Piston for hydraulic shock absorbers has piston washers that provide resistance during operation and fix valves to piston

摘要

Two piston washers of a high resistance fasten a central core fabricated from reinforced polymeric material of low friction. Traction and compression chambers communicate through orifices in the core and the piston washers. The core guides a long piston rod into an inner tube of a shock absorber. The piston washers fix valves to a piston and provide resistance during operation.
