- 論文の詳細を見る
The thrust force characteristics of oil hydraulic poppet valves are studied experimentally. The thrust force is measured by using two apparatus ; a half cut model and a full shaped model of a poppet valve, with the valve lift X, the seat chamfer length S and the poppet angle 2φ changed. The influence of the change in these three valve factors on the thrust characteristics is made clear by comparison of the thrust coefficients, and the mechanism of the change in the thrust characteristics is also made clear by studying the pressure distributions and the thrust force components within three different region along the poppet surface; the upstream region, the restricted part and the downstream region.
