Engine valve actuator assembly

A valve actuator assembly comprising:

• a movable engine valve;
• a movable roller finger follower connected to said engine valve;
• a rotatable cam;
• a first intermediate finger follower contacting said roller finger follower;
• a second intermediate finger follower contacting said roller finger follower;
• and
• a first actuator connected to said first intermediate finger follower to move said first intermediate finger follower in either one of a horizontal direction and a vertical direction to position said first intermediate finger follower relative to said cam to move said roller finger follower to position said engine valve for a primary opening of said engine valve at either one of a desired lift and phasing and a second actuator connected to said second intermediate finger follower to move said second intermediate finger follower in either one of a horizontal direction and a vertical direction to position said second intermediate finger follower relative to said cam to move said roller finger follower to position said engine valve for a secondary opening of said engine valve at either one of a desired lift and phasing.

A method of operating a valve actuator assembly for a vehicle comprising:

• providing a movable engine valve;
• providing a movable roller finger follower connected to the engine valve;
• providing a cam and rotating the cam;
• providing a first intermediate finger follower and contacting the roller finger follower;
• providing a second intermediate finger follower and contacting the roller finger follower;
• actuating at least one first actuator operatively cooperating with the first intermediate finger follower, positioning the first intermediate finger follower relative to the cam, and positioning the engine valve at either one of a desired lift and phasing for a primary opening of the engine valve;
• and
• actuating at least one second actuator operatively cooperating with the second intermediate finger follower, positioning the second intermediate finger follower relative to the cam, and positioning the engine valve at either one of a desired lift and phasing for a secondary opening of the engine valve.
