pistonactuated

Piston actuated refers to a mechanism or device that is powered or controlled by the movement of a piston within a cylinder. This principle is fundamental to many types of engines and hydraulic or pneumatic systems. In an engine, a piston is typically moved by the expansion of gases, often from combustion, which then drives a crankshaft to produce rotational motion. In hydraulic and pneumatic systems, a piston is forced to move by pressurized fluid or air, respectively, allowing for linear actuation to perform work, such as lifting, pushing, or clamping. The sealed environment of the cylinder ensures that the pressure applied to one side of the piston is effectively translated into force and displacement. The design of piston actuated systems can vary greatly, from simple single-acting cylinders that use a spring or external force to return the piston, to complex multi-cylinder engines. Key components include the piston itself, the cylinder bore, seals to prevent leakage, and a connecting rod or other linkage to transfer the motion. The efficiency and power of such systems are often determined by factors like piston diameter, stroke length, operating pressure, and the precision of the manufacturing tolerances.
