摘要： A tool for disassembling a pipe or tube from a push-to-connect fitting is provided. The tool includes a first body and a second body pivotally coupled to the first body. A pair of first fingers are pivotally coupled to the first body, each of the first fingers having a first semi-circular surface, the first semi-circular surfaces cooperating to engage the pipe or tube adjacent the collar. A pair of second fingers are coupled to the second body, each of the second fingers having a second semicircular surface, the second semi-circular surfaces cooperating to engage the push-to-connect fitting. Wherein when the first body is rotated from a first position to a second position, the pair of first fingers moves a fitting collar axially relative to the pipe or tube.

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： Fittings that generally include a unitary body having an outer surface and an inner lumen forming a void within said unitary body. The lumen is configured to receive threads for mating with the threads of a female sub end of a pipe or tube. The outer surface includes at least one aperture for receiving a tool that can be inserted within said aperture so as to rotate the fitting about an axis that extends through the lumen of the unitary body. The at least one apertures provide a safe and convenient way to tighten and loosen the fitting during the process of coupling pipe or tubing.

摘要： An automatic oil return structure is provided. The automatic oil return structure has an oil storage bag, a piston, and a main body assembly. The piston has an oil storage chamber. The main body assembly has a main channel, a piston oil channel, a pressure regulating channel, a control channel, an operation channel, a minor channel, and an oil return channel. When the pressure of the main channel achieves a limit pressure, the pressure pushes the control blocking assembly away such that the pressure regulating channel communicates with the communication channel, and the pressure also pushes the operating assembly away such that the minor channel communicates with the return channel. At the same time, the pressure of the oil storage chamber pushes the oil blocking assembly, so as to isolate the oil storage chamber from the main channel, and the oil storage chamber communicates with the oil return channel.

摘要： A crimper device can facilitate sheathing of a stent frame for vascular delivery. The device can include first and second components that rotate relative to each other to drive radial movement of one or more compression members of the device. The one or more compression members can direct and balance a compressive force within an aperture of the device. In use, the stent frame can be positioned within the aperture and be compacted by actuation of the compression members.

摘要： A swage tool includes a power unit connected to a yoke. The power unit exerts vertical force on a die block. The yoke holds swage dies in place and opposes the force exerted by the die block. The die block transfers the load exerted by the power unit into the swage dies, which surround the connector. The swage dies convert vertical force from the power unit into a radial swage on the connector. Quick release endplates hold the swage dies in place in the yoke and the die block. A yoke shroud keeps broken pieces of the yoke together if the yoke fails. A counter records the number of swages made by the tool. A rotating handle, a stand, remote wireless actuation and swage die identification imprints are also provided.
