Filled to PTFE Nonstandard Piston Ring 

Filled PTFE Nonstandard Piston Ring Lubrication of Round O Flat Gasket is difficult and has been a driving force to improvements in the quality of motor oil. The oil must survive high temperatures and harsh conditions with a high-speed sliding contact. Lubrication is particularly difficult as the rings have an oscillating motion rather than continuous rotation (such as in a bearing journal). At the limits of piston movement, the ring stops and reverses direction. This disrupts the normal oil wedge effect of a hydrodynamic bearing, reducing the effectiveness of the lubrication. Piston Ring is also sprung to increase the contact force and to maintain a close seal. PTFE Flat Gasket is provided by either the stiffness of the ring itself or by a separate spring behind the seal ring. Round O Ring Gasket is important that rings float freely in their grooves within the piston, so that O Ring can stay in contact with the cylinder. Rings binding in the piston, usually due to a build-…
