A machine tool is disclosed. The machine tool has a tool receptacle for receiving a tool on a working axis, a housing, and a striking mechanism. An impact stop is provided for a beater or an intermediate beater. An impact absorber has two polymer-based absorber rings that are offset axially to one another and are disposed so that they overlap radially and has two iron-based disks disposed axially between the absorber rings.

A hammer drill has a body housing having a motor housing and a gear housing formed in one piece. An electric motor is fixed to the motor housing. A motion converting mechanism, a striking mechanism and a tool holder which form a striking mechanism part are housed in the gear housing so as to be movable with respect to the gear housing. During hammering operation, the striking mechanism part moves with respect to the gear housing under a biasing force of a coil spring, so that vibration caused by the hammering operation is reduced.

A hammer assembly for a power tool. The hammer assembly provides a first, proximal engagement portion couplable directly to a backside of the power. A second, distal engagement portion is directly connected to the first engagement portion. A head portion is directly connected to the second engagement portion. The second engagement portion provides one or more chambers, each chamber housing a spring for storing energy imparted by compressive forces against the head portion. Each spring directly interconnecting the first and second engagement portions through an open side of the chamber facing the first engagement portion. There is a gap between the first and second engagement portions, between their respective distal and proximal surface, which is spanned by the spring, enabling the latter to deflect before said surfaces contact under compressive loading.

A device (100) for placing a seal (J) on a mounting (S) including a vibration generator (10), that includes: a main body (11); a distal portion (12), movable relative to the main body, onto which a cap (13) having a contact surface (13a) for engaging with the seal is attached; and drive elements (14), configured to drive the distal portion in reciprocal translation relative to the main body, such as to place the seal on the mounting when the contact surface (13a) of the cap (13) engages with the seal (J) that is placed on the mounting (S). The device includes: a grasping handle (20), connected to the main body; and resilient connection elements (30a, 30b) that are located between the main body and the grasping handle and are configured such as to limit the propagation, in the grasping handle, of the vibrations generated by the reciprocal translation movement.

A power tool having a hammer mechanism includes a motor, a driving mechanism operably connected to the motor and configured to at least linearly drive a tool accessory along a driving axis, a tool body that houses the motor and the driving mechanism, an outer housing elastically connected to the tool body such that the outer housing at least partially covers the tool body and being slidable relative to the tool body in a first direction substantially parallel to the driving axis, a guide part configured to guide sliding movement of the outer housing relative to the tool body, and a handle including a grip part extending in a second direction, the handle being elastically connected at least to the outer housing and being movable relative to the outer housing in the first direction and in at least one direction that intersects the first direction.

A handle (200) for use with a power tool (100) having a coupling portion (204) and a gripping portion (206), a connector (228) for connecting the gripping portion (206) to the coupling portion (204), and a resilient deformable member (256) provided with and extended along the gripping portion (206). The coupling portion (204) is configured to detachably couple the handle (200) to the power tool (100). The gripping portion (206) is in connection with the coupling portion (204) for gripping by a user. The resilient deformable member (256) and the gripping portion (206) are integrated along length for simultaneous deformation.

A hand-held power tool includes a tool receiving area which has an inner receiving area that is designed to receive an insert tool and also includes a striking mechanism for applying striking pulses to the insert tool. A locking bolt is provided in order to lock the insert tool, wherein the locking bolt is connected to an operating element which is designed to position the locking bolt such that the insert tool is locked in a locked position and is unlocked in an unlocked position in order to be removed from the inner receiving area, and the locking bolt is paired with at least one damping element for at least partly damping a force acting on the insert tool in an idle running state of the hand-held power tool. The tool receiving area is paired with a receiving chamber in which the locking bolt and the at least one damping element are arranged. The locking bolt is at least partly received in a receiving area of a force transmission element, and the at least one damping element is arranged directly on the force transmission element in the receiving chamber.

A machine tool (1), in particular a drill hammer or chisel hammer, is described having a housing (5) having a grip region (7, 27) and an assembly (9) including an impact mechanism (11) and a drive device (13), the assembly (9) being arranged substantially within the housing (5) and being arranged movably relative to the housing (5). A center of gravity (15) of the assembly (9) is arranged at a distance from an impact axis (19). A sealing device (87) is provided to restrict an air flow between the assembly (9) and the housing (5), wherein the sealing device (87) is connected to the assembly (9) and to the housing (5) and encompasses the assembly (9) circumferentially relative to a vertical direction (Y) of the machine tool (1).

A hand-held processing tool with a housing that includes at least two housing parts is disclosed. The housing parts each have a side edge which are directly adjacent to one another in the assembled state of the housing. A recess is provided in at least one partial region of the side edges of at least one of the two housing parts such that the side edges of the at least two housing parts are spaced apart from one another in the at least one partial region.
