Movement of the piston within the industrial shock absorber

Up and down movement of the piston within the industrial shock absorber, the shock absorber fluid cavity they repeatedly from one chamber into the other through different pore cavity.In this case internal friction and fluid friction and oil molecules between the cell walls between the form of vibration damping force, making the car shake energy into heat oil, then absorbed by the shock absorber distributor to the atmosphere. When the oil passage section and other factors constant, the relative velocity damping force with the frame and axle (or wheel) between the increase and decrease, and with oil viscosity related.
