Abstract: There is set forth herein an actuator having a housing and a piston assembly. The piston assembly can have a piston and a piston rod extending from the piston. In one embodiment, the housing can receive the piston and a portion of the piston rod. The piston assembly can define a piston assembly interior and a fluid reservoir can be located within the piston assembly interior. A chamber region within the interior of the housing can be separated by the piston assembly to define a piston side chamber and rod side chamber. The piston assembly can be moveable so that respective volumes of each of the piston side chamber and the rod side chamber are variable. For operation of the actuator by movement of the piston assembly within the interior of the housing, fluid can be moved between the reservoir and the chamber region.

Abstract translation: 这里阐述了具有壳体和活塞组件的致动器。 活塞组件可以具有从活塞延伸的活塞和活塞杆。 在一个实施例中，壳体可以容纳活塞和活塞杆的一部分。 活塞组件可以限定活塞组件内部，并且流体储存器可以位于活塞组件内部。 壳体内部的室区域可以被活塞组件分开，以限定活塞侧室和杆侧室。 活塞组件可以是可移动的，使得活塞侧室和杆侧室中的每一个的相应体积是可变的。 为了通过活塞组件在壳体内部的运动来操作致动器，流体可以在储存器和腔室区域之间移动。
