Abstract
A vortex valving assembly for a hydraulic damper is adaptable for use in both a piston and a cylinder end. A generator plate includes a plurality of upstanding, arcuate vanes for imparting a vortex to passing fluid and directing the fluid to a central opening. A control plate having a plurality of openings is stacked adjacent the generator plate to control the entry and exit of fluid from the control plate during reciprocation of the piston.
