of original technique, and provides a new carburetor with high speed compensation oil circuit device and with reasonable structure, at the same time, the carburetor meets the demands of various gas mixture needed under the condition of maximum power and maximal revolution.
Description
Technical field
The utility model relates to a kind of Carburetor, is meant a kind of with the Carburetor that compensates oil circuit device at a high speed especially.
Background technique
At present, the Carburetor kind of report and appearance is a lot of on the magazine and market, its structure is different, but the effect and the principle of all Carburetors are basic identical, all be that control enters the air of engine and the mixed airflow of fuel, wherein air stream is that when you touched the throttle trigger of transmitter, you were exactly the amount that enters the air of engine in control by the determining positions of throttle.Fuel stream is controlled by spindle.These spindles in fact are a kind of screws, and they have tapered end, stretch into oil circuit from the seat of hole, and fuel flows through the chamber at spindle place, if spindle turns clockwise, it has just reduced circulation area, reduces flow fuel thus.Opposite, if spindle is rotated counterclockwise, circulation area increases, and therefore has more fuel to flow through.Also there are some Carburetors that a plurality of spindles are arranged in addition, except that main spindle, also have low speed needle and middle and high fast spindle.Existing Carburetor, it includes the Carburetor body and is arranged on the intrinsic adjusting screw of Carburetor, throttle plate pin, adjusting spindle, accumulator and trunnion, seal between its accumulator and the trunnion, so having only by regulating spindle, the size of fuel feeding regulates, the mixed gas of the Carburetor of this structure when guaranteeing maximum power during in high speed mixed gas rare partially, cause the maximum speed of motor very high like this, and be difficult to control maximum speed; On the contrary, if mixed gas overrich when the mixed gas when guaranteeing high engine speeds and peak output, power is on the low side, so also inadvisable.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, and the novel band of taking into account the requirement of the different mixed gass that peak output and maximum speed need simultaneously compensates the Carburetor of oil circuit device at a high speed.
Realize above-mentioned purpose, the utility model adopts following technological scheme: a kind of with the Carburetor that compensates oil circuit device at a high speed, include the Carburetor body and be arranged on adjusting screw, throttle plate pin, adjusting spindle, accumulator and trunnion on the Carburetor body, be provided with a passage between described accumulator and the trunnion, this passage internal fixation is provided with the enriching spray nozzle device, and the wall of the valve seat of this enriching spray nozzle device and passage is sealed and matched.Adopt such scheme, can refuel to trunnion by the enriching spray nozzle device, thus different mixed gas can allow Carburetor take into account peak output with maximum speed simultaneously the time.
Further setting of the present utility model is: close accumulator one end that described enriching spray nozzle device includes valve seat, valve seat is provided with the upgrading valve metering-orifice, the other end at valve seat is provided with oil outlet, is provided with valve film and spring between upgrading valve metering-orifice and oil outlet.Utilize this structure to realize the unidirectional logical oil of enriching spray nozzle device, rational in infrastructure, manufacturing is simple.
Of the present utility model further the setting is: close accumulator one end of described valve seat is provided with fixed block, the upgrading valve metering-orifice is opened on this fixed block, inboard at fixed block is provided with boss around the periphery of upgrading valve metering-orifice, this boss one side and valve film cooperate conducting and the disconnection that constitutes oil circuit in the enriching spray nozzle device, between the periphery of the another side of valve film and the oil outlet of valve seat spring is set.Utilize this structure, make the conducting of oil circuit in the enriching spray nozzle device and disconnect very freely the control convenience.
Below in conjunction with accompanying drawing the utility model is done further to be provided with:
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of with the Carburetor that compensates oil circuit device at a high speed, include Carburetor body 1 and be arranged on adjusting screw 2 on the Carburetor body 1, throttle plate pin 3, regulate spindle 4, accumulator 5 and trunnion 6, in the utility model, in order to refuel to trunnion 6, thereby can allow Carburetor can take into account peak output and maximum speed simultaneously, between accumulator 5 and trunnion 6, be provided with a passage 7, these passage 7 internal fixation are provided with oil can only be from the enriching spray nozzle device 8 of accumulator 5 to trunnion 6 one-way flows, the valve seat 81 of this enriching spray nozzle device 8 is sealed and matched with the wall of passage 7, flows and may command from enriching spray nozzle device 8 to guarantee oil.In this use new embodiment, close accumulator 5 one ends that the enriching spray nozzle device 8 that adopts includes valve seat 81, valve seat 81 are provided with upgrading valve metering-orifice 82, the other end at valve seat 81 is provided with oil outlet 83, is provided with valve film 84 and spring 85 between upgrading valve metering-orifice 82 and oil outlet 83.Described valve seat 81 is provided with fixed block 86 near accumulator 5 one ends, and upgrading valve metering-orifice 82 is opened on this fixed block 86, fixed block 86 and valve seat 81 split settings, and then surface of contact between the two is for being sealed and matched, and in the present embodiment, both can be wholely set; Inboard at fixed block 86 is provided with round boss 861 around the periphery of upgrading valve metering-orifice 82, and this boss also can be other shape certainly, as square, triangle.These boss 861 1 sides and valve film 84 cooperate conducting and the disconnection that constitutes oil circuit in the enriching spray nozzle device 8, spring 85 is arranged between the periphery of oil outlet 83 of the another side of valve film 84 and valve seat 81.
