Pilot valve structure

The utility model provides a pilot valve structure which comprises a pilot valve part (200) and an electromagnetic valve part (300) used for controlling the working state of the pilot valve part (200), and due to the fact that a piston assembly with a reset function is used in a three-position electromagnetic slide valve, the functions of a traditional piston and a reset spring are integrated on the piston assembly. According to the three-position valve, the positions of the three sliding valve cores of a traditional three-position valve can be switched only through cooperation of the piston assembly and the pre-flow-guiding path, the size of the pilot structure and the size of the traditional pilot structure are not obviously changed, and therefore the size of the sliding valve in the length direction is greatly reduced. Beneficial effects of a specific implementation means are referred to an embodiment part. 本实用新型提供了一种先导阀结构,其包括先导阀部(200)和用于控制先导阀部(200)工作状态的电磁阀部(300)，由于在三位电磁滑阀内使用了具有复位功能的活塞组件，将传统的活塞和回复弹簧的功能集成在了
