摘要： A hydraulic actuator containing a hollow body defining a cylindrical cavity and a rod which is mounted to slide within the body along a sliding axis between two end positions and which is integral with a piston sliding in a sealed manner within the cylindrical cavity in order to define two chambers. The rod defines an interior passage, connecting the two chambers, which has a valve comprising a shut-off member which is returned towards a seat and closes the passage. The rod receives a push member which can move relative to the rod between a position apart from the shut-off member and a position forcing the shut-off member to open. The push member is constrained, when the rod reaches the end of its stroke, by the push member engaging with a portion of the hollow body.

摘要： A hydraulic actuator comprising a hollow body (1, 3) defining a cylindrical cavity and a rod (5) which is mounted to slide within the body along a sliding axis between two end positions and which is integral with a piston sliding in a sealed manner within the cylindrical cavity in order to define two chambers (C1, C2). The rod defines an interior passage, connecting the two chambers, which has a valve (20) comprising a shut-off member (21) which is returned towards a seat (22) and closes the passage. The rod receives a push member (15, 26) which can move relative to the rod between a position apart from the shut-off member (21) and a position forcing the shut-off member to open. The push member is constrained, when the rod reaches the end of its stroke, by the push member engaging with a portion (3) of the hollow body.

摘要翻译： 一种液压致动器，包括限定圆柱形空腔的中空体（1,3）和杆（5），所述杆（5）安装成沿着两个端部位置之间的滑动轴线在所述主体内滑动，并且与以密封方式滑动的活塞成一体 在圆柱形腔内，以限定两个腔室（C1，C2）。 所述杆限定连接两个室的内部通道，所述内部通道具有包括关闭构件（21）的阀（20），所述关闭构件（21）朝向座（22）返回并关闭通道。 杆接收推动构件（15,26），该推动构件能够在远离关闭构件（21）的位置和强制关闭构件打开的位置之间相对于杆移动。 通过推动构件与中空体的一部分（3）接合，当杆到达其行程的末端时，推动构件受到约束。
