摘要

The circular-cylindrical housing has a center lengthwise axis (10) concentric with a movably positioned aluminum or aluminum alloy piston-rod (5) protruding from the housing with seal. The surface (24) of the piston rod is exposed to compressive tension (25), and is exposed to tractive tension (27) near the center lengthwise axis. One end of the piston rod has a cylindrical pin holding a piston. The second end has a threaded pin holding a fixture element.
