The thrust force characteristics of the oil hydraulic poppet value accompanied by cavitation were studied experimentally. Changing the three value factors, the value lift X, the chamfer length of the value seat S and the poppet angle 2φ, the thrust force was measured with two apparatus of the full shaped model and the half cut model of a poppet value. Comparison of the thrust coefficients made clear the influence of change of the three valve factors on the thrust characteristics. And the mechanism that the influence appeared was made clear by measuring the pressure distribution along the poppet surface in detail using the falf cut model and studying the components of the thrust force in three parts of the upper-stream side, the metering restriction part and the down-stream side.
