Abstract
A single-piece air cylinder ('air cylinder') for a pneumatic fan drive system. The air cylinder is comprised of a single-piece stamping having a stepped tab portion for attaching to a piston rod of the pneumatic fan drive system. The air cylinder has a cylinder portion and a washer portion extending concentrically inward from the cylinder portion. The washer portion defines an aperture and has the stepped tab portion extending into the aperture. This air cylinder has a sufficiently robust construction for resisting fatigue over a significant number of operation cycles. Additionally, the air cylinder has a substantially robust construction for resisting damage associated with dropping or otherwise mishandling the air cylinder.
