摘要： A nut runner mounting structure for supporting one or more nut runner spindles includes a spindle supporting base plate, and at least one support pillar extending in parallel with the spindles and secured at its forward end to the base plate and at its rear end to a mounting structure support. Each support pillar has a tube element provided with a forward end piece and a rear end piece, and a tension bolt engaging the rear end piece and the base plate to exert an axial clamping force on the tube element. The forward end piece is formed with sharp edged teeth for penetrating into and forming matching teeth in the tube element and the base plate for locking the tube element against rotation. Clamping units are attachable to the tube elements for carrying additional equipment and connecting the structure to a mounting structure support.

摘要： A power nut runner with a torque responsive shut-off capacity includes a housing (11,12,13), and a rotation motor (10) connected to an output shaft (28) via a torque responsive release clutch (26) in which torque is transferred via a cam mechanism (31, 35, 36) between a driving clutch half (25) and a driven clutch half (27, 30, 39). A spring (32) is arranged to bias and displace a first one of the clutch halves (27, 30, 39) towards the other in an engagement direction, and a signal emitting release detecting sensor (46), is provided in the housing (11, 12, 13). An activation element (40) is arranged to be thrown off an abutting contact with the spring biassed clutch half (27, 30, 39) to reach an active position beyond its inactive low torque position as the spring biassed clutch half (27, 30, 39) is abruptly returned to its engagement position after an axial release movement.

摘要： A pressure operated shut-off valve for controlling a pneumatic circuit for instance a supply passage of a pneumatic tool, in response to the motive air supply pressure. The valve comprises a valve body that is continuously biased in its closing direction by a spring means and in its opening diection by the motive air supply pressure. If the air pressure drops below a predetermined minimum value the valve is automatically shifted to a closed position by the load of the spring means. A valve body controlled passage means supplies pressure air to the rear end of the valve body as the latter occupies its closed position, thereby making the closed position stable.
