Abstract

　外ガスタイプまたは内ガスタイプのアキュムレータにおいて、ゼロダウン時に液室に閉じ込められた液体および封入ガスが熱膨張したときに発生する圧力差を低減させる機構を備え、もってベローズ内外の圧力差を低減させて、ベローズが異常変形するのを抑制する。この目的達成のため、オイルポートのベローズキャップ側に、バネ手段で支持された可動プレートを設ける。定常作動時、可動プレートはバネ手段に支持されてシールから離間している。ゼロダウン時、可動プレートはベローズキャップに押されてバネ手段を弾性変形させながらシールに接触する。ゼロダウン時液室に閉じ込められた液体および封入ガスが熱膨張したときには、可動プレートはシールに接触したままでベローズキャップが液圧とガス圧とが釣り合う位置まで移動する。
