ABSTRACT:
A working cylinder for pneumatic or hydraulic pressure media has a piston reciprocable in a cylinder chamber closed at one end. The cylinder and the piston have polygonal cross-sections. The end of the cylinder may be closed by a cylinder cap secured in place by bolts passing through it and threaded in the ends of the cylinder. Polygonal seals are provided between the cylinder caps and the piston and the interior walls of the cylinder. Two opposed walls of the cylinder may be thicker than the outer walls, and provided with through holes for attachment means.
