A rectangle with a piston rod out both ends.
Also known as: Through-rod cylinder symbol, Double ended cylinder
In ISO 1219 fluid power diagrams a double-rod cylinder is drawn with a rod projecting from both ends, giving equal areas and so equal force and speed in both directions.
Denotes a cylinder with a rod at each end, giving equal effective area on both sides of the piston.
Contexts: Technical drawing
Is chosen precisely to remove the force and speed asymmetry that a single-rod double-acting cylinder has.
