Claims (1)
ぞれのポートを内周に開口させたボデイと、この
ボデイの内周に嵌合させた流路切換用のスプール
とを具備してなり、前記ボデイの内周における高
圧が作用する両ポートに対向する部位にそれぞれ
圧力ポケツトを設けるとともに、前記スプールに
は少なくともポンプ側流路とシリンダ側流路の遮
閉時に各圧力ポケツトを対向するポートにそれぞ

徴とする手動方向切換弁。 The body includes a body in which ports constituting a pump-side flow path and a cylinder-side flow path are opened on the inner periphery, and a spool for switching the flow path fitted into the inner periphery of the body. Pressure pockets are provided on the inner periphery of the spool at locations facing both ports on which high pressure acts, and the spool is provided with pressure pockets that communicate with the opposing ports at least when the pump-side flow path and the cylinder-side flow path are closed. A manual directional control valve characterized in that it is provided with respective pressure impulse paths.
