摘要： A powered hammer includes a housing, a tool holder coupled to the housing and configured to hold a tool, a motor within the housing, a piston slideably mounted within the housing, a drive mechanism that converts rotary output of the motor into a reciprocating motion of the piston, a ram slideably mounted forward of the piston and that is reciprocatingly driven by the piston, and a beat piece support mounted in the housing forward of the ram. A beat piece is slideably supported by the beat piece support. The beat piece is repetitively struck by the ram and that in turn repetitively strikes an end of a tool when the tool is held in the tool holder to transfer the momentum of the ram to a tool. The beat piece support includes a seal that is slidingly engaged by the beat piece. The seal includes an absorbent material.

摘要： A percussion piston for use in a drilling apparatus includes a drill bit and at least three tubular parts which increase in diameter in a direction extending from the drill bit toward a rear end of the piston. The piston further includes flanges positioned between the tubular parts and a first corresponding delivery space at the rear end of the piston. At least two additional corresponding delivery spaces are positioned between the first corresponding delivery space and the drill bit. Channels allow the transport of pressurized hydraulic fluid to and from the first and additional corresponding delivery spaces such that an energy pulse produced by impact of the piston on the drill bit is almost completely absorbed by the drilled object.

摘要： Liquid driven hammer machine with a machine housing (1) and a hammer piston (2) moveable to-and-fro in guides (4,5) in the machine housing. The guides are made with an intermediate section (6) and end sections (7,8) on either sides thereof. The slot between the intermediate section and the hammer piston is less than, preferably one half of, the slot between the end section and the hammer piston at the end of the end section turned away from the intermediate section. The intermediate section has according to an advantageous embodiment an ax/al extension which is approximately one third of the length of the guide.

摘要： An impact motor comprises a housing (10) with a cylinder (11) therein, in which a reciprocating drive piston (40) via a gas cushion in a working chamber (44) of said cylinder (11) repeatedly drives a hammer piston (15) to impact on and to return from the neck (17) of a tool (20) carried by the machine housing (10). A piston groove (68) is provided adjacent to the front face (70) of the drive piston (40) and the peripheral part of said face (70) is rounded (71) towards said groove (68). A piston ring (41) is of steel having a temperature expansion coefficient substantially equal to the cylinder's (11) and is ground circumferentially to have a close sliding and sealing fit in the cylinder (11). The rounded (71) drive piston face (70) is adapted to the inner diameter of said ring (41) so as to permit the ring (41) to be forced into said groove (68) undeformed to ride on a elastically centering O-ring (69) of heat resistant rubber. The hammer piston (15) can alternatively have a similarly arranged steel or heat resistant plastics material piston ring (16) therearound or be machined to a sliding and sealing fit in the cylinder (11).

摘要： An impact power tool for use in delicate hand-working operations includes a body presenting a bore and a piston received within the bore and shiftable relative thereto. An impact transmitting member is also received in the bore and is shiftable relative to the body. This impact transmitting member is positioned axially in the bore by a mounting element interposed between the impact transmitting member and the body, the mounting element being resilient relative to the body. The piston is driven along a stroke length between an impact position engaging the impact transmitting member and an extended position out of contact with the member.

摘要： An impact device having a housing with hollow cylindrical aperture therein. The cylindrical aperture has a rotatable member within. The rotatable member has axial multiple rods thereon. On each rod of the rotatable member there are captive annular masses with a central aperture larger than the diameter of the rod to permit radial movement of the masses with respect to the rod. The rotatable member is driven by a motor and in turn rotates the annular masses which strike impact tools also supported within the housing. The kinetic energy of the annular masses is thereby transmitted via the impact tools to the outside of the impact device.
