    Abstract: A low-friction, boat-type, cold-formed rocker arm is provided. The rocker arm is of generally U-shaped configuration in transverse cross section throughout most of its length. An intermediate portion of the rocker arm has a concave interior surface extending there-across with a central opening through which a shank of a pedestal extends. One end portion of the rocker arm has a concave recess facing downwardly to receive the upper end of a push rod. The other end portion of the rocker arm has a rectangular opening in the bottom thereof. An axle extends between side walls of the rocker arm above the rectangular opening and a roller is rotatably mounted on the axle and has a circumferential portion exposed at the rectangular opening. The roller engages an end of a valve stem with rolling, rather than sliding, contact, resulting in lower friction during operation of the rocker arm.

    Abstract translation: 提供了低摩擦，船型，冷成型的摇臂。 摇臂在其大部分长度上横截面为大致U形构型。 摇臂的中间部分具有在其上延伸的凹形内表面，并且具有中心开口，基座的柄部通过该中心开口延伸。 摇臂的一个端部具有面向下的凹入凹部，以容纳推杆的上端。 摇臂的另一端部在其底部具有矩形开口。 轴在摇臂上方在矩形开口上方延伸，并且辊可旋转地安装在轴上，并且具有在矩形开口处露出的圆周部分。 辊子与阀杆的端部接合而不是滑动接触，导致摇臂操作期间的较低摩擦力。

    Abstract: Roller-tip rocker-arm for high-performance internal combustion engines, pivotable about a trunnion therethrough, having a roller in the tip thereof for contacting the stem of a valve depressed (i.e., in the engine, per se, "lifted" from its seat in the "closed" position) thereby and having on the other end (i.e., tail) thereof an arcuate surface for contacting and abutting the cooperatively shaped end of a pushrod, the latter of which lifts said tail, wherein the roller and arcuate surface are so positioned so that, at the point in the motion of the rocker-arm wherein the valve stem is at a location corresponding to the mid-lift of the valve to which it is attached, the angles (a) that the axis of the valve stem defines with the axis intersecting the axes of the roller and trunnion and (b) that the axis of the pushrod defines with the axis intersecting the center of the arcuate surface and the axis of the trunnion are both essentially 90 degrees.Such geometry eliminates the under-arcing and/or over-arcing of the roller-tip and/or pushrod characteristic of conventional rocker-arm operation and advantageously allows significantly improved engine performance.Optional means are provided on the rocker-arm to allow maximum accuracy in adjusting the position of rocker-arm mounting in the engine.

    Abstract: Valve train apparatus for an internal combustion engine having two poppet-type intake valves per cylinder. The valve train include a generally conventional rocker arm actuated either by a pushrod or an overhead camshaft. One end of the rocker arm actuates a first intake valve. A second rocker arm is pivotally mounted at one end to the cylinder head and contacts the first intake valve at its opposite end. An intermediate location on the second rocker arm contacts a second intake valve. The first intake valve engages a flanged element at the end of the valve stem opposite the valve head. The first rocker arm contacts the the top surface of the flanged element while the second rocker arm contacts a bottom surface of the flanged element. This construction permits flexibility in the positioning of the second valve. The second intake valve and its valve train apparatus can be rotated in a plane about the axis of the first intake valve to obtain optimum positioning of the second intake valve.

    Abstract: A rocker arm assembly for the operation of a valve in an internal combustion engine in which the rocker arm is pivotally mounted on a fulcrum supported by the cylinder head of the engine. A lubricant deflecting means mounted on the fulcrum is employed to deflect lubricant that flows through a push rod having a lubricant passage positioned therein and through an aperture in one end of the rocker arm onto the bearing means that pivotally supports the rocket arm on the fulcrum.

    Abstract: A valve rocker arm for transmitting reciprocatory movements between a poppet valve and its push rod, the rocker having surfaces on one side adjacent its opposite ends adapted to engage the driving and driven ends of the push rod and valve, respectively, an oppositely presenting pivotal bearing surface for the rocker on its opposite side intermediate the ends thereof and adapted to journal on a cooperating seat, the rocker arm being provided with an integral oil deflector at one end thereof in the form of a tab bent back over an oil hole extending through the surface seat for the push rod to catch oil delivered from the push rod and deflect it inwardly toward the pivotal bearing surface to lubricate the ball seat on which the rocker arm is pivotally mounted.
