A fluid power actuator includes a fluid power actuator housing, a piston assembly, and a screw assembly. The piston assembly is constructed and arranged to move relative to the fluid power actuator housing in response to changes in fluid pressure within the fluid power actuator housing. The screw assembly couples with the fluid power actuator housing and the piston assembly. The screw assembly is constructed and arranged to control movement of the piston assembly relative to the fluid power actuator housing. Such a fluid power actuator is well-suited for various applications such as in loading equipment which is involved in high precision munitions loading, among others.

Fluid power actuator utilizing a screw assembly

A fluid power actuator includes a housing, a piston rod assembly, and a screw and nut assembly. The housing includes a cylinder, a blind end cap, rod end cap, and mounting provisions. The piston rod assembly connects to an external load and is constructed and arranged to move relative to the fluid power actuator housing in response to changes in fluid pressure within the cylinder. The screw and nut assembly couples with the housing and the piston rod assembly. The screw and nut assembly is constructed and arranged to control movement of the piston rod assembly relative to the housing using a motor or a brake. Such a fluid power actuator provides precision positioning, is self-locking on loss of power, and allows back-up manual operation, making it well-suited for various material handling applications such as precision munitions loading, among others.
