This paper describes the application of the Finite Element Method to reed type compressor valve simulation. The element chosen allows a significant reduction of degrees of freedom without an impact on the accuracy. It also confers more flexibility to the simulation program, because the valve routine requires only the valve shape and an experimental obtained damping coefficient as input data. Furthermore, leading to better results in terms of displacements, it makes the input data obtained for stress analysis more reliable. These characteristics are also important when simulating valves for a wide range of operating conditions, e.g., variable speed compressors, start-up sequence and the same pump used for different refrigerants. As example of use, a parametric analysis of an actual suction valve is presented.
