This article presents a theoretical and experimental analysis of sealless pistons featuring a special geometry capable of eliminating friction in pneumatic cylinders and valves. Three different piston geometries were investigated: tapered, stepped, and slot-pocket. Performance was evaluated for each ...
Rotary engines, also known as Wankels, use rotors instead of pistons to compress the air and fuel. This creates a turning motion. This design remains exceedingly rare in the industry, but some manufacturers are trying to bring it back. They tend to be smooth and quiet with fewer moving...
Powered by electric motors, these bridges use mechanisms like hydraulic pistons, operating winches, or gearing. While the entire structure of moveable bridges can be quite long, the length of the movable part is usually limited to a few hundred feet due to engineering and cost considerations. The...
Picture yourself sprinting towards the finish line, legs pumping like pistons — that’s the essence of a lying hamstring curl. How To: Sit or lie face down on a curl machine, adjusting the pads to fit your thighs comfortably. Secure your ankles (or knees, depending on the machine) under...
A body portion 15 of a connector head includes an internal bore 15b which may receive any one of a number of pistons 10, 17, 21 suited for opening different forms of cartridge (puncturable or valve). A suitable support 6, 12, 25 for each respective cartridge type may be attached using...

Based on the investigations, it was observed that the maximum temperature distributed was nearly same in all the types of pistons as 1133K which appeared near the combustion area. The thermal stress and total deformation values of the piston was found to be lesser for the flat and dom...
