A sleeve body (63) with bearings interposed between the sleeve body (63) and a center shaft portion (44) is integrally coupled to an oil pulse generator (60). A coupling body (70) is rotatable together with the output portion (44). Balls (80) are fitted between an outer surface of the sleeve body (63) and an inner surface of the coupling body (70). Cam grooves (68, 68) are L-shaped in plan view, and formed in a portion of the outer surface of the sleeve body (63) at which the balls (80) are fitted. Rotation of the output portion (44) is transmitted from the coupling body (70) to the sleeve body (63) and the oil pulse generator (60) via the balls. When rotational speed between the sleeve body and the coupling body (70) is different, the balls (80) relatively turn in the cam grooves (68) to move the coupling body (70) forward against an urging force of a coil spring (85) so as to relieve an impact. |

A hydraulic hammer having an improved seal ring contacting with a piston (60). The hydraulic hammer having a cylinder (40') having an inner surface where a fluid groove connected to a passage for passing the fluid is formed, a piston installed in the cylinder to be elevated, and a first seal ring (62) for guiding the elevation of the piston (60), installed in an inner surface of the cylinder under the fluid groove and contacting with the piston, includes one or more second seal rings (64) having one or more grooves (65) or holes for passing the fluid, installed on the fluid groove and/or between the fluid groove and the first seal ring. Accordingly, the length of use before replacement of the seal ring installed between the piston and the cylinder can be extended, to thereby reduce the cost for operating the hydraulic hammer. |

| Un assemblage d'outils (4) permet de travailler un matériau (R), par exemple de concasser des roches. L'assemblage (4) comprend un montage d'outils (17) possédant une section fixe (18) et une section mobile (19) relativement à la section fixe (18) dans une direction de travail (DW) et une direction de retour opposée (DR). Un outil (34) est monté sur la section mobile (19) et accomplit un mouvement par rapport à celle-ci dans la direction de travail (DW) et de retour (DR). Un organe de butée (49, 50) sur l'outil (34) limite le mouvement relatif entre l'outil (34) et la section mobile (19), le mouvement s'accomplissant entre une position d'attente de l'outil et une position de fonctionnement de l'outil. Pendant une course de travail, l'outil (34) s'engage dans le matériau (R) et se déplace dans la direction de travail (DW) depuis la position d'attente dans la position d'actionnement et ensuite en synchronisme avec la section mobile (19) sous l'action d'une force de travail appliquée à l'outil (34) pour travailler le matériau (R). L'assemblage d'outils (4) comprend également un organe derappel (29) agissant entre la section fixe (18) et la section mobile (19) pour absorber les forces de travail appliquées de l'outil transférées depuis l'outil (34) à la section mobile (19), et produisant également une force de rappel à la section mobile (19) de manière à rappeler cette section mobile (19) dans la direction de retour (DR) lors de l'achèvement de la course de travail de l'outil (34). | ||||||
