Abstract

Percussion apparatus of the hammer type or percussion drill, comprising a plunger firmly connected with a hammer head with a trephine disposed at the end of a drill rod capable of being pressed on both sides inside a cylinder and transmitting its displacements within the cylinder at the head of the hammer to the trepan, the percussion effect depending on the length of the stroke of the plunger, the frequency of the blows and the moving mass, characterized in that the drill rod or the head of the the hammer is rigidly coupled to the piston, which is hydraulically actuated so that the plunger and the drill rod or the plunger and the hammer head constitute said movable mass.
