Development of a switching roller finger follower for cylinder deactivation in internal combustion engines

A switching rocker arm for engaging a cam, comprising:

• a rocker arm assembly for operative engagement with the cam, the rocker arm assembly comprising:
• a first arm having a first end, a second end, a first and a second side arm, wherein the first arm is an outer arm;
• a second arm disposed between the first and second side arms, having a first end and a second end, wherein the second arm is an inner arm;
• wherein the second arm is pivotably secured adjacent its first end to the first arm adjacent the first end of the first arm;
• an over-travel limiter that limits pivoting motion of the first arm relative to the second arm, wherein the over-travel limiter is pivotally coupled to the outer arm and interacts with the inner arm, and wherein the over-travel limiter comprises a portion of the first end of the first arm;
• and
• a latch that selectively pivotally couples the inner arm to the outer arm.
