Abstract

The invention discloses a normally-open pulse modulation type rapid electromagnetic valve. The electromagnetic valve comprises a shell; a coil pressing block and a coil assembly are placed in the shell from left to right; a pole shoe assembly is placed in the coil pressing block and the coil assembly; two mounting cavities are formed in the left side and the right side of the interior of the poleshoe assembly separately and communicate with each other through an ejector rod cavity; a locking structure and an armature are arranged in the left mounting cavity from left to right; the armature isconnected to an ejector rod penetrating into the ejector rod cavity; the other end of the ejector rod is connected to a baffle located in the right mounting cavity; a nozzle is further arranged in the part, on the right side of the baffle, of the right mounting cavity; an oil inlet channel is formed in the nozzle; an oil outlet communicating with the outside is further formed in the part, on theleft side of the nozzle, of the right mounting cavity; and a baffle spring is arranged between the baffle and the nozzle. The electromagnetic valve has the advantages that the overall structural design is reasonable, the design of the locking structure is ingenious, the sealing performance is reliable, the flow control precision is high, the response speed is high, the weight is light, and the like.

Description

technical field [0001] The invention relates to an electromagnetic valve, in particular to a normally open pulse modulation fast electromagnetic valve. Background technique [0002] With the rapid development of electro-hydraulic integrated control technology, traditional hydraulic mechanical fuel control is gradually replaced by electro-hydraulic control. The continuous improvement of the development of the system directly plays a vital role in the overall performance of the entire engine. [0003] However, the current electro-hydraulic control solenoid valve has a cumbersome structure, large volume, heavy mass, unreliable sealing, poor flow control accuracy, and slow response speed. Contents of the invention [0004] The purpose of the present invention is to provide a normally open pulse modulation fast electromagnetic valve. The solenoid valve has the advantages of reasonable overall structure design, ingenious locking structure design, reliable sealing, high flow co...
