    摘要： An exhaust valve rocker arm for an exhaust valve rocker arm assembly operable in a combustion engine drive mode and an engine braking mode, and configured to selectively open first and second exhaust valves, includes a body defining an aperture to receive a rocker shaft such that the body is rotatable about the rocker shaft, a bore defined in the body, and a rotating stepped engine brake capsule disposed in the bore and having a castellation mechanism. The rotating stepped engine brake capsule is movable between a locked, engine brake active position and an unlocked, engine brake inactive position.

    摘要： The invention concerns an internal combustion engine (1) having a camshaft (2) and valves (3), comprising:
    a first rocker arm part (4);
    a second rocker arm part (5), wherein the first rocker arm part (4) and the second rocker arm part (5) are pivotably mounted; and
    a latch (6) for activating a transmission of an actuation motion between the camshaft (2) and at least one valve (3);
    wherein, in a first rotational position, a latch (6) form-fittingly engages with a contact surface (24) of the first rocker arm part (4) such that a valve actuation motion is transmittable from the camshaft (3) of the internal combustion engine (1) via the first rocker arm part (4) and the second rocker arm part (5), and, in a second rotational position of the latch (6), enables a relative movement of the first rocker arm part (4) and the second rocker arm part (5).
