Abstract
The utility model relates to a membrane engine carburettor which belongs to the improvement on an oil sucking device of the carburettor. The utility model comprises a body, an oil storing chamber (2), an oil sucking chamber (1) and an oil injection device, wherein an oil sucking membrane (3) is arranged in the oil sucking chamber (1) and is contacted with one end of a lever rock arm (5) hinged with a fulcrum pin shaft (4), and the other end of the lever rock arm (5) is provided with a needle valve matched with an oil sucking passage. The membrane engine carburettor designed according to the theme of the utility model overcomes the defect that the carburettor can not be optionally inclined because the original oil sucking chamber uses a float to supply oil so that the installation is convenient and the utility model can normally work as usual after inclined at random.
Description
The utility model relates to the improvement invention of engine and carburetor Oil sucking device.
In the prior art, if carburetor main closure or plunger type carburetor that domestic general purpose engine adopts, its oil-feed system all adopts the mode of structure of float needle valve, and this structure mainly is made of needle-valve Cuo, needle-valve, float, float pin.Before the oil-feed, float is because gravity descends, and needle-valve will be opened, and when fuel oil injection float chamber, fuel oil will produce to buoyancy float, and along with increasing gradually of fuel oil, buoyancy also will increase gradually, till directly only needle-valve is closed.The shortcoming of this structure be exactly this kind Carburetor in use, can only in certain angular range, could work, otherwise Carburetor will be owing to full oil can't proper functioning, the use of limitation Carburetor has brought certain difficulty to installation and maintenance.
At the defective that prior art exists, the utility model aims to provide the indoor Carburetor that Lever type diaphragm Oil sucking device is set of a kind of oil suction, to reach the purpose that Carburetor when mounted can bigger inclination can both be worked.
Another purpose of the utility model, Carburetor can be installed in Anywhere all proper functioning.
The utility model is a purpose again, and the Carburetor production technology is simplified, cost of production reduces.
The utility model is realized as follows: comprise body, accumulator, oil suction chamber, fueling injection equipment, the indoor oil suction diaphragm that is provided with of described oil suction, oil suction diaphragm one side container is communicated in atmosphere, fulcrum pin axle is set on the opposite side container wall is hinged with the lever rocking arm, lever rocking arm one end is provided with needle-valve and cooperates with the oil suction road, the other end contact oil suction diaphragm; On the described oil suction diaphragm axle is set, this axle contacts with the lever rocking arm the other end; The other end of described lever rocking arm sets Returnning spring; Described oil suction chamber is communicated in the elasticity lubricating cup, and this elasticity lubricating cup is communicated in return tube, and is equipped with valve core, and this valve core is installed in the oil return mouth of pipe, offers a hole and communicates with return tube, and the valve wing covers the passway that the elasticity lubricating cup communicates with the oil suction chamber; Described fueling injection equipment main jet pipe, main metering pin is formed, and offers the triangle spout on the main jet pipe pipe arm.
Diaphragm type engine and carburetor by the novel theme design of this reality, the carburetion air chamber structure is simple, after installing oil pumping system additional, Carburetor position is is anywhere installed and used, easy for installation, overcome traditional Carburetor because full oil can't be worked, and volume is little, in light weight, cost of production can reduce significantly.
The utility model has following accompanying drawing
Fig. 1 the utility model diaphragm carburetor principle schematic
Description of drawings the utility model schematic diagram, below in conjunction with the further smooth embodiment of crossing of accompanying drawing, comprise body, accumulator is provided with the oil suction diaphragm in (2), diaphragm one side cavity and pump oil gas road, engine intake communicates, the oil storage of opposite side cavity communicates with oil inlet pipe, oil suction diaphragm (3) is set in the oil suction chamber (1), oil suction diaphragm (3) one side containers are communicated in atmosphere, and the oil suction of opposite side container is provided with fulcrum pin axle (4) on its container wall, hinged with it is lever rocking arm (5), lever rocking arm (5) one ends are provided with needle-valve (6) and cooperate with the oil suction road, the axle (7) of the other end contact oil suction diaphragm (3), and this end sets Returnning spring.It is big which generation moment Returnning spring and axle (7) are provided with in the other direction, just determines the needle valve switch situation.Described oil suction chamber (1) is communicated in this elasticity lubricating cup (8) of elasticity lubricating cup (8) and is communicated with return tube, and be equipped with valve core (9), elasticity lubricating cup (8) is when mainly being engine start, by extruding lubricating cup (8) air in the lubricating cup (8) is discharged by return tube, pressure reduces in the lubricating cup, the pressure of oil suction chamber is pushed valve core open, and causes the oil suction chamber pressure to reduce, and oil suction chamber (1) sucks oil and proper functioning.Valve core adopts the fluosilicic rubber material to make, and offers a hole and communicates with return tube, and during the lubricating cup extruding, open in the silk hole, at ordinary times silk hole closure.It mainly is to guarantee that Carburetor is installed in any one angle or inclination can both proper functioning that oil pumping system is provided with.
Described fueling injection equipment is cooperated by main jet Guan Yuzhu metering pin piston type and forms, and offers the triangle spout on the main jet tube wall, and the structure of main metering pin adopts cylindrical, and purpose is to reduce manufacture cost, has improved the conformity of part processing.And the main jet pipe of traditional Carburetor adopts machining to form, and main metering pin adopts conical, the manufacture cost height, and conformity is difficult for guaranteeing.
