Abstract

A drill hammer (1 ) includes an air distribution chamber (12) in a rear end of a piston (14) and a bore that extends to a front end. A chamber divider (3) extends from a back-head to slidably engage inside the distribution chamber (12) and a control tube (2) slidably engages inside the bore. An air supply passage (11) is provided between the control tube (2) and the chamber divider (3). An exhaust port (19) from the drive chamber (18) extends through the chamber divider (3) to an inside of the control tube (2). A distribution port to alternately supply a drive chamber (18) and return chamber (23) extends through the piston (14) from the distribution chamber (12).
