Product Characteristics
Product Function & Operation
The piston ring ensures a complete seal between the piston and cylinder wall, preventing gas and lubricating oil leakage while forming a protective lubricating film to minimize metal-to-metal friction.
Operating Principle
Piston rings significantly reduce friction between the piston and cylinder wall during reciprocating motion. Positioned in grooves at the top and bottom of the piston, they maintain close contact with the cylinder wall to create sealed chambers through their elastic design and precise shape.
Structural Design
Typically composed of multiple interconnected rings, piston rings feature specialized structures including oil rings, oil control rings, and spiral grooves. Each structural component serves distinct functions such as cylinder sealing, heat conduction, and lubrication management.
