Abstract
In a mass compensated impacting apparatus composed of at least one pair of impacting tools and a common tool carrier supporting the tools, there is provided a two-mass vibration excitation system associated with each tool and including vibrating masses which are positively linearly guided in an essentially non-resilient manner, and a unit driving the vibratory masses with phase relationships such that the resulting average of all mass forces becomes at least approximately zero.
