Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] see figure 1 , according to the oil volume regulating device of the present invention, comprising: bellows 10, has bellows cavity, and gas is contained in bellows cavity; The carburetor 30 is provided with an oil supply valve 31 and a valve hole 32 communicating with the oil supply valve 31 , and the oil needle 20 can be movably inserted into the valve hole 32 and matched with the oil supply valve 31 . With the change of the working height of the engine, the bellows 10 is deformed due to the change of atmospheric pressure, and the oil needle 30 moves correspondingly with the deformation of the bellows 10, so that the size of the valve hole 32 of the carburetor can be automatically adjusted to further control The amount of fuel supplied makes...

Abstract

The invention discloses a device for adjusting oil quantity. The device for adjusting the oil quantity comprises capsules, an oil needle, and a carburetor; a cavity is formed in each capsule; air is accommodated in the cavity of each capsule; the oil needle is connected with the capsules, and moves along with the expansion and contraction of the capsules; the carburetor is provided with an oil supply valve and a valve hole which is communicated with the oil supply valve; and the oil needle can be movably inserted into the valve hole and is matched with the oil supply valve. Along with the change of the working height of an engine, the capsules are deformed due to the change of atmospheric pressure, and the oil needle does corresponding movement along with the deformation of the capsules, so that the size of the valve hole of the carburetor can be adjusted automatically, the oil supply quantity is controlled further, the air-fuel ratio of oil and gas mixture sprayed from an oil nozzle is reasonable, the reducing amplitude of power of the engine can be reduced, and the oil is saved.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to an oil quantity regulating device. Background technique [0002] The aviation piston engine basically uses a carburetor to supply fuel. The function of the carburetor is to supply the fuel required for the engine to work, and to ensure that the fuel is mixed with air before entering the cylinder combustion chamber, and becomes a mixture with an appropriate mixing ratio (air-fuel ratio) and good atomization. . [0003] When the engine is used on a plateau or high altitude, due to the reduction of atmospheric pressure and air density, the amount of air entering the engine cylinder is reduced. If the fuel supply on the ground is still maintained at this time, the mixture will be too rich and the mixture in the cylinder cannot be guaranteed. The normal combustion of gas reduces the engine power. In order to keep the mixing ratio of the mixture in the cylinder unchanged, it is necessary ...
