Abstract
A Type II valvetrain and engine brake arrangement includes a brake housing defining a hydraulic circuit and a follower piston chamber and a brake piston chamber. A follower piston in the follower piston chamber is configured to follow a rotating brake cam lobe. A brake piston in the brake piston chamber is in pressure responsive relation with the follower piston to move. A finger follower is disposed so that a brake rod coupled to the brake piston engages the finger follower at least when the brake piston is in an activated position. When the brake piston is the activated position, the finger follower pivots from a first end about a pivot as the finger follower follows a valve cam lobe to effect lifting and seating of a cylinder valve. When the brake piston is activated, the finger follower, at least in part, pivots from the first end about the pivot and the brake rod lifts the cylinder valve and released compression from the engine cylinder.
