Abstract

Hammering device functioning with pressure fluid of a hydraulic arrangement which hammering device comprises a body (16), (19) which can be attached to a working machine on which machine a hammering mass (3) is adjusted to be resting and to be moving which hammering mass is moved into a hammering position with the help of hydraulic pressure by directing the pressurized fluid into the ring-shaped, first chamber space (6) wherein the hammering mass (3) when it is moving into a hammering position compresses gas in the chamber space (Kl) located at the first side of the hammering mass (3) and in order to perform the hammering movement with the hammering mass (3) to the hammering element (5), (27) the flow of hydraulic pressure is blocked to the first chamber space (6) and the access for pressure fluid is allowed away from the first chamber space (6) with the help of the valve (2). In order to remove the pressure fluid fast from the first chamber space (6) the ring-shaped, second chamber space (7) is adjusted to be an extension for the first chamber space (6) and a ring-shaped valve (2) which comprises a closing ring is adjusted between the mentioned chamber spaces (6), (7) the port of which valve is formed of a group of holes which holes are located in the mentioned closing ring.
