Abstract
An impact mechanism device for a hand power tool comprises at least one impact mechanism including at least one driven cylinder and at least one piston driven in an axial direction by the at least one driven cylinder via a cam mechanism, and at least one planetary gearing configured to drive the at least one driven cylinder and the at least one piston. The at least one piston is positioned at least partially inside the at least one driven cylinder.

An impact mechanism device for a hand power tool, comprising:
- at least one impact mechanism including at least one driven cylinder configured for rotation and defining a radially inner space and at least one piston positioned at least partially inside the at least one driven cylinder within the radially inner space;
- at least one planetary gearing configured to drive the at least one driven cylinder and the at least one piston;
- and
- a cam mechanism configured to drive the at least one piston in an axial direction by rotation of the at least one driven cylinder, the cam mechanism including (i) a first form closure element fixedly extending from the at least one driven cylinder into the radially inner space, and (ii) a first groove defined on an outer surface of the at least one piston and configured to receive the first form closure element.
A hand power tool comprising:
- an impact mechanism device, including:
- at least one impact mechanism having at least one driven cylinder configured for rotation and defining a radially inner space and at least one piston positioned completely inside the at least one driven cylinder within the radially inner space;
- at least one planetary gearing configured to drive the at least one driven cylinder and the at least one piston;
- and
- a cam mechanism configured to drive the at least one piston in an axial direction by rotation of the at least one driven cylinder, the cam mechanism including (i) a first form closure element, and (ii) a first groove defined on an outer surface of the at least one piston and configured to receive the first form closure element.

- and
- a cam mechanism configured to drive the at least one piston in an axial direction by rotation of the at least one driven cylinder, the cam mechanism including a first groove and a second groove defined on the outer surface of the at least one piston, wherein the first groove extends completely around the at least one piston, wherein the second groove extends completely around the at least one piston, and wherein the first groove is different from the second groove.
