Embodiment Construction
[0027] See exemplary Figures 1-8B, these picture Shown is a swivel linkage assembly 100 and a cylinder-piston assembly 4 attachable to a reaction support 3 of a housing 2 of a tool 1 for tightening or loosening threaded fasteners.
[0028] The tool 1 , parts of which are not shown in FIGS. 1-7 , comprises a housing 2 having two housing parts, a cylinder part and a drive part. The cylinder-piston assembly 4 is arranged in the cylinder section and comprises a cylinder 5, along a piston axis or a first axis A 100 A piston 6 capable of reciprocating movement in the cylinder 5 and a piston rod 7 connected with the piston 6 . A known lever-type ratchet mechanism, not shown, is arranged in a drive portion connected to and drivable by the cylinder-piston assembly 4 and includes a ratchet. The ratchet can revolve around the axis A perpendicular to the piston 100 The rotational force axis rotates. The ratchet is connected to a drive element which, during operation of the tool 1 , re...

An apparatus for supplying fluid to a device for tightening or loosening a fastener, comprising: a first fluid transfer element (130) having a first axis and connectable to a housing of the device; a second fluid The transmission element (140) is rotatably connected to the first fluid transmission element (130) around a second axis approximately perpendicular to the first axis; the third fluid transmission element (150) is around a third fluid transmission element approximately perpendicular to the second axis. the axis and the second element (140) are rotatably connected and connectable to the fluid transfer line; and the first fluid conduit and the second fluid conduit pass through the first fluid transfer element, the second fluid transfer element and the third fluid transfer element Fluid is transferred back and forth between the device and the fluid transfer line. The first fluid transfer element is rotatable 360° about the first axis; the second fluid transfer element is rotatable 360° about the second axis; and the third fluid transfer element is rotatable less than 360° about the third axis.
