Abstract
The utility model is particularly related to a kind of anti-vibration Carburetor, be provided with float in the sediment bowl, float can move up and down and transmission closes or open oil inlet passage for the thimble rod of needle-valve, and the float below is provided with the spacing block body that the needle-valve that can make on the oil inlet passage is not exclusively opened all the time.In the utility model because float lower end is provided with limiting block, so oil inlet passage is also just not exclusively opened when float moves to bottom, can keep the balance of fuel delivery and demand, guarantee the abundant burning of mixed gas, reduce exhaust gas discharging, reduce atmospheric pollution.
Description
Technical field
The utility model relates to a kind of Carburetor, particularly a kind of anti-vibration Carburetor.
Background technique
The small-sized single cylinder petrol engine uses to such an extent that Carburetor has two kinds at present: a kind of is diaphragm type, and a kind of is float type.Diaphragm carburetor formula fuel oil directly contacts with air, produces fuel-air mixture and enters cylinder liner.Because the diaphragm carburetor channel cross-sectional area is less, adds that air is unholiness, passage easily stops up.Especially petrol engine is under many rugged environment of drifting along, and this shortcoming is more obvious.Float carburettor is after oil enters sediment bowl, is sucked trunnion generation mixed gas by air and enters cylinder liner, has overcome the susceptible to plugging defective of diaphragm carburetor passage.But this petrol engine is applicable to more stably and works under the condition.If be used for the up-down vibration frequency about 600 times/minute, amplitude are greater than the vibrating machine of 40mm, be not subjected to level control when float up-down vibration frequency and amplitude are excessive, the feasible needle-valve that is in transmission connection with float is in the state of opening oil-feed all the time, can't control the switch of needle-valve by liquid level, it is uncontrollable oil mass to occur, be fuel delivery greater than the actual demand amount, cause the waste of fuel oil.
The model utility content
The utility model purpose is to provide a kind of Carburetor of anti-vibration.
To achieve these goals, the utility model adopts following technological scheme: a kind of anti-vibration Carburetor, be provided with float in the sediment bowl, float can move up and down and transmission closes or open oil inlet passage for the thimble rod of needle-valve, and the float below is provided with the spacing block body that the needle-valve that can make on the oil inlet passage is not exclusively opened all the time.
The filler opening diameter of described oil inlet passage is 0.5mm～2mm.
The filler opening diameter of described oil inlet passage is preferably 1.2mm.
On the described carbureter body with sediment bowl in the suction port that is connected be provided with one-way valve.
Described float above and below is equipped with limiting block, and control float stroke up and down is 5mm～15mm.
Described float above and below is equipped with limiting block, and control float stroke up and down is 10mm.
Existing Carburetor is in the vibration working environment, float can move up and down, when surpassing certain frequency and amplitude, switch will be malfunctioning, promptly be equivalent to oil inlet passage and be in standard-sized sheet all the time, but in the utility model because float lower end is provided with limiting block, so oil inlet passage is also just not exclusively opened when float moves to bottom, and the restriction of the filler opening diameter of oil inlet passage also controlled oil inlet quantity, the balance that can keep fuel delivery and demand, guarantee the abundant burning of mixed gas, reduce exhaust gas discharging, reduce atmospheric pollution.The oil spill of sediment bowl went out when suction port was provided with one-way valve and can effectively prevents to vibrate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment: anti-vibration Carburetor as shown in Figure 1, be provided with float 6 in the sediment bowl 9, one side of float 6 is connected with connecting rod 10, an other end of connecting rod 10 is hinged on the housing 2 by bearing pin 5, on the connecting rod between float 6 and the articulating point 10, be abutted against the thimble rod 14 that needle-valve 3 is arranged, float 6 transmission that can move up and down closes or opens oil inlet passage for thimble rod 14, float 6 belows are provided with lower limit block body 7, needle-valve 3 when float 6 moves downward transmission to thimble rod 14 on the oil inlet passage is not exclusively opened all the time, and thimble rod 14 lower ends are connected with needle-valve 3 lower end elasticity by spring 4.Sediment bowl 9 inner bottom parts of Carburetor are provided with oil outlet 11.
Filler opening 12 diameters of oil inlet passage are 1.2mm in the present embodiment, and float 6 above and belows are respectively equipped with upper limit block body 8 and lower limit block body 7, control float about in the of 6 stroke be 10mm.
On the carbureter body 2 with sediment bowl 9 in the inlet hole 13 that is connected be provided with one-way valve 15, can prevent effectively that the gasoline in the sediment bowl 9 overflow in the vibration processes.
The utility model is specially adapted to vibrate under the stronger working environment, for example can be used for vibratory rammer, vibratory tamper, when under the stronger working environment of this vibration, working, because float 6 lower ends are provided with spacing block body 7, so the needle-valve 3 of oil inlet passage is also just not exclusively opened when float 6 moves to bottom, and the restriction of filler opening 12 diameters of oil inlet passage also controlled oil inlet quantity, the balance that can keep fuel delivery and demand, guarantee the abundant burning of mixed gas, reduce exhaust gas discharging, reduce atmospheric pollution, and stable performance, reliable.
Claims (6)
