概要

論文の詳細を見る
In this report the author has made an experimental analysis on the lateral forces, the discharge coefficient, the stability and frequency of a poppet valve. The results are compared with the theoretical analysis reported already in the first report. It is made clear that (1) in order to increase the lateral stability of a poppet valve, it is necessary to make a valve seat ratio larger, to lower a valve lift and to use a working fluid of high viscocity, (2) the theoretical computations show good qualitative agreement with the experiments, and if we adopt the concept of "the effective valve seat ratio", the theoretical computations show good quantitative agreement with the experiments.
