Abstract
An input shaft and an output shaft can rotate relative to each other. Pressure supplied to a pressure-responsive actuator depends on the axial position of a movable valve member. A transmission arrangement serves to move the valve member only in the axial direction as the input and output shafts rotate relative to each other. The valve member and each of the input and output shafts are wholly outside one another.
