Piston assembly

My design for piston assembly via SolidWorks. All parts & assembly files are in SolidWorks. A piston is a cylindrical component that moves reciprocally within a cylinder. It's a fundamental part of many engines, pumps, and compressors, where it transforms pressure changes into mechanical motion or vice versa. Typically made of metal, a piston is fitted with rings to create a seal against the cylinder walls.
