The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiments and the drawings, but should not limit protection domain of the present utility model with this.
With reference to figure 3 and Fig. 4, the two-chamber servo-unit of present embodiment comprises: dividing plate 31, front case 32, rear housing 33, seal ring 34, orienting sleeve 35, stop sleeve 36, pipe link 37.
Wherein, the outer rim of dividing plate 31 is fixed between front case 32 and the rear housing 33, is provided with preceding atmosphere chamber between front case 32 and the dividing plate 31, has back atmosphere chamber between rear housing 33 and the dividing plate 31.The inner edge of dividing plate 31 is by seal ring 34 and orienting sleeve 35 slipper seals.
Comprise the chamber, initial vacuum in the front case 32, realize power-assisted by the pressure reduction between atmosphere and the vacuum.
Have mounting hole on rear housing 33 and the dividing plate 31, be provided with stop sleeve 36 in the mounting hole, preceding atmosphere chamber can be identical by the endoporus of stop sleeve 36 with the back atmosphere chamber.As a nonrestrictive example, the material of stop sleeve 36 for example can be plastics.
