Abstract
A rotary impulse device for an air motor or electric motor drive designed to produce an adjustable output torque is provided. The driven output shaft or impulse member has a cam surface driven by a driver which is axially or radially movable in a driving cage mechanism whereby the torque developed by the impulse device cyclically varies between zero and a predetermined adjustable maximum quantity. Due to the cyclical variation in the torque developed there is no impact component of the torque delivered and therefore the tightening torque will not increase as the number of torque cycles increases.
