Patent ID: 8651251

Claim:
A regulated dashpot with shock-absorption force controls, for motor vehicles, comprising: at least one flow-regulating system including at least one shock-absorption component for a compression phase and for a decompression phase, a main valve assembly of said shock-absorption component is formed by at least one valve assembly with electrically variable flow resistance, regulated by a regulating valve with variable flow constriction, said flow resistance being continuous for providing continuous damping between soft and hard damping; at least one fixed bypass valve with a non-varying constricted flow cross-section, hydraulically and directly paralleling the flow-regulating system, said fixed bypass valve having a constant opened flow-through cross-section hydraulically in parallel with said regulating valve; wherein, said fixed bypass valve is integratable into said flow-regulating system and has a minimal passage for hydraulic fluid; said fixed bypass valve has a constant non-adjustable flow cross section; and said regulated dashpot further comprises preset pressure-dependent valves for said compression phase and said decompression phase being preset with a hard performance curve, said valves hydraulically paralleling said flow-regulating system and said shock absorption component.
