Abstract
Ball drive mechanism includes a ball-like member on an eccentric output shaft of a rotary force motor which is received in a transversely extending cylindrical socket on a valve member. The outer diameter of the ball-like member is substantially the same as the inner diameter of the cylindrical socket to provide line contact therebetween at some distance radially offset from the longitudinal axis of the valve member which is at least as great as the eccentric offset, whereby the rotary output of the rotary force motor is translated into both linear and rotary movement of the valve member.
