The commonly used servo motor single pump has a relatively complex structure, relatively low fuel pressure, and the highest short-circuit fuel pressure does not exceed 8 bar (bar). At the same time, the control of this kind of fuel pump is relatively complicated, so there is an urgent need for a light weight, high pressure, structure. Simple and reliable fuel pump

Abstract
The present invention proposes a moving-coil high-frequency booster pump, which includes an oil inlet, an oil cylinder, a piston rod, a piston, a magnetically conductive cover, a pump body, a permanent magnet, an oil outlet, a first spring, a second spring, a power cord, Winding frame, coil, bolt, one-way valve, oil return hole, oil cylinder and pump body are connected by bolts, magnetically conductive cover is set at the port of pump body, magnetically conductive cover and pump body are connected by thread, and oil cylinder is provided with One-way valve, oil inlet, piston and piston rod, oil return hole is set on the magnetic conduction cover, the one-way valve communicates with the pump chamber through the oil return hole on the magnetic conduction cover, the first spring is sleeved in the pump chamber On the piston rod, one end of the first spring is connected to the winding frame, one end of the second spring is connected to the winding frame, and the other end is connected to the bottom of the pump body. The permanent magnet is arranged on the inner wall of the pump body, and the coil is wound on the winding frame. The moving-coil high-frequency booster pump of the present invention adopts the linear electromagnetic drive mode, has simple structure, light weight, convenient control, strong driving ability, and can generate higher pressure.
Description
technical field [0001] The invention relates to a fuel boosting machine in an engine, in particular to a moving-coil high-frequency boosting pump. Background technique [0002] The fuel injection system of the engine has a great influence on the performance of the engine. The fuel pressure directly affects the fuel atomization characteristics of the engine. Especially when the aviation two-stroke engine burns medium oil, the atomization is relatively difficult and requires a higher pressure. At the same time, the fuel pump is required to have a relatively simple structure to ensure the power-to-weight ratio and reliability of the engine. The commonly used servo motor single pump has a relatively complex structure, relatively low fuel pressure, and the highest short-circuit fuel pressure does not exceed 8 bar (bar). At the same time, the control of this fuel pump is relatively complicated, so there is an urgent need for a light weight, high pressure, structure. Simple and re...
