An actuator piston assembly capable of actuating at least one engine valve, said actuator piston assembly comprising:a piston body having a hollow interior; a screw assembly received within said hollow interior of said piston body; biasing means for biasing said piston body with respect to said screw assembly; a cap assembly located within said hollow interior, wherein said biasing means interacts with said cap assembly and said screw assembly; and securing means located between said piston body and said cap assembly for movably securing said piston body to said screw assembly.
- 2. The actuator piston assembly according to claim 1, wherein said securing means comprises a plurality of balls located between said piston body and said cap assembly for movably securing said piston body to said screw assembly.
- 3. The actuator piston assembly according to claim 2, wherein said securing means further includes a groove located within said piston body, wherein at least a portion of said plurality of balls are located within said groove.
- 4. The actuator piston assembly according to claim 1, wherein said biasing means comprises a spring assembly.
- 5. An actuator piston assembly for use in a rocker arm system, said actuator piston assembly being capable of actuating at least one engine valve, said actuator piston assembly comprising:a piston body having a hollow interior; a screw assembly received within said hollow interior of said piston body; biasing means for biasing said piston body with respect to said screw assembly; a cap assembly located within said hollow interior, wherein said biasing means interacts with said cap assembly and said screw assembly; and securing means located between said piston body and said cap assembly for movably securing said piston body to said screw assembly.
- 6. The actuator piston assembly according to claim 5, wherein said securing means comprises a plurality of balls located between said piston body and said cap assembly for movably securing said piston body to said screw assembly.
- 7. The actuator piston assembly according to claim 6, wherein said securing means further includes a groove located within said piston body, wherein at least a portion of said plurality of balls are located within said groove.
- 8. The actuator piston assembly according to claim 5, wherein said biasing means comprises aspring assembly.
- 9. An actuator piston assembly for use in a rocker arm system, said actuator piston assembly being capable of actuating at least one engine valve during engine braking, said actuator piston assembly comprising:a piston body having a hollow interior; a screw assembly received within said hollow interior of said piston body; biasing means for biasing said piston body with respect to said screw assembly; a cap assembly located within said hollow interior, wherein said biasing means interacts with said cap assembly and said screw assembly; and securing means located between said piston body and said cap assembly for movably securing said piston body to said screw assembly.
- 10. The actuator piston assembly according to claim 9, wherein said securing means comprises a plurality of balls located between said piston body and said cap assembly for movably securing said piston body to said screw assembly.
- 11. The actuator piston assembly according to claim 10, wherein said securing means further includes a groove located within said piston body, wherein at least a portion of said plurality of balls are located within said groove.
- 12. The actuator piston assembly according to claim 9, wherein said biasing means comprises a spring assembly.
- 13. An actuator piston assembly capable of actuating at least one engine valve, said actuator piston assembly comprising:a piston body having a hollow interior; a screw assembly received within said hollow interior of said piston body; biasing means for biasing said piston body with respect to said screw assembly; a cap assembly located within said hollow interior, wherein said biasing means interacts with said cap assembly and said screw assembly; and a plurality of balls located between said piston body and said cap assembly for movably securing said piston body to said screw assembly.
- 14. The actuator piston assembly according to claim 13, wherein at least a portion of said plurality of balls are located within a groove located within said piston body.
- 15. The actuator piston assembly according to claim 13, wherein said biasing means comprises a spring assembly.
