抄録

In the fourth report we studied the relations between valve-lift, discharge, lifting-force and angle of issuing-jet for the nine kinds of flat-seated valve, all of which discharge water freely in the air. From the experimental data thus obtained non-dimensional discharge q0 and lifting-force p0 are computed and expressed as functions of opening-ratio l/d0 or diametral-ratio d/d0, where l stands for valve-lift, d for valve-diameter and d0 for valve-port diameter. These experimental formulae give fundamental values for discharge and lifting-force of disc valve and could be referred to as standard formulae in the research on disc valves of any kinds.
