摘要：
A variable valve actuation system to actuate and control the seating velocity of an internal combustion engine valve is disclosed. The system comprises: a housing having a bore formed therein an outer piston slidably disposed in the bore, the outer piston having an orifice formed therein a catch piston slidably disposed in the outer piston and an cone-shaped extension extending from the inner piston, wherein the cone-shaped extension is adapted to provide a variable flow area through the outer piston orifice to provide improved engine valve seating.
