The influence of cavitation on the thrust characteristics of the oil hydraulic poppet valve was studied experimentally. The state of cavitation occurring was observed carefully and the pressure distributions along the surface of the poppet cone and the valve seat were measured in detail using the half cut model. The comparison of the three kinds of thrust coefficients, obtained by integrating of the pressure distribution on the poppet surface, applying the momentum theory and measuring directly the thrust force with the full shaped model, was made. As the result, the effects of cavitation on the thrust force characteristics and the mechanism of them were made clear. It was also found that especially in case of converging flow valve, the pressure distribution arround the downstream jet was complicated and had large effects on the thrust force characteristics.
