Variable force engine valve actuator |
摘要 |
An engine valve actuator is provided. The engine valve actuator includes a first piston and a second piston. The second piston is moveably received within the first piston. The engine valve further includes an actuator body that has a bore defining a first stop and a second stop. The first stop is configured to engage the first piston to limit movement of the first piston at a first preselected distance of travel. The second stop is configured to engage the second piston to limit movement of the second piston at a second preselected distance. A valve element is operatively connected to the second piston to move in response to movement of the second piston.
