In the present study, the numerical simulation has been performed to investigate the flow characteristics of quick coupler. The commercial code, FLUENT, was used for the present study. Design modification of the components was focused on the reduction of the pressure drop for higher efficiency of coupler. For reducing pressure drop of coupler, the shape of guide pine and position of spring were changed properly. The results of CFD showed that the pressure drop has been improved and the performance of modified coupler was superior to that of initial coupler. Therefore, the CFD methods used in the present study could be used to improve the performance of a variety of couplers.
