    Abstract: A rocker arm assembly for use in internal combustion engines comprising a rocker arm member having a longitudinal extent and including bearing means for mounting the member for oscillation about an axis perpendicular to its longitudinal extent. An insert body defining a push rod seat recess is press fitted in an end of the rocker arm member to extend transversely to the axis of oscillation. The insert has a first generally cylindrical end portion of a first diameter and a second axially aligned generally cylindrical end portion of a smaller diameter. The first end portion is spaced from the second end portion by an intermediate transition surface which is inclined relative to the axis of the cylindrical end portions. The push rod seat recess extends axially into the first end of the body. The relationship of the insert end portions and the transition surface prevents loosening of the insert in the rocker arm body.

    Abstract: In an engine valve train, each rocker arm and its associate fulcrum are provided with cooperating inner and outer cylindrical surface contours carrying the reaction forces of rocker arm, the ratio of the radius of the outer surface contour being approximately in the order of 3:1 to 1.7:1 and preferably 2:1, the rocker arm and fulcrum having a cooperating retainer recess and pin, intermediate the ends of the associate bearing surface, to maintain alignment of these elements in substantially rolling contact with each other during pivotable movement of the rocker arm. In the preferred embodiment the radii of curvature of these bearing surfaces are selected in the ratio of 2:1 so as to obtain rolling motion known as cardanic motion, the recess being defined by opposed inclined flat surfaces and, the working surfaces of the pin being of semi-circular profile in substantial two-point contact with the surface defined by the recess.

    Abstract: A hydraulic valve gear includes a novel rocker arm and support structure and lubrication means therefor. The rocker arm is mounted for oscillating motion in the plane defined by the axes of the valve stem and hydraulic valve lifter only, which permits the use of a simple, reliable and inexpensive lubrication system for the valve gear.

    Abstract: A ONE-PIECE ROCKER ARM WITH STRAIGHT SIDE WALLS AND A SEMI-CYLINDER BOTTOM BEARING SURFACE IS MOUNTED ON A FULCRUM HAVING CYLINDRICAL STUB SHAFTS ON WHICH ARE MOUNTED NEEDLE BEARINGS AND BEARING HOUSINGS, THE ROCKER ARM BEARING SURFACE HAS A NO-LASH ENGAGEMENT WITH THE BOTTOM PORTION OF THE BEARING HOUSING WHICH ROTATES WITH THE ROCKER ARM AS A UNIT DURING A LOADED CONDITION OF THE VALVE TRAIN BUT ROTATES RELATIVE TO THE ROCKER ARM DURING THE UNLOADED VALVE TRAIN CONDITION DUE TO VIBRATIONS OF THE ENGINE AND INERTIA OF THE PARTS TO PROVIDE EVEN WEAR OF THE PARTS. THE FULCRUM IS PROVIDED WITH AN INTEGRAL SLEEVE SHAFT OF RECTANGULAR OR SQUARE CROSS-SECTION WHICH EXTENDS THROUGH THE ROCKER ARM BEARING SURFACE AND INTO A SLOTTED RECESS OR GROOVE IN THE ENGINE CYLINDER HEAD. A BOLT WHICH PASSES AXIALLY THROUGH THE SLEEVE SHAFT SECURES THE FULCRUM TO THE CYLINDER HEAD.

    Abstract: Valvetrain of an internal combustion engine, including a rocker support, a fulcrum, and a rocker. The rocker support is mounted to a cylinder head and fixed relative thereto. The rocker is positioned about the rocker support and partially in an axial aligning groove of the rocker support. The fulcrum is sandwiched between the rocker support and the rocker. The rocker oscillates about the fulcrum as forces are received and applied to a first and a second end of the rocker.
