Abstract

The invention discloses a two-position three-way normally opened type micro fuel oil electromagnetic valve with a buffer mechanism. The electromagnetic valve comprises an armature assembly. The armature assembly comprises an outer armature of a cup body structure. An inner armature is sleeved into the outer armature; a first ejector rod, a third spring and a spring seat are successively sleeved into an inner cavity of the inner armature; a second spring is placed in the inner cavity of the spring seat; the other end of the second spring is in contact with the inner bottom surface of the outerarmature; the spring seat, the third spring, the inner armature and the first ejector rod form an inner armature assembly, wherein the outer armature and the inner armature and the first ejector rod and the inner armature are in clearance fit. The electromagnetic valve has the advantages of being small in size, light in weight, high-temperature-resistant, low in power consumption, high in reliability, long in service life and the like, and solves the problems that an existing electromagnetic valve is large in size, heavy in weight, high in starting energy consumption and the like.

Description

technical field [0001] The invention relates to a two-position, three-position normally open miniature fuel solenoid valve, in particular to a two-position, three-position normally open miniature fuel solenoid valve with a buffer mechanism. Background technique [0002] The fuel adjustment system in the hydraulic system has the advantages of simple structure, high reliability, and good environmental adaptability. Especially in harsh environments such as flammable, explosive, radiation, and vibration, in aviation, ships, and some special fields, fuel oil Regulation systems are widely used. As an important control element of the fuel regulating system, the reliability requirements of the solenoid valve are continuously improved with the development and improvement of the fuel system, and are developing in the direction of high reliability, miniaturization and light weight. However, the traditional two-way three-way fuel solenoid valve commonly used in my country at this stage...
