摘要： A hydraulically actuated working device having a hydraulic cylinder, a hydraulic piston that can be displaced in the hydraulic cylinder, a drive unit part which has a motor and a pump, and a hydraulic line leading to the hydraulic cylinder. The drive unit part is designed in an electrically insulating manner, to provide an electrically insulating separating layer, which passes through the working device in a crossing manner for electrical separation from the working device part with respect to an end of the hydraulic piston facing the drive unit part. The hydraulic line is guided through the separating layer, thereby also forming a partial region of the hydraulic line made of an electrically insulating material.

摘要： The invention relates to a hydraulic cylinder (6) with a hydraulically actuatable working piston (10) movable therein for transferring a working force to an object (20) to be processed outside of the hydraulic cylinder (6) accompanied by the buildup of a counterforce, wherein the working piston (10) has an actuation surface (12), the actuation surface (12) borders an actuation space present between the working piston (10) and the hydraulic cylinder (6) in a working direction (R) in which the working force is transferred, and for executing an operation, hydraulic fluid can act for moving the working piston (10) in the working direction (R) toward the actuation surface (12), accompanied by an enlargement of the actuation space. The invention further relates to a hydraulic work tool (1) with a hydraulic cylinder (6), and to a shock absorption method using such a hydraulic cylinder (6). In order to achieve an effective shock absorption, the invention proposes that an intermediate piston (11) be arranged before the working piston (10) in the working direction (R), that the actuation space be divided by the intermediate piston (11) into an entrance space (14) and a working space (15), wherein the entrance space (14) is formed between a cylinder floor (21) and the intermediate piston (11), and the working space (15) is formed between the working piston (10) and the intermediate piston (11), that the hydraulic fluid can flow out of the entrance space (14) into the working space (15), accompanied by an enlargement of the working space (15), and that a mechanical coupling between the working piston (10) and the intermediate piston (11) can compensate for an actuation emanating from the hydraulic fluid located in the working space (15) given a loss in counterforce.

摘要： The invention relates to a hydraulically actuated piston (9) guided in a cylinder (8), and to a hydraulic working tool (1) having a working head (2), wherein the piston (9) has an impact surface (15) which borders an impact space (16) on the piston side provided between the piston (9) and the cylinder (8), and wherein hydraulic fluid (17) can act on the impact surface (15) by increasing the impact space (16) in order to move the piston (9) in an impact direction (r), and the piston (9) forms a limiting device (25) for a through-flow of the hydraulic fluid (17). According to the invention, in order to design a hydraulic piston guided in a cylinder or a hydraulic working tool in such a way that no undue signs of wear occur even during working processes with the sudden disappearance of the counter pressure, a hydraulic chamber (19) filled with the hydraulic fluid (17) is formed in the impact direction (r) after the limiting device (25), wherein a volume of the hydraulic chamber (19) is reduced according to the increase in the impact space (16), by means of the displacement of hydraulic fluid (17) out of the hydraulic chamber (19) and into the impact space (16) via the limiting device (25).

摘要： A method for milling a cutout using a milling cutter in a workpiece is provided. A longitudinal axis of the milling cutter is positioned in a first orientation relative to the workpiece to contact a first side of the workpiece. An enveloping cylindrical surface of the milling cutter is then used to cut a cutout which has a plurality of peripheral edges and rounded corners. The milling cutter is then placed in a second orientation which is angled relative to the first orientation. Thereafter, the enveloping cylindrical surface and an enveloping axial surface of the milling cutter are used to further cut the rounded corners of the cutout to form sharp corners.

摘要： The invention relates in first instance to a nut having a first part (11) which has a first through opening (O1), and having a second part (12) which has a opening (O2) having an opening contour, the parts (11, 12) being connected so as to be rotatable about a rotational axis (A) which passes through the openings (O1, O2), and the openings (O1, O2) being aligned with one another, in addition, the first opening (O1) on its inner face having a profile which extends in the peripheral direction and which is interrupted in the peripheral direction. In order to provide a nut which is quickly mountable on a threaded bolt, and which has a simple design that allows greater security against the nut coming off the threaded bolt, it is proposed that the opening contour of the second opening is non-circular. The invention further relates to a combination of a bolt (4) having a cross-sectional area with a nut (10).
摘要翻译：本发明首先涉及具有第一部分（11）的螺母，该第一部分具有第一通孔（O1），并且具有第二部分（12），该第二部分具有开口轮廓的开口（O 2），所述部分，12）被连接以能够围绕穿过所述开口（O1，O2）的旋转轴线（A）旋转，并且所述开口（O1，O2）彼此对准，此外，所述第一开口（O1 ）在其内表面上具有沿圆周方向延伸并且沿周向方向中断的轮廓。为了提供一种快速安装在螺栓上的螺母，并且具有简单的设计，其允许对螺母脱离螺栓的更大的安全性，因此建议第二开口的开口轮廓是非圆形的。本发明还涉及具有截面面积的螺栓（4）与螺母（10）的组合。
