ABSTRACT:
A hydraulic damper is disclosed which has a contraction phase one-way passage way which allows a flow of damping fluid in contraction phase, an extension phase one-way passage way which allows a flow of damping fluid in extension phase, and a valve element in the form of a hollow control rod. The valve element has a neutral position in which both of the contraction phase and extension phase one-way passage ways are open, a first displaced position in which the extension phase one-way passage way is restricted with the contraction phase one-way passage way left open, and a second displaced position in which the contraction phase one-way passage way is restricted with said extension phase one-way passage way left open.
