Abstract
Disclosed is a hydraulic damper including a valve housing () having a valve housing bore () disposed in abutting relationship with a bypass insert () of a base valve assembly () for isolating a bypass passage () from a reservoir (). The valve housing () defines a valve housing orifice () extending therethrough to define an orifice plane (P). A valve () is rotatably disposed within the valve housing bore () and defines at least one valve orifice () extending therethrough along the plane (P). The valve () is rotatable between a closed position and an open position to align the valve orifice () and the valve housing orifice (). A working fluid flows serially through the bypass passage (), the valve orifice (), and the open valve housing orifice (). A modulating valve () overlays the valve housing orifice () for variably and incrementally increasing the fluid flow through the aligned orifices () in response to an increase in pressure in the valve housing orifice () above a predetermined pressure.
