Background technology
At present, along with the development of modern science and technology, the application of solenoid is increasingly extensive, relates to each automatic control technology field.It is widely applied in the automatic control systems such as Aero-Space, automobile, naval vessel, petrochemical industry, metallurgy, jumbo.After solenoid energising, its electric magnet can produce magnetic field, and converts electrical energy into magnetic energy, is further converted into mechanical energy.
Electromagnetic force coil is the critical component in gasoline in-cylinder direct-jet (Gasoline Direct Injection, GDI) the requisite executor of system stable operation.Now; owing to environmental pollution is the most serious; energy crisis is more and more fiery, thus automobile uses low stain energy-saving engine to be always the target of government and professional person, therefore reduces the discharge of electromotor, improves its fuel economy and the most just become the task of top priority of current internal combustion engine person.Improve the flame process in combustor and the novel substitute fuel of employing or fuel additive is then the common method solving problem above.As a kind of novel lean combustion mode, GDI engine combines compression-ignited and spark-ignition engine advantage, achieve the lean burn in cylinder by modes such as the air motions in fuel oil inner cylinder direct injection, variable injection timing and master cylinder, make electromotor all have outstanding performance at fuel economy or reducing the aspect such as discharge.
And direct fuel injection system is as the core of gasoline in-cylinder direct fuel-injection engine, the quality of its performance directly affects the performance of electromotor, the exploitation of GDI high-pressure pump is then one of key and difficult point of gasoline direct fuel injection system exploitation, the particularly performance of high-pressure pump electromagnetic valve directly determines the realization of high-pressure pump function, and it is most important on the impact of high-pressure pump performance.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of GDI system high-pressure pump solenoid, dependability and magnetic flux stability are strong, meet the use environmental requirement that automobile is severe, and have reached the function such as fuel-economizing and environmental protection.
The technical scheme provided according to the present invention, described GDI system high-pressure pump solenoid, including case and the skeleton being arranged on casing interior, uniform winding enamel-covered wire on skeleton, in skeleton upper end, flux ring is set, it is characterized in that: arrange plastic package sleeve between described skeleton, flux ring and case, the lateral surface of plastic package sleeve closely cooperates with the medial surface of case, and the medial surface of plastic package sleeve closely cooperates with skeleton and flux ring；The upper end of described plastic package sleeve forms straight cutting set, described skeleton arranges left pin cavity and right pin cavity, left contact pin and right contact pin are set in left pin cavity and right pin cavity, left contact pin and right contact pin are stretched out by straight cutting set, left contact pin is connected with one end of enamel-covered wire, and right contact pin is connected with the other end of enamel-covered wire；Described flux ring is positioned at the upper end open of plastic package sleeve.
Described skeleton outer circumference surface is provided with High-precision spiral wire groove, and enamel-covered wire is around being located on this High-precision spiral wire groove.
Compared with the prior art the present invention has the advantage that present configuration is simple, compact, rationally；Volume is little, low cost, it is adaptable to automatic batch production；Mechanical strength is high, is hardly damaged；Reliable operation, magnetic flux is stable；Electromagnetic response speed is than very fast, and low-temperature-rise, technology has reached domestic and international advanced level.
