Embodiment Construction
[0010] The working principles and embodiments of the present invention will be described in detail below in conjunction with the attached structural diagrams, but the details of the structural diagrams and embodiments are not intended to limit the present invention, and any use of the working principles of the present invention should belong to the protection scope of the present invention.
[0011] figure 1 The structure diagram of the pressure-stabilizing relief valve mainly used in the hydraulic control system of automatic transmission provided by the present invention is composed of valve sleeve 1, spool 2, spring 3, and limit plug 4. The spool 2 has a limit convex After being installed in the valve sleeve 1, it can only move in one direction (the opening direction of the valve port). The centering structure of the spring 3 is arranged on the valve core 2 and the limit plug 4, and a limit rod is designed on the limit plug 4 to limit the maximum stroke of the valve core and...
