Abstract

See full text

A piston pin assembly is provided including a cylindrical pin body having a hollow interior. A mass is disposed in the hollow interior of the cylindrical pin body and a viscoelastic, plastic, or elastomeric material is disposed in the hollow interior between the mass and the cylindrical pin body. The mass and viscoelastic, plastic, and elastomeric material provides a damper for the piston and piston pin to delay the acceleration of piston lateral motion and stabilize the piston rotation and reduce the noise and friction.
