Abstract
A dual body rocker arm comprising an outer arm, an inner arm, a substantially cylindrical pivot axle, a pivot foot and a first and second pivot foot retaining ring. The inner arm is disposed between side arms of the outer arm. The pivot axle is mounted to both the inner and outer arm. The pivot foot has a cylindrical axle interfacing surface and a valve tip interface. Retaining rings mount the pivot foot to the axle, allowing partial rotation of the pivot foot about the axle. Interfering protrusions on the retaining rings limit the range of motion of the pivot foot. A pivot foot having at least one interfering block is configured to restrict motion of the pivot foot by interfering with at least one interfering tab.

A dual body rocker arm comprising:
- a first end, a second end, an outer arm, an inner arm, a substantially cylindrical pivot axle, a pivot foot, and a first and second pivot foot retaining ring;
- the outer arm having a first and second outer side arm extending from the first end to the second end, and outer pivot axle apertures disposed adjacent the first end and configured for mounting the pivot axle;
- the inner arm disposed between the first and second outer side arms and having a first and second inner side arm, the first and second inner side arms having inner pivot axle apertures disposed adjacent the first end and configured for mounting the pivot axle;
- the pivot axle disposed in the inner pivot axle apertures and the outer pivot axle apertures;
- the pivot foot having a cylindrical axle interfacing surface extending between the first and second inner side arms, a valve tip interface disposed between the first and second inner side arms, and first and second retaining ring mounting portions, the first retaining ring mounting portion disposed between the valve tip interface and the first inner side arm, and the second retaining ring mounting portion disposed between the valve tip interface and the second inner side arm;
- and,
- the first and second retaining rings at least partially surrounding the pivot axle and partially rotatably mounting the pivot foot to the pivot axle.
A dual body rocker arm comprising:
- a first end, a second end, an outer arm, an inner arm, a substantially cylindrical pivot axle, and a pivot foot;
- the outer arm having a first and second outer side arm extending from the first end to the second end, and outer pivot axle apertures disposed adjacent the first end and configured for mounting the pivot axle;
- the inner arm disposed between the first and second outer side arms and having a first and second inner side arm, the first and second inner side arms having inner pivot axle apertures disposed adjacent the first end and configured for mounting the pivot axle, the first inner side arm having an interfering tab adjacent the first end and extending toward the second inner side arm, the second inner side arm having an interfering tab adjacent the first end and extending toward the first inner side arm;
- the pivot axle disposed in the inner pivot axle apertures and the outer pivot axle apertures;
- the pivot foot having a concave cylindrical axle interfacing surface extending between the first and second inner side arms, a valve tip interface disposed between the first and second inner side arms, and at least one interfering block, the at least one interfering block disposed between the valve tip interface and one of the first inner side arm and second inner side arm, the at least one interfering block configured to interfere with at least one of the interfering tabs.
A dual body rocker arm comprising:
- a first end, a second end, an outer arm, an inner arm, a substantially cylindrical pivot axle, and a pivot foot having an axle interfacing surface and a valve tip interface;
- the outer arm having a first and second outer side arm extending from the first end to the second end, and outer pivot axle apertures disposed adjacent the first end and configured for mounting the pivot axle;
- the inner arm disposed between the first and second outer side arms and having a first and second inner side arm, the first and second inner side arms having inner pivot axle apertures disposed adjacent the first end and configured for mounting the pivot axle;
- the pivot axle disposed in the inner pivot axle apertures and the outer pivot axle apertures;
- and,
- a means for retaining the pivot foot in a position suitable for engagement by a valve tip.
