Circumferential Groove in Cylinder of Piston Machines
Researchers at Purdue University have developed a novel approach to prevent metal-to-metal contact in pistons in the event of insufficient hydrodynamic load carrying ability of the fluid film between the piston and cylinder through the utilization of hydrostatically balanced areas. Subsequently, this technology equips the design of swash-plate type machines for high pressure, utilizing low-viscosity fluids, like water. The technology helps increase the load-carrying capacity of the fluid film between the piston and cylinder due to additional hydrostatic bearing capacity, which helps prevent metal-to-metal contact.
