  • Single-piece air cylinder for a fluid coupling device
    Patent number: 7430956
    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.

  • SINGLE-PIECE ELECTRO-POLISHED AIR CYLINDER FOR A FLUID COUPLING DEVICE
    Publication number: 20060081123
    Abstract: One advantageous embodiment of the claimed invention is an air cylinder (12) for a pneumatic fan drive system (10). The air cylinder (12) is comprised of a single-piece stamping, which is utilized for covering a piston (22) of the pneumatic fan drive system (10). This single-piece stamping has an e-coating (40) applied thereon for improving a surface finish of the single-piece stamping and inhibiting corrosion of said single-piece stamping.
