Stiction is a common phenomenon observed in day to day life. It also plays an important role in determining the dynamics and reliability of reciprocating compressor valves. However, researchers in the field of compressor technology have paid very little attention for assessing its effects, let alone for understanding the basic mechanisms responsible for its occurrence. Fortunately or unfortunately it is also a problem of serious concern in magnetic recording devices, and researchers in the area of tribology have done comparatively detailed studies for understanding the same. Those studies have blamed molecular attraction, surface tension, viscous forces and micro capillary evacuation as the underlying causes for this phenomenon. This experimental investigation concentrated mainly on identifying the dominant parameters and understanding the way they influence valve stiction. Experiments were conducted to quantify stiction in the case of a compressor valve, which was later modified and shown to reduce its effect.
