7012 are located at the first inside for stretching bulge loop 7011.Wherein, when spool 6 covers corresponding air inlet (such as with dynamic seal 71
Two air inlets 52) when, projection of the corresponding air inlet on first layer 701 is located at first and stretches the stretching bulge loop of bulge loop 7011 and second
Between 7012.It is below the second air inlet 52 with air inlet for example, working as the sealing element 71 on the second valve plate 62 of drive of spool 6
When i.e. second seal 71 covers the second air inlet 52, projection of second air inlet 52 on first layer 701 is located at first and stretches
Bulge loop 7011 and second stretches between bulge loop 7012.In this example, first the stretching bulge loop 7012 of bulge loop 7011 and second is stretched
The two be pressurized when can abundant crust deformation, to be close to 52 place face of the second air inlet.Again because the second air inlet 52 is first
Projection on layer 701 is located at first and stretches between bulge loop 7011 and second stretches bulge loop 7012, so as to further prevent the
Two air inlets, 52 gas leakage.
What needs to be explained here is that：As shown in figure 5, above-mentioned first stretches the stretching of bulge loop 7011 and second bulge loop 7012
Positioned at the inside of first layer 701, i.e., first stretch bulge loop 7011 and second stretch bulge loop 7012 with the edge of first layer 701 it
