Importance of rubber shock absorber to starter
Many people do not think that the timing of the launch has something to do with rubber shock absorbers. In fact, they just need to remember that where there is vibration, there can be shock absorbers, but this shock absorber may be a rubber shock absorber, a spring shock absorber, or even other types of shock absorbers. Their existence is obvious, which is to reduce vibration and noise. It can kill two birds with one stone.
Then why should the starter use a rubber damper? It's actually very simple. As just said, where there is vibration, there is a damper. After the starter starts, it will show high frequency vibration and loud sound. At this time, it is necessary to use rubber damper to reduce vibration and noise.
In fact, this is to make people who are operating the initiator warm, and to maintain the initiator free from vibration, which may lead to a reduction in life. Take a car for example. If there is no rubber shock absorber for the car's starter, you will feel very stable and noisy when driving on a flat road. This is the advantage of rubber shock absorber.

6. Classification according to structural characteristics (1) Shut off valve: the closing part moves along the center of the valve seat; (2) Plug valve: the closing part is a plunger or ball, which rotates around its centerline; (3) Gate shape: the closure moves along the center of the vertical valve seat; (4) Swing valve: the closing part rotates around the axis outside the valve seat; (5) Butterfly valve: the disc of the closing part rotates around the axis in the valve seat; (6) Slide valve: the closing piece slides in the direction perpendicular to the channel.
