Claims (1)
される隔室Ｓをシリンダケース１内に設けるとと
もに、シリンダケース１の排油用の油路６内に開
路方向に付勢したポペツト９を設け、隔室Ｓが昇
圧されるにともなつてポペツト９が付勢に抗して
油路６を閉じる方向に変位した時に、シリンダケ
ース１からの排油に絞り抵抗を与える絞り手段を
設けてある油圧シリンダ。 A compartment S whose pressure is increased when the piston 3 approaches the stroke end is provided in the cylinder case 1, and a poppet 9 biased in the opening direction is provided in the oil passage 6 for draining oil of the cylinder case 1. This hydraulic cylinder is provided with a throttling means for applying throttling resistance to the drained oil from the cylinder case 1 when the poppet 9 is displaced in the direction of closing the oil passage 6 against the force as the pressure is increased.
