    Abstract: An internal combustion engine including an engine housing having a cam chamber and an aperture providing access to the cam chamber. The engine also includes an insert at least partially made from plastic received within the aperture, a crankshaft coupled to the engine housing for rotation about a crank axis, and a cam shaft defining a cam shaft axis and at least partially made from plastic that is rotatably driven by the crankshaft. The cam shaft includes first and second ends and at least one cam lobe positioned between the ends. The first end is rotatably supported by the engine housing and the second end is rotatably supported by the insert. The engine also includes a metal portion coupled to either the insert or the cam shaft. The metal portion defines a flange having a face in contact with an adjacent surface of the other of the insert and the cam shaft.

    Abstract: A valve actuator assembly includes an axially moveable valve and a ramp roller thrust drive. The ramp roller thrust drive includes at least first and second opposed thrust plates, each plate including one or more ramps. A roller is positioned between corresponding opposed plate ramps and a rotation of one of the thrust plates relative to the other thrust plate causes the plates to move axially relative to one another such that axial motion is imparted to the valve.

    Abstract: A valve lift mechanism, in particular for internal combustion engines of motor vehicles, has a driven cam element, a valve control member which can be driven (translational movement or pivot rotation) by the cam element, and a flexible enveloping element, wherein the cam element is rotationally mounted. The enveloping element may be formed of plates and joint pins, to form a link chain or a roller chain, for instance, and it is movably connected to the valve control member in the plane perpendicular to the axis of rotation of the cam element.

    Abstract: In a valve system for a OHV horizontally-opposed, four-cycle internal combustion engine, valve camshafts are provided at crankcase portions for supporting a crankshaft, of left and right cylinder banks disposed on opposite sides of the crankshaft. Intake and exhaust valves are provided at cylinder heads and are opened and closed by pull rods operated by the valve camshafts. The aforementioned valve system achieves large reductions in the size and weight of the piston heads where the intake and exhaust valves of the internal combustion engine are disposed.

    Abstract: A push rod operated multi-valve V-type engine particularly adapted for use in motorcycles or like vehicles and which engine is air cooled. The engine employs a very simplified construction and overhead valve actuating mechanism utilizing push rods. The push rods are contained within push rod tubes formed at one side of the engine that provide a neat appearance and ease of servicing without adversely affecting the air cooling. A composite cylinder head construction is employed, as well as an improved and simplified lubricating system for the pair of driven camshafts. Furthermore, a decompression system is incorporated in the valve actuating mechanism so as to facilitate starting.
