  • Valve actuation system with valve seating control
    Patent number: 8453613
    Abstract: 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.
    Type: Grant

  • Self adjusting valve catch with valve seating control
    Patent number: 8079338
    Abstract: 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, said outer piston having an internal hydraulic passage, an internal chamber defined by an outer piston side wall, and an internal orifice connecting the internal hydraulic passage and the internal chamber; a catch piston slidably disposed in the outer piston; and a 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.

  • Variable valve actuation and engine braking
    Patent number: 7500466
    Abstract: Systems and methods of actuating two engine valves associated with a common engine cylinder using one or more lost motion systems and one or more control valves are disclosed. The control valves are capable of selectively trapping hydraulic fluid in the lost motion systems for auxiliary engine valve actuations and selectively releasing the hydraulic fluid to default to cam controlled valve seating of the engine valves. The systems may provide a combination of main exhaust, compression release, exhaust gas recirculation and early exhaust valve opening in preferred embodiments.
