The piston ring is a metal elastic ring with large outward expansion deformation, which is assembled into the annular groove corresponding to the cross-section. Reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer circumferential surface of the ring and the cylinder and one side of the ring and the ring groove.
The functions of the piston ring include four functions: sealing, regulating oil (oil control), heat conduction (heat transfer), and guiding (support).
It is a piston ring with superhard wear resistant particle coating and it has characteristics of low abrasiveness rate of piston ring and cylinder liner (the abrasiveness rate of this piston ring is one-third of that of the ordinary ring), and it improved abrasion performance, special coating structure and sound anti-scuffing of the cylinder bore.

Piston rings are widely used in various power machinery, such as steam engines, diesel engines, gasoline engines, compressors, hydraulic machines, etc.
Generally, the piston ring is installed in the ring groove of the piston, and it forms a chamber with the piston, cylinder liner, cylinder head, and other components to do work.
