The percussion apparatus comprises a striking piston and a control device (15) configured to vary a striking stroke of the striking piston, the control device (15) comprising a control cylinder (17), a control slide (16) mounted to move in translation in the control cylinder (17) in a direction of movement (D) and mounted to rotate in the control cylinder (17), and a main control chamber (26) delimited by the control slide (16) and the control cylinder (16). The percussion apparatus further comprises an adjustment device configured to adjust a range of variation of the striking stroke of the striking piston, the adjustment device comprising an adjustment member (41) configured to adjust the angular position of the control slide (16) in the control cylinder (17), and at least one fluid communication passage (44.1, 44.2, 44.3) arranged on the control slide (16) and configured to hydraulically limit the stroke of movement in translation of the control slide (16) in the direction of movement (D) depending on the angular position occupied by the control slide (16).
