The plunger 4 is pressed down to block the air hole.
The shuttle valve element 7 is arranged on the inner side of the guide sleeve 6, the guide sleeve 6 is positioned in a cavity which is communicated and vertical to the cavity where the outer side end of the movable iron core 4 is positioned, and the outer side end and the lower end of the guide sleeve 6 are respectively communicated with an air hole. The valve core 7 can block one of the air holes by sliding in the guide sleeve 6.
According to the above structure, during operation, the movable iron core 4 is driven by the coil 2 to perform high-speed adjustment operation, so that the pilot air pressure is adjusted according to the instruction, and the pilot air pressure (input signal of the proportional valve) is controlled by the electric signal, so that the output of the proportional valve can be rapidly changed along with the change of the electric signal.
All the above components are prior art, and those skilled in the art can use any model and existing design that can implement their corresponding functions.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
