Feb 01, 2021Summary. Shock is a life-threatening circulatory disorder that leads to tissue hypoxia and a disturbance in microcirculation.There are many different causes of shock, which are classified into hypovolemic shock (e.g., following massive blood/fluid loss), cardiogenic shock (e.g., as a result of acute heart failure), obstructive shock (e.g., due to cardiac tamponade), and distributive shock (due Failure analysis of shock absorber tubes ScienceDirectShock Absorber Working Principle , Types , FunctionIn addition to its mounting flexibility, mono-tube shocks are a significant component, along with the spring, in supporting vehicle weight. Another difference you may notice is that the mono-tube shock absorber does not have a base valve.
