Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing.
[0023] Such as Figure 5 As shown, the shock absorber includes a bottom valve seat 1 , a bottom valve body 2 and an oil storage cylinder 5 .
[0024] Such as Figure 4 As shown, the bottom valve seat 1 includes a first conical surface 31, a second conical surface 32, a first step 41 and a second step 42, and the first step 41 and the second step 42 are respectively arranged on the first conical surface. 31 and 32 on the second conical surface.
[0025] The bottom valve seat 1 is a sheet metal part, and the first tapered surface 31, the second tapered surface 32, the first layer of steps 41 and the second layer of steps 42 are on the same axis.
[0026] In order to ensure the coaxiality of the first conical surface 31, the second conical surface 32, the first step 41 and the second step 42, when the bottom valve seat 1 is manufactured, it is necessary to draw out the exce...
