Abstract
A dual-direction piston-based actuator housing assembly has a housing disposed over a hollow cylindrical liner configured to accept within a movable piston. A compression block having a pin engagement hole is disposed adjacent to a proximal end of the liner. A tension strap is disposed over the compression block, the tension strap starting from a first end near the proximal end of the liner, extending around the engagement hole and back to a second end near the proximal end of the liner. An overwind extends over the first and second ends of the tension strap, over the compression block, and over the proximal end of the housing. A tension clip is disposed at the distal end of the liner and embedded within the housing. The housing, tension strap and overwind may be a continuous fiber reinforced plastic composite and the compression block may be a chopped fiber filled thermoplastic composite.
