Abstract

The invention relates to the field of breaking up various materials and surface layers. The machine contains a tube (1) with an impact device. The tube is enclosed by a housing (4) having a handle. A holder (3) for a tool (2) is attached to the housing (4), and two guides and a pneumatic damper are arranged between the housing and the tube, the pneumatic damper constituting a number of elements movable in the axial direction and arranged on the tube. One of the guides is designed in the form of balls (5) which are inserted in bores in the housing (4) between the tool holder (3) and the tube (1). One of the elements of the pneumatic damper is designed as a ring (10) with an outer annular recess in which an elastic element (11) is located, the outer surface of which interacts with the inner surface of the housing (4) and forms the second guide. The invention can be used to improve the vibration behaviour of impact machines. <IMAGE>
