Abstract

　外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、ゼロダウン時に液室１１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圧力差調整機構２１を有する。前記調整機構２１は、ベローズキャップ８のオイルポート４側にコイルスプリング２３で支持された可動プレート２２を有する。定常作動時、プレート２２はスプリング２３に支持された状態でキャップ８とともに移動し、ゼロダウン時、プレート２２はキャップ８とともに移動してシール１３に接触し、液体および封入ガスの熱膨張時には、プレート２２はシール１３に接触したままでキャップ８が液体圧とガス圧が釣り合う位置までスプリング２３を圧縮しながら移動する。
