Study of Valve Motion in Reciprocating Refrigerator Compressors based on the 3-D Fluid–structure Interaction Model

In this paper, valve motion in the refrigerator reciprocating compressor is studied based on a 3-D fluid-structure interaction model. Experiment of the P-V graph was carried out to validate the numerical model. Simulations showed that increased thickness of the valve would finally prolong delayed closure. It seems a little different from the traditional prediction that increased thickness would result in increased strength and advanced closure.
