Abstract

　シリンダボア２５ｆが弁板吐出ポートに連通する直前にシリンダボア２５ｆと弁板吐出ポートとを連通させる自己圧絞り５２と、シリンダボア２５ｆが弁板吸込ポートとの連通状態を脱した後からシリンダボア２５ｆが自己圧絞り５２に連通するまでの間に、弁板吐出ポートとシリンダボア２５ｆ内とを一時的に連通させる油路４０を設け、該油路４０は、連通時にシリンダボア２５ｆ側の油路内の高圧をシリンダボア２５ｆ内に伝達させるとともに、非連通時にシリンダボア２５ｆ側の油路内の圧を次のシリンダボアとの連通前に弁板吐出ポート側の圧に復旧できる長さを有する。これによって、簡易な構成で、比較的広い回転数領域で脈動を抑止することができる。
