Piston Head

The following model is a 3D CAD model of an ordinary Piston head. A Piston is a a disc or short cylinder fitting closely within a tube that moves up and down against a liquid or gas, used in an internal combustion engine to derive motion, or in a pump to impart motion. The piston head is a disc or cylindrical part that forms the end of a piston, which is attached to the piston rod.
