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 (K1) 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.
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) in which case the hammering mass (3) when it is moving into a hammering position compresses gas in the chamber space (K1) 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), characterized in that 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 in which case during the impact the pressure fluid is adjusted fast to move from the first chamber space (6) to the second chamber space (7) through the mentioned valve (2) when the volumes of the mentioned chamber spaces (6), (7) are changing due to the movement of the hammering piston (3).
Hammering device which creates impacts in two directions and functions with the pressure fluid of a hydraulic arrangement which hammering device comprises a body (16), (19) which can be attached to a working machine on which body hammering mass (3) is adjusted to be resting and to be moving which hammering mass is being moved into a hammering position with the help of hydraulic pressure by directing the pressurized liquid into a ring-shaped first (6) or second chamber space (7) with the help of a valve (1) depending on the hammering direction in which case the hammering mass (3) when it is moving into a hammering position compresses gas in a chamber space (K1) or (K3) which is located at the first or second side of the hammering mass (3) and in order to perform the hammering movement with the hammering mass (3) to a hammering element (5) the flow of hydraulic pressure is correspondingly blocked to the first (6) or second chamber space (7) and the access for the pressure fluid away is allowed with the help of a valve (2) either from the first chamber space (6) or from the second chamber space (7), characterized in that in order to remove the pressure fluid fast either from the first (6) or second chamber space (7) the mentioned, 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 are located at the mentioned closing rings in which case during the impact the pressure fluid is adjusted to move fast from the first chamber space (6) into the second chamber space (7) through a valve (2) when the volumes of the mentioned chamber spaces (6), (7) are changing due to the movement of the hammering piston (3).
