Abstract:
A valve actuating system determines a shape of its jam nut surface as a function of a resultant force on a ball stud exerted by a rocker arm on the ball stud during operation of the valve train. The contact surface of the jam nut, which is pressed against an associated surface of the head of an engine, is a conical surface with an included angle that is generally twice the magnitude of an angle between a resultant force on the ball stud and a central axis of the ball stud and its associated jam nut. Certain accommodations can be made in order to reduce the cost of the system that would occur if perfect mathematical preciseness with a most preferred embodiment of the present invention is employed.
