변동 배유 오리피스를 갖는 노즐/볼형 서보밸브의 성능 개선
Performance Improvement of a Nozzle/Ball Type Servovalve with Variant Drain Orifice
초록
This paper presents the performance improvement of a Nozzle/Ball type servovalve with variant drain orifice. First of all, the configuration of the novel servovalve is proposed. Then, the static characteristics are investigated under blocked load condition, and its dynamic characteristics are analyzed by using the linearized flow-pressure relationship. Finally, the performance at the null condition of the proposed servovalve is numerically evaluated through the comparison study with the convention at counterparts.
