Abstract

The present invention relates to a percussion device including a hammer piston, and including a valve 9 for controlling the reciprocating movement of the hammer piston in a cylinder. The control is obtained by pressurization chambers in said cylinder. The percussion device includes means for adjusting the stroke length of said hammer piston by adjusting the switching speed of said valve using said means, to thereby obtain a desired stroke length. Thereby, a desired stroke length of the hammer piston is obtained in a simple and convenient manner. The present invention also relates to a method.
